182434f748 Samsung exynos-cpuidle updates for v3.16
- From Daniel Lezcano:
  This patchset relies on the cpm_pm notifier to initiate the
  powerdown sequence operations from pm.c instead cpuidle.c.
  Thus the cpuidle driver is no longer dependent from arch
  specific code as everything is called from the pm.c file.
 
 Note, this is based on tags/exnos-mcpm and tags/samsung-clk

06aa82e498 serial: uart: add hw flow control support configuration
8250 uart driver currently supports only software assisted hw flow
control. The software assisted hw flow control maintains a hw_stopped
flag in the tty structure to stop and start transmission and use modem
status interrupt for the event to drive the handshake signals. This is
not needed if hw has flow control capabilities. This patch adds a
DT attribute for enabling hw flow control for a uart port. Also skip
stop and start if this flag is present in flag field of the port
structure.

e0b0baadb7 tty/serial: at91: use mctrl_gpio helpers
On sam9x5, dedicated CTS (and RTS) pins are unusable together with the
LCDC, the EMAC, or the MMC because they share the same line.

Moreover, the USART controller doesn't handle DTR/DSR/DCD/RI signals,
so we have to control them via GPIO.

This patch permits to use GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI
signals.

9d4bde5fab dt: bindings: dwc2: fix required value for the phy-names property
"7408484 usb: gadget: s3c-hsotg: enable generic phy support" introduces
generic phy support to the dwc2.txt binding and the s3c-hsotg driver
which implements support for the binding. The binding documentation
incorrectly states that the phy-names property will be "device". The
binding example, driver, and one dts user all implement the phy-names
property as requiring "usb2-phy".

Fix the dwc2.txt binding documentation to correctly specify "usb2-phy"
as the appropriate value for phy-names.

2d5e447914 dt:/bindings: DRA7 ATL (Audio Tracking Logic) clock bindings
Audio Tracking Logic is designed to be used by HD Radio applications to
synchronize the audio output clocks to the baseband clock. ATL can be also
used to track errors between two reference clocks (BWS, AWS) and generate a modulated
clock output which averages to some desired frequency.
In essence ATL is generating a clock to be used by an audio codec and also
to be used by the SoC as MCLK.

To be able to integrate the ATL provided clocks to the clock tree we need
two types of DT binding:
- DT clock nodes to represent the ATL clocks towards the CCF
- binding for the ATL IP itself which is going to handle the hw
  configuration

The reason for this type of setup is that ATL itself is a separate device
in the SoC, it has it's own address space and clock domain. Other IPs can
use the ATL generated clock as their functional clock (McASPs for example)
and external components like audio codecs can also use the very same clock
as their MCLK.

The ATL IP in DRA7 contains 4 ATL instences.

76714d2c09 mfd: twl4030-power: Add recommended idle configuration
These settings are based on the "Recommended Sleep Sequences for
the Zoom Platform".

The settings assume most of the regulators are under control of
Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
Linux cannot do it.

For any board specific changes to these, let's patch them in as
changes to the generic data in the follow-up patches. This keeps
the board specific changes small.

Note that this does not consider the twl5030 errata 27 and 28.
That can be added later on after it has been tested. For more

e7cd1d1eb1 mfd: twl4030-power: Add generic reset configuration
The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.

In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.

Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.

Note we now also make the pdata const like it should be.
This allows use it for match->data with the device tree
related functions.

84cc8a7114 Quite a lot changes but it looks like DT approach is really paying off.
BG2Q joins Berlin SoC family with corresponding development board, DW
 gpio nodes for all SoCs. Most notably, we have settled clock bindings
 to allow us to continue on drivers requiring clocks and pinctrl bindings.
 Last but not least, BG2Q gained SDHCI support and is able to properly
 boot into userspace.
