Convert the SiRF UART driver from using the vendor-specific
"sirf,uart-has-rtscts" to the generic "uart-has-rtscts" DT property, as
documented by the Generic Serial DT Bindings.
The old vendor-specific property is still recognized by the driver for
backwards compatibility, but deprecated.

Document a set of generic properties for describing UARTs in a
device tree:
1. The GPIO modem control properties are currently duplicated across
hardware-specific binding documentation,
2. The property for dedicated RTS/CTS hardware flow control lines is
already supported by several drivers, albeit with a vendor-specific
prefix, hence make it generic.

This patch adds support for MIPI DPHYs found in Exynos5420-compatible
(5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from
earlier by different offset of MIPI DPHY registers in PMU controllers
(Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to
separate system register controllers (Exynos 5433 case). In both case
also additional 5th PHY (MIPI CSIS 2) has been added.

Northstar is a family of SoCs used in home routers. They have USB 2.0
and 3.0 controllers with PHYs that need to be properly initialized.
This driver provides PHY init support in a generic way and can be bound
with an EHCI controller driver.
There are (just a few) registers being defined in bcma header. It's
because DMU/CRU registers will be also needed in other drivers. We will
need them e.g. in PCIe controller/PHY driver and at some point probably
in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
avoid code duplication.

The XUSB pad controller allows PCIe lanes to be controlled individually,
providing fine-grained control over their power state. Previous attempts
at describing the XUSB pad controller in DT had erroneously assumed that
all PCIe lanes were driven by the same PHY, and hence the PCI host
controller would reference only a single PHY.
Moving to a representation of per-lane PHYs requires that the operating
system driver for the PCI host controller have access to the set of PHY
devices that make up the connection of each root port in order to power
up and down all of the lanes as necessary.

The NVIDIA Tegra XUSB pad controller provides a set of pads, each with a
set of lanes that are used for PCIe, SATA and USB.
A binding exists for the XUSB pad controller already, but it turned out
not to be flexible enough to describe all aspects of the controller. In
particular, the addition of XUSB support (for SuperSpeed USB) has shown
that the existing binding is no longer suitable. Mark the old binding
as deprecated and link to the new binding.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that its not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

Here's the big USB Gadget pull request. This time
not as large as usual with only 57 non-merge

The most important part here is, again, all the work

endpoints (except for control endpoint) exactly the
same. They all have the same amount of TRBs on the
ring, they all treat the ring as an actual ring with
a link TRB pointing to the head, etc.
We're also helping the host side burst (on
SuperSpeed GEN1 or GEN2 at least) for as long as
possible until the endpoint returns NRDY.
Other than this big TRB ring rework on dwc3, we also
have a dwc3-omap DMA initialization fix, some extra
debugfs files to aid in some odd debug sessions and
a complete removal of our FIFO resizing logic.
We have a new quirk for some dwc3 P3 quirk in some

This includes a few functional changes:
* new representation of MIC, SIC1 and SIC2 interrupt controllers,
* disabled by default SPI1, SPI2, SSP0 and SSP1 SPI controllers in
shared lpc32xx.dtsi file,
* added clock sources for SPI1 and SPI2,
* set default clock rate of HCLK PLL to main osc rate multiplied by 16.
Also there are some non-functional changes:
* flatten board DTS files by exploiting device node labels,
* add 'partitions' device node for NAND SLC / MTD OF,
* correct Atmel vendor prefix to describe on board AT24 EEPROMs,
* rename board DTS files by adding SoC name prefix.
Since now DTS files of LPC32xx boards match "^lpc32[2345]0-" pattern.

recent regressions. Changes are across several platforms, so
I'm listing every change separately here.
Regressions since 4.5:
- A correction of the psci firmware DT binding, to prevent
users from relying on unintended semantics
- Actually getting the newly merged clock driver for some OMAP
platforms to work
- A revert of patches for the Qualcomm BAM, these need to be
reworked for 4.7 to avoid breaking boards other than the one
they were intended for
- A correction for the I2C device nodes on the Socionext Uniphier
platform
- i.MX SDHCI was broken for non-DT platforms due to a change
with the setting of the DMA mask
- A revert of a patch that accidentally added a nonexisting
clock on the Rensas "Porter" board
- A couple of OMAP fixes that are all related to suspend after
the power domain changes for dra7
- On Mediatek, revert part of the power domain initialization
changes that broke mt8173-evb
Fixes for older bugs:
- Workaround for an "external abort" in the omap34xx
suspend/resume code.
- The USB1/eSATA should not be listed as an excon device on
am57xx-beagle-x15 (broken since v4.0)
- A v4.5 regression in the TI AM33xx and AM43XX DT specifying
incorrect DMA request lines for the GPMC
- The jiffies calibration on Renesas platforms was incorrect
for some modern CPU cores.
- A hardware errata woraround for clockdomains on TI DRA7

is the generic ADC based thermal driver. As it is going through the
thermal tree these will be picked up as a patch to that next cycle as that
is how the author preferred to do it.
- mounting matrix support. This new core support allows devices to provide
to userspace (typically from the device tree) allowing compensation for how
the sensor is mounted on the device. First examples are on UAVs but it
has a more mundane use on typical phone where the chip may be on the front
or the back of the circuit board and soldered at any angle. Includes
support for this ABI in ak8975 (which has an older interface, now
deprecated) and mpu6050.
* tools
- add a -a option to enable all available channels in generic_buffer sample.
Makes it somewhat easier to use.
* adis library and drivers
- support manual self test flag clearing. This has technically been broken
for a very long time - result is an offset on readings as the applied field
is on all the time.
* ak8975
- triggered buffer support
* bmc150
- spi support (including splitting the driver into core and i2c parts)
* bmp280
- oversampling support.
* dht11
- improved logging - useful to debug timing issues on this quirky device.
* st-sensors
- read each channel invidivually as not all support the optimization of
reading in bulk. This is technically a fix, but will need to be backported
if desired.
- support open drain and shared interrupts.
* ti-adc081c

MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better

IO-domain handling is part of the general register files, so should live
under the grf directly. This change allows the grf to be a simple-mfd and
the io-domains fetching the syscon regmap from that parent-node.

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Add driver for the TCON (timing controller) module. The TCON module
is a separate module attached after the DCU (display controller
unit). Each DCU instance has its own, directly connected TCON
instance. The DCU's RGB and timing signals are passing through
the TCON module. TCON can provide timing signals for raw TFT panels
or operate in a bypass mode which leaves all signals unaltered.
The driver currently only supports the bypass mode.

Freescale has stated [1] that the LVDS clock source of the IMX6 does not
pass the PCI Gen2 clock jitter test, therefore unless an external Gen2
compliant external clock source is present and supplied back to the IMX6
PCIe core via LVDS CLK1/CLK2 you can not claim Gen2 compliance.
Add a DT property to specify Gen1 vs Gen2 and check this before allowing a
Gen2 link.
We default to Gen1 if the property is not present because at this time
there are no IMX6 boards in mainline that 'input' a clock on LVDS
CLK1/CLK2.
In order to be Gen2 compliant on IMX6 you need to:
- Have a Gen2 compliant external clock generator and route that clock back
to either LVDS CLK1 or LVDS CLK2 as an input (see IMX6SX-SabreSD
reference design).
- Specify this clock in the PCIe node in the DT (i.e.,
IMX6QDL_CLK_LVDS1_IN or IMX6QDL_CLK_LVDS2_IN instead of
IMX6QDL_CLK_LVDS1_GATE which configures it as a CLK output).

Currently the reset-gpio DT property which controls the PCI bus device
reset signal defaults to active-low reset sequence (L=reset state,
H=operation state) plus the code in reset function isn't GPIO polarity
aware - it doesn't matter if the defined reset-gpio is active-low or
active-high, it will always result into active-low reset sequence.
I've tried to fix it properly and change the reset-gpio reset sequence to
be polarity-aware, but this patch has been accepted and then reverted as it
has introduced few backward incompatible issues:
1. Some DTBs, for example, imx6qdl-sabresd, don't define reset-gpio
polarity correctly:
reset-gpio = <&gpio7 12 0>;
which means that it's defined as active-high, but in reality it's
active-low; thus it wouldn't work without a DTS fix.
2. The logic in the reset function is inverted:
gpio_set_value_cansleep(imx6_pcie->reset_gpio, 0)
msleep(100);
gpio_set_value_cansleep(imx6_pcie->reset_gpio, 1);
so even if some of the i.MX6 boards had reset-gpio polarity defined
correctly in their DTSes, they would stop working.
As we can't break old DTBs, we can't fix them, so we need to introduce this
new DT reset-gpio-active-high boolean property so we can support boards
with active-high reset sequence.
This active-high reset sequence is for example needed on Apalis SoMs, where
GPIO1_IO28, used to PCIe reset is not connected directly to PERST# PCIe
signal, but it's ORed with RESETBMCU coming off the PMIC, and thus is
inverted, active-high.

Standardize the NAND controller/NAND chip DT representation. Now, all new
NAND controller drivers should comply with this representation, even if
they are only supporting a single NAND chip.
Existing drivers can keep support for the old representation (where only
the NAND chip was described), but are encouraged to also support the new
one.

Some types of ST Sensors can be connected to the same IRQ line
as other peripherals using open drain. Add a device tree binding
and a sensor data property to flip the right bit in the interrupt
control register to enable open drain mode on the INT line.
If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).

Main change is probably the added support for the new rk3399 soc
and necessary infrastructure changes surrounding it.
The biggest chunk is probably that clock code is now able to
handle multiple clock providers in one system, as the rk3399
has two of those. A general one and another smaller one in a
separate power domain. The rk3399 also uses another new pll type.
Thankfully it just fits nicely into our current structure.
It also needs some parts like the cpuclk mux parameters to be
a bit more flexible and an new fractional divider subtype without
gate.
Apart from this big change we have some more fixes and removal
of forgotten variables.

That FIFO resizing logic was added to support OMAP5
ES1.0 which had a bogus default FIFO size. I can't
remember the exact size of default FIFO, but it was
less than one bulk superspeed packet (<1024) which
would prevent USB3 from ever working on OMAP5 ES1.0.
However, OMAP5 ES1.0 support has been dropped by
commit aa2f4b16f8 ("ARM: OMAP5: id: Remove ES1.0

Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.
By documenting this compat string it may be used in DTSs shipped, for
example as part of ROMs. It must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a7792 IP block and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a7792-specific driver
code to be activated in an updated driver should the need arise.

Add fallback compatibility string for R-Car Gen 1 and 2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

The source and destination masters are reflecting buses or their layers to
where the different devices can be connected. The patch changes the master
names to reflect which one is related to which independently on the transfer
direction.
The outcome of the change is that the memory data width is now always limited
by a data width of the master which is dedicated to communicate to memory.
The patch will not break anything since all current users have the same data
width for all masters. Though it would be nice to revisit avr32 platforms to
check what is the actual hardware topology in use there. It seems that it has
one bus and two masters on it as stated by Table 8-2, that's why everything
works independently on the master in use. The purpose of the sequential patch
is to fix the driver for configuration of more than one bus.
The change is done in the assumption that src_master and dst_master are
reflecting a connection to the memory and peripheral correspondently on avr32
and otherwise on the rest.

The emmc-phy is fully enclosed in the general register files (GRF).
Therefore as seen from the device-tree it shouldn't be a separate platform-

adapt the binding without needing a fallback, as the binding hasn't been

This VDMA is a soft ip, which can be programmed to support
32 bit addressing or greater than 32 bit addressing.
When the VDMA ip is configured for 32 bit address space
the buffer address is specified by a single register
(0x5C for MM2S and 0xAC for S2MM channel).
When the VDMA core is configured for an address space greater
than 32 then each buffer address is specified by a combination of
two registers.
The first register specifies the LSB 32 bits of address,
while the next register specifies the MSB 32 bits of address.
For example, 5Ch will specify the LSB 32 bits while 60h will
specify the MSB 32 bits of the first start address.
So we need to program two registers at a time.
This patch adds the 64 bit addressing support to the vdma driver.

Merge tag 'pinctrl-v4.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control fixes from Linus Walleij:
"Here is a set of pin control fixes for the v4.6 series.
A bit bigger than what I hoped for, but all fixes are confined to
drivers, a few of them also targeted to stable.
Summary:
- On Super-H PFC (Renesas) controllers: only use dummies on legacy
systems. This fixes a serious ethernet regression on a Renesas
board.
- Pistachio: Fix errors in the pin table.
- Allwinner SunXi: fix the external interrupts to work.
- Intel: fix so the high level interrupts start working, and fix a
spurious interrupt issue.
- Qualcomm ipq4019: fix the number of GPIOs provided (bump to 100),
correct register offsets and handle GPIO mode properly.
- Revert the revert on the revert so that Xway has a .to_irq()
callback again.
- Minor fixes to errorpaths and debug info.
- A MAINTAINERS update"

The bindings for the "arm,versatile-flash" device was merged in
commit 3ba7222ac9
"arm/versatile: Add device tree support" but was never used
for anything.
Versatile flash chips are actually just standard CFI chips,
but they have one or two bits in a system controller to control
VPP and write protection. Let's use this compatible string in
conjunction with "cfi-flash" to indicate that we have a
normal CFI flash with some extra Versatile-specific protection.

On some SOCs PORTS_IMPL register value is never programmed by the
firmware and left at zero value. Which means that no sata ports are
available for software. AHCI driver used to cope up with this by
fabricating the port_map if the PORTS_IMPL register is read zero,
but recent patch broke this workaround as zero value was valid for
NVMe disks.
This patch adds ports-implemented DT bindings as workaround for this issue
in a way that DT can can override the PORTS_IMPL register in cases where
the firmware did not program it already.
