ARM/MP: 814220—B-Cache maintenance by set/way operations can execute out of order.
Description:
The v7 ARM states that all cache and branch predictor maintenance operations
that do not specify an address execute, relative to each other, in program
order. However, because of this erratum, an L2 set/way cache maintenance
operation can overtake an L1 set/way cache maintenance operation, this would
cause the data corruption.
This ERRATA affected the Cortex-A7 and present in r0p2, r0p3, r0p4, r0p5.
This patch is the SW workaround by adding a DSB before changing cache levels as
the ARM ERRATA: ARM/MP: 814220 told in the ARM ERRATA documentation.

Currently 128M reserved for GPU in all the i.MX6 boards that is
requiring kernel to allocate CMA 320M. For the low end devices like 6SX

With Kernel 4.1, there is a new feature CMA can be calculated at DTS

moving the GPU memory to DTS is valid and can be configured for each

It's hardware issue that if there are interrupts in GPIO1, the system
will not enter lpsr suspend state.
gpio1_12 pin is used as headphone detect pin for wm8958 sound card. If
headphone is not plugged in, the gpio1_12 pin is high level. When lpsr
suspend without headphone plugged in, gpio will be powered down and
there will be a interrupt in the gpio1_12 pin.
So we should avoid thus interrupt. We fix this issue by configuring
gpio1_12 pin to non GPIO function before lpsr suspend.
Because ALSA will set SAI pins to sleep state before suspend, and will
not set them to default state after resume if cpu dai is not active. So
we'd better remove non SAI pins from SAI pin group, and let iomuxc to
control the gpio pin state.

In order to workaround the PRE SoC bug recorded by errata ERR009624, the
software cannot write the PRE_CTRL register when the PRE writes the PRE_CTRL
register automatically to set the ENABLE bit(bit0) to 1 in the PRE repeat mode.
In non-small y resolution cases(>9 lines), we choose to check the STORE_BLOCK_Y
field of the register HW_PRE_STRORE_ENGINE_STATUS to determine the bad window
to update the SDW_UDPATE bit of the PRE_CTRL register. According to the
description of the STRORE_BLOCK_Y field in block mode, the field indicates the
Y coordinate of the block currently being rendered. Thus, we should round up
the real display y resolution to 4 lines to align with the block high(the out-
standing lines are cropped by PRG and IPU). To maximize the safe window, we
just need to avoid updating the shadow bit during the last block of lines.
To conclude, the bad window for block mode is (store_block_y == 0 ||

MLK-11749: pinctrl: support pinctrl setting assertion via gpios
It's pretty common that on some reference design or validation boards,
one pin could be used by two devices on board, and the pin route is
controlled by a GPIO. So to assert the pin for given device, not only
the pinmux controller in SoC needs to be set up properly but also the
GPIO needs to be pulled up/down.
The patch adds support of a device tree property "pinctrl-assert-gpios"
under client device node. It plays pretty much like a board level pin
multiplexer, and steers the pin route by controlling the GPIOs. When
client device has the property represent in its node, pinctrl device
tree mapping function will firstly pull up/down the GPIOs to assert the
pins for the device at board level.

MLK-11093-2 dts: imx6ul-14x14-ddr3-arm2-emmc: enable HS200 support
Add ultra high speed mode pinctrl states to support eMMC HS200.
HW rework needed that changing both NVCC_SD and NVCC_NAND to 1.8v.

MLK-11093-1 dts: imx6ul-14x14-ddr-arm2: add SD1 eMMC support
The eMMC signals are reused from SD1 slot signals on MX6UL ARM2 board.
Thus a new dts is introduced to avoid such pin confliction.
Before using this dts, user has to do hw rework to connect eMMC IO
signals and disconnect SD1 Slot signals.

MLK-10584 bcmdhd: fix connect Adhoc network warnings
As part of starting up IBSS, CFG80211 driver needs BSS information to be
plumbed into it. Hence in DHD we call cfg80211_infrom_bss() and it needs whole
frame consist of IEs contained in beacon frame. But FW was passing frame buffer
with some extra bytes preceded and when same is plumbed into CFG80211 it was not
able to decode the frame and it ignores the frame as result we get such warnings.
Using latest FW delivered by Broadcom to fix the issue.
As well as wl_cfg80211.c changes are essential. This change is actually fix certain
warnings seen when moving between IBSS and BSS network mode.
Changes must be done in wl_cfg80211_change_virtual_iface() which you can find at
wl_cfg80211.c and this file is not specific wl tool.

Drop debug version with build date/time.
The kernel already has this information, and individual drivers
shouldn't duplicate that. This also eliminates the use of __DATE__ and
__TIME__, which make the build non-deterministic.
