a3ac350793 ARM: OMAP2+: Fix WL1283 Bluetooth Baud Rate
Commit 485fa1261f ("ARM: OMAP2+: LogicPD Torpedo + Wireless: Add Bluetooth")
set the wrong baud rate for the UART. The Baud rate was 300,000 and it should
be 3,000,000 for WL1283.

5066d5296f ARM: omap2+: fixing wrong strcat for Non-NULL terminated string
Issue caught with static analysis tool:
"Dangerous usage of 'name' (strncpy doesn't always 0-terminate it)"

Use strlcpy _includes_ the NUL terminator, and  strlcat() which ensures
that it won't overflow the buffer.

f86a2c875f ARM: omap2+: am437x: rollback to use omap3_gptimer_timer_init()
The commit 55ee7017ee ("arm: omap2: board-generic: use
omap4_local_timer_init for AM437x") unintentionally changes the
clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K.

Unfortunately, the SyncTimer32K is starving from frequency deviation
as mentioned in commit 5b5c013591 ("ARM: OMAP2+: AM43x: Use gptimer
as clocksource") and, as reported by Franklin [1], even its monotonic
nature is under question (most probably there is a HW issue, but it's
still under investigation).

Taking into account above facts It's reasonable to rollback to the use
of omap3_gptimer_timer_init().

e79ab194d1 ARM: SoC platform updates for v4.10
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - Added support for the TI DRA71x family of SoCs in mach-omap2,
   this is an new variant of the the DRA72x/DRA74x automotive
   infotainment chips we already supported for a while.
 
 - Added support for the ST STM32F746 SoC, the first Cortex-M7
   based microcontroller we support, related to the smaller
   STM32F4 family.
 
 - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
   see http://elinux.org/RZ-G
 
 - SMP is now supported on the OX820 platform
 
 - A lot of code in mach-omap2 gets removed as a follow-up to
   removing support for board files in the previous release
 
 - Davinci has some new work to improve USB support
 
 - For i.MX, the performance monitor now supports profiling the
   memory controller using 'perf'
 
 Conflicts:
 arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init()
 is gone, calling of_clk_init(NULL) is sufficient now.

3ec5e8d82b ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in
 through -rc, or that just came a little too late given their size.
 
 The zx fixes make the platform finally boot on real hardware, the
 davinci and imx31 get the DT support working better for some of
 the machines that are still normally used with classic board files.
 One tegra fix is important for new bootloader versions, but the
 bug has been around for a while without anyone noticing.
 
 The other changes are mostly cosmetic.

With Device Tree booting the initialization is handled by

code is not needed anymore now that OMAP2+ is DT-only.

b7b23ffcf7 ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC support
When connecting an ethernet chip to the GPMC, such as smc91x
or smsc911x, a GPIO has to be requested to be used as an IRQ
and also the IO memory for a GPMC chip-select.

When booting with DT the chip-select allocation is handled
in a generic manner in the GPMC driver and the GPIO to IRQ
mapping is made by the DT core so this code is not needed
anymore now that mach-omap2 related boards are DT-only.

c2ce5fb3f3 ARM: OMAP: DRA7xx: Make L4SEC clock domain SWSUP only
Using HWSUP for l4sec clock domain is causing warnings in HWMOD code for
DRA7. Based on some observations, once the clock domain goes into an IDLE
state (because of no activity etc), the IDLEST for the module goes to '0x2'
value which means Interface IDLE condition. So far so go, however once the
MODULEMODE is set to disabled for the particular IP, the IDLEST for the
module should go to '0x3', per the HW AUTO IDLE protocol. However this is
not observed and there is no reason per the protocl for the transition to
not happen. This could potentially be a bug in the HW AUTO state-machine.

Work around for this is to use SWSUP only for the particular clockdomain.
With this all the transitions of IDLEST happen correctly and warnings
don't occur.

7abdb0e23e ARM: OMAP5: Add basic cpuidle MPU CSWR support
Add OMAP5 CPUIDLE support.

This patch adds MPUSS low power states in cpuidle.

        C1 - CPU0 WFI + CPU1 WFI + MPU ON
        C2 - CPU0 RET + CPU1 RET + MPU CSWR

Modified from TI kernel tree commit 605967fd2205 ("ARM: DRA7: PM:
cpuidle MPU CSWR support") except enable cpuidle for omap5 instead
of dra7.

According to Nishanth Menon <nm@ti.com>, cpuidle on dra7 is not
supported properly in the hardware so we don't want to enable it.
However, for omap5 this adds some nice power savings. Note that
the TI 3.8 based tree has other cpuidle states that we may be able
to enable later on.

On omap5-uevm, the power consumption eventually settles down to about
920mW with ehci-omap and ohci-omap3 unloaded compared to about 1.7W
without these patches. Note that it seems to take few minutes after
booting for the idle power to go down to 920mW from 1.3W, no idea so
far what might be causing that.
