2de0745463 ARM: 9043/1: tegra: Fix misplaced tegra_uart_config in decompressor
commit 538eea5362a1179dfa7770dd2b6607dc30cc50c6 upstream.

The tegra_uart_config of the DEBUG_LL code is now placed right at the
start of the .text section after commit which enabled debug output in the
decompressor. Tegra devices are not booting anymore if DEBUG_LL is enabled
since tegra_uart_config data is executes as a code. Fix the misplaced
tegra_uart_config storage by embedding it into the code.

384cddbee4 ARM: footbridge: fix dc21285 PCI configuration accessors
commit 39d3454c3513840eb123b3913fda6903e45ce671 upstream.

Building with gcc 4.9.2 reveals a latent bug in the PCI accessors
for Footbridge platforms, which causes a fatal alignment fault
while accessing IO memory. Fix this by making the assembly volatile.

cc7b2fc909 ARM: dts; gta04: SPI panel chip select is active low
commit 181739822cf6f8f4e12b173913af2967a28906c0 upstream.

With the arrival of

commit 2fee9583198eb9 ("spi: dt-bindings: clarify CS behavior for spi-cs-high and gpio descriptors")

it was clarified what the proper state for cs-gpios should be, even if the
flag is ignored. The driver code is doing the right thing since

766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")

The chip-select of the td028ttec1 panel is active-low, so we must omit spi-cs-high;
attribute (already removed by separate patch) and should now use GPIO_ACTIVE_LOW for
the client device description to be fully consistent.

160237c192 DTS: ARM: gta04: remove legacy spi-cs-high to make display work again
commit 07af7810e0a5bc4e51682c90f9fa19fc4cb93f18 upstream.

This reverts

commit f1f028ff89cb ("DTS: ARM: gta04: introduce legacy spi-cs-high to make display work again")

which had to be intruduced after

commit 6953c57ab172 ("gpio: of: Handle SPI chipselect legacy bindings")

broke the GTA04 display. This contradicted the data sheet but was the only
way to get it as an spi client operational again.

The panel data sheet defines the chip-select to be active low.

Now, with the arrival of

commit 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")

the logic of interaction between spi-cs-high and the gpio descriptor flags
has been changed a second time, making the display broken again. So we have
to remove the original fix which in retrospect was a workaround of a bug in
the spi subsystem and not a feature of the panel or bug in the device tree.

With this fix the device tree is back in sync with the data sheet and
spi subsystem code.

BPi Pro needs TX and RX delay for Gbit to work reliable and avoid high

pull ups for the delays, so fix this for BananaPro.

50c701d94f ARM: dts: imx6qdl-sr-som: fix some cubox-i platforms
[ Upstream commit 2cc0bfc9c12784188482a8f3d751d44af45b0d97 ]

The PHY address bit 2 is configured by the LED pin. Attaching a LED
to this pin is not sufficient to guarantee this configuration pin is
correctly read. This leads to some platforms having their PHY at
address 0 and others at address 4.

If there is no phy-handle specified, the FEC driver will scan the PHY
bus for a PHY and use that. Consequently, adding the DT configuration
of the PHY and the phy properties to the FEC driver broke some boards.

Fix this by removing the phy-handle property, and listing two PHY
entries for both possible PHY addresses, so that the DT configuration
for the PHY can be found by the PHY driver.

commit 30596ae0547dbda469d31a2678d9072fb0a3fa27 upstream.

Commit 7536c7e03e74 ("of/fdt: Remove redundant kbasename function

Non-existent nodes would mistaken get created with a leading '/'. The
problem was fdt_path_offset() takes a full path while creating a node
with fdt_add_subnode() takes just the basename.

Since this we only add root child nodes, we can just skip over the '/'.

a9079d8d3b ARM: dts: ux500: Reserve memory carveouts
commit 8a996b2d8a03beae3cb6adfc12673778c192085d upstream.

The Ux500 platforms have some memory carveouts set aside for
communicating with the modem and for the initial secure software
(ISSW). These areas are protected by the memory controller
and will result in an external abort if accessed like common
read/write memory.

On the legacy boot loaders, these were set aside by using
cmdline arguments such as this:

  mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M
  mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M
  hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M
  mem=638M@385M

Reserve the relevant areas in the device tree instead. The
"mali", "hwmem", "mem_ram_console" and the trailing 1MB at the
end of the memory reservations in the list are not relevant for
the upstream kernel as these are nowadays replaced with
upstream technologies such as CMA. The modem and ISSW
reservations are necessary.

This was manifested in a bug that surfaced in response to
commit 7fef431be9c9 ("mm/page_alloc: place pages to tail in __free_pages_core()")
which changes the behaviour of memory allocations
in such a way that the platform will sooner run into these
dangerous areas, with "Unhandled fault: imprecise external
abort (0xc06) at 0xb6fd83dc" or similar: the real reason
turns out to be that the PTE is pointing right into one of
the reserved memory areas. We were just lucky until now.

We need to augment the DB8500 and DB8520 SoCs similarly
and also create a new include for the DB9500 used in the
Snowball since this does not have a modem and thus does
not need the modem memory reservation, albeit it needs
the ISSW reservation.

fa5f2e04da xen: Fix event channel callback via INTX/GSI
[ Upstream commit 3499ba8198cad47b731792e5e56b9ec2a78a83a2 ]

For a while, event channel notification via the PCI platform device
has been broken, because we attempt to communicate with xenstore before
we even have notifications working, with the xs_reset_watches() call
in xs_init().

We tend to get away with this on Xen versions below 4.0 because we avoid
calling xs_reset_watches() anyway, because xenstore might not cope with
reading a non-existent key. And newer Xen *does* have the vector
callback support, so we rarely fall back to INTX/GSI delivery.

To fix it, clean up a bit of the mess of xs_init() and xenbus_probe()
startup. Call xs_init() directly from xenbus_init() only in the !XS_HVM
case, deferring it to be called from xenbus_probe() in the XS_HVM case
instead.

Then fix up the invocation of xenbus_probe() to happen either from its
device_initcall if the callback is available early enough, or when the
callback is finally set up. This means that the hack of calling
xenbus_probe() from a workqueue after the first interrupt, or directly
from the PCI platform device setup, is no longer needed.

0a27398d89 ARM: OMAP2+: omap_device: fix idling of devices during probe
commit ec76c2eea903947202098090bbe07a739b5246e9 upstream.

On the GTA04A5 od->_driver_status was not set to BUS_NOTIFY_BIND_DRIVER
during probe of the second mmc used for wifi. Therefore
omap_device_late_idle idled the device during probing causing oopses when
accessing the registers.

It was not set because od->_state was set to OMAP_DEVICE_STATE_IDLE
in the notifier callback. Therefore set od->_driver_status also in that
case.

This came apparent after commit 21b2cec61c04 ("mmc: Set
PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4") causing this
oops:

commit 85b8350ae99d1300eb6dc072459246c2649a8e50 upstream.

CAN0 and CAN1 instances share the same message ram configured
at 0x210000 on sama5d2 Linux systems.
According to current configuration of CAN0, we need 0x1c00 bytes
so that the CAN1 don't overlap its message ram:
64 x RX FIFO0 elements => 64 x 72 bytes
32 x TXE (TX Event FIFO) elements => 32 x 8 bytes
32 x TXB (TX Buffer) elements => 32 x 72 bytes
So a total of 7168 bytes (0x1C00).

Fix offset to match this needed size.
Make the CAN0 message ram ioremap match exactly this size so that is
easily understandable.  Adapt CAN1 size accordingly.

da446be71e crypto: arm/aes-ce - work around Cortex-A57/A72 silion errata
commit f3456b9fd269c6d0c973b136c5449d46b2510f4b upstream.

ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected
by silicon errata #1742098 and #1655431, respectively, where the second
instruction of a AES instruction pair may execute twice if an interrupt
is taken right after the first instruction consumes an input register of
which a single 32-bit lane has been updated the last time it was modified.

This is not such a rare occurrence as it may seem: in counter mode, only
the least significant 32-bit word is incremented in the absence of a
carry, which makes our counter mode implementation susceptible to these
errata.

So let's shuffle the counter assignments around a bit so that the most
recent updates when the AES instruction pair executes are 128-bit wide.

[ Upstream commit 3cce9d44321e460e7c88cdec4e4537a6e9ad7c0d ]

Commit f77ac2e378be9dd6 ("ARM: 9030/1: entry: omit FP emulation for UND
exceptions taken in kernel mode") failed to take into account that there
is in fact a case where we relied on this code path: during boot, the
VFP detection code issues a read of FPSID, which will trigger an undef
exception on cores that lack VFP support.

So let's reinstate this logic using an undef hook which is registered
only for the duration of the initcall to vpf_init(), and which sets
VFP_arch to a non-zero value - as before - if no VFP support is present.

[ Upstream commit f77ac2e378be9dd61eb88728f0840642f045d9d1 ]

There are a couple of problems with the exception entry code that deals
with FP exceptions (which are reported as UND exceptions) when building
the kernel in Thumb2 mode:
- the conditional branch to vfp_kmode_exception in vfp_support_entry()
  may be out of range for its target, depending on how the linker decides
  to arrange the sections;
- when the UND exception is taken in kernel mode, the emulation handling
  logic is entered via the 'call_fpe' label, which means we end up using
  the wrong value/mask pairs to match and detect the NEON opcodes.

Since UND exceptions in kernel mode are unlikely to occur on a hot path
(as opposed to the user mode version which is invoked for VFP support
code and lazy restore), we can use the existing undef hook machinery for
any kernel mode instruction emulation that is needed, including calling
the existing vfp_kmode_exception() routine for unexpected cases. So drop
the call to call_fpe, and instead, install an undef hook that will get
called for NEON and VFP instructions that trigger an UND exception in
kernel mode.

While at it, make sure that the PC correction is accurate for the
execution mode where the exception was taken, by checking the PSR
Thumb bit.

78905c6ab1 ARM: p2v: fix handling of LPAE translation in BE mode
[ Upstream commit 4e79f0211b473f8e1eab8211a9fd50cc41a3a061 ]

When running in BE mode on LPAE hardware with a PA-to-VA translation
that exceeds 4 GB, we patch bits 39:32 of the offset into the wrong
byte of the opcode. So fix that, by rotating the offset in r0 to the
right by 8 bits, which will put the 8-bit immediate in bits 31:24.

Note that this will also move bit #22 in its correct place when
applying the rotation to the constant #0x400000.

56cc090c2b ARM: dts: aspeed: s2600wf: Fix VGA memory region location
[ Upstream commit 9e1cc9679776f5b9e42481d392b1550753ebd084 ]

The VGA memory region is always from the top of RAM. On this board, that
is 0x80000000 + 0x20000000 - 0x01000000 = 0x9f000000.

This was not an issue in practice as the region is "reserved" by the
vendor's u-boot reducing the amount of available RAM, and the only user
is the host VGA device poking at RAM over PCIe. That is, nothing from
the ARM touches it.

It is worth fixing as developers copy existing device trees when
building their machines, and the XDMA driver does use the memory region
from the ARM side.

[ Upstream commit 886f82ce9f1f4559c139fdb2d79d158999ca38cd ]

The GPIO controller is a GPIO controller followed by some SGPIO
controllers, which are a different type of device with their own binding
and drivers.

Make the gpio node cover the only conventional GPIO controller.

61bed86699 ARM: dts: exynos: fix USB 3.0 pins supply being turned off on Odroid XU
commit bd7e7ff56feea7810df900fb09c9741d259861d9 upstream.

On Odroid XU LDO12 and LDO15 supplies the power to USB 3.0 blocks but
the GPK GPIO pins are supplied by LDO7 (VDDQ_LCD).  LDO7 also supplies
GPJ GPIO pins.

The Exynos pinctrl driver does not take any supplies, so to have entire
GPIO block always available, make the regulator always on.

8ed2598696 ARM: dts: exynos: fix USB 3.0 VBUS control and over-current pins on Exynos5410
commit 3d992fd8f4e0f09c980726308d2f2725587b32d6 upstream.

The VBUS control (PWREN) and over-current pins of USB 3.0 DWC3
controllers are on Exynos5410 regular GPIOs.  This is different than for
example on Exynos5422 where these are special ETC pins with proper reset
values (pulls, functions).

Therefore these pins should be configured to enable proper USB 3.0
peripheral and host modes.  This also fixes over-current warning:

    [    6.024658] usb usb4-port1: over-current condition
    [    6.028271] usb usb3-port1: over-current condition
