MLK-11748 ARM: dts: imx7d-12x12-lpddr3-arm2-sai: configure gpio1_12 pin to non GPIO function before lpsr suspend
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.

MLK-11722 mxc IPUv3: PRE: Correct block mode bad update window calculation
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 ||
store_block_y >= DIV_ROUND_UP(y_resolution, 4) - 1).

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.

dpm_run_callback(): platform_pm_resume+0x0/0x4c returns -110
PM: Device
2090000.can failed to resume: error -110
It is caused by the flexcan is in disable state and the clock is disabled
by default while the CAN is not up. During resume, the calling of
flexcan_chip_enable will obviously fail due to no clock.
The issue only happened when CAN device is not up. If CAN is up, clock is there
and no issue will happen.
Because the CAN is always in disabled state by default if it's not up.
We don't have to disable it again during suspend and enable it after resume.
This patch simply the suspend/resume to only enter/exit disabled mode if CAN
is up.
