3f2a09d57b ARM: davinci: da850: use clk->set_parent for async3
The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.

6fc9ebbdeb ARM: davinci: Move clock init after ioremap.
Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem.
The davinci_common_init() function must be called before the ioremap, so
the clock init is now split out as separate function.

258fc497fa Fix for more theoretical than practical OOPS on first turn on of a exynos
power domain, if there was no turn off before. Usually all power domains
 are on, so the first action is to turn off but some older bootloaders
 might behave differently.

91ea692f87 Here are the latest bug fixes for ARM SoCs, mostly addressing
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

b7a1922814 ARM: dts: dra7x: Support QSPI MODE-0 operation at 64MHz
According to Data Manual(SPRS915P) of AM57x, TI QSPI controller on
DRA74(rev 1.1+)/DRA72 EVM can support up to 64MHz in MODE-0, whereas
MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better
throughput.

626180785f ARM: dts: dra7x: Remove QSPI pinmux
DRA7 family of processors from Texas Instruments, have a hardware module
called IODELAYCONFIG Module which is expected to be configured. This
block allows very specific custom fine tuning for electrical
characteristics of IO pins that are necessary for functionality and
device lifetime requirements. IODelay module has it's own register space
with registers to configure various pins.

According to AM572x TRM SPRUHZ6E October 2014–Revised January 2016[1]
section 18.4.6.1 Pad Configuration, in addition to pinmuxing(MUXMODE),
when operating a pad in certain mode, Virtual/Manual IO Timing Mode must
also be configured to ensure that IO timings are met (DELAYMODE and
MODESELECT fields of pad's IODELAYCONFIG module register). According to
section 18.4.6.1.7 Isolation Requirements of above TRM, when
reprogramming MUXMODE, DELAYMODE, and MODESELECT fields, there is a
potential for a significant glitch on the corresponding IO. It is hence
recommended to do this with I/O isolation (which can only be done in
initial stages of bootloader). QSPI is one such module that requires
IODELAY configuration. So, this patch removes the pinmux for
QSPI for DRA74/DRA72 EVM as it needs to be done in bootloader (U-Boot)
and cannot be done in kernel.

Users should migrate to U-Boot v2016.05-rc1 or higher.

5da86baf69 ARM: omap2plus_defconfig: Fix warning due invalid RXKAD symbol value
Commit 648af7fca159 ("rxrpc: Absorb the rxkad security module") changed
the RXKAD Kconfig symbol from tristate to boolean but the commit didn't
update the omap2plus_defconfig that was enabling CONFIG_RXKAD as module.

This leads to the following warning when using the omap2plus_defconfig:

arch/arm/configs/omap2plus_defconfig:112:warning: symbol value 'm' invalid for RXKAD

54d03c5d8b ARM: dts: AM57xx/DRA7: Update SoC voltage rail limits to match data sheet
As per the data sheet starting from SPRUHQ0H (Nov 2015 - Latest[1]),
VDD_CORE can vary from 0.85v to 1.15v for AVS class0. VDD GPU/DSP
et.al. can range from 0.85v to 1.25V with AVS class0

Since dynamic voltage scaling is disabled for DRA7/AM57xx SoCs for
all SoC rails other than MPU, the bootloader is responsible for
setting up the AVS class0 voltage, however, with wrong voltage machine
constraints in dtb, regulator framework will lower the voltage below
the required voltage levels for certain samples in production flow.
This can cause catastrophic failures which can be pretty hard to
identify.

Update board files which don't match required specification.

5607959a4d ARM: dts: omap5-cm-t54: fix ldo1_reg and ldo4_reg ranges
ldo4_reg is connected to DSS, and should always be 1.8V. However the The
dts defines a range of 1.5V-1.8V, which requires somethings to set the
actual voltage at runtime. Currently we set the voltage in omapdss
driver.

As the voltage must always be 1.8V, let's just define the range to 1.8V
so that the driver doesn't need to deal with the voltage. In fact, the
driver should not touch the voltage, except in the cases where the
voltage needs to be changed at runtime.

I presume the situation is the same for ldo1_reg, used for CSI, although
I think it is not currently used in the mainline.
