MLK-13793-3 regulator: anatop: Fix enable for vddpu with LDO bypass
Enabling the vddpu regulator at boot has no efect, since the enable call in
anatop will set it to power gated off. This leads to a hang in the VPU driver
if cpufreq does not get initialized before.
The anatop on i.MX6 requires that vddpu uses the same voltage level as vddsoc.
When it is initialized, vddsoc will have a default selector of 0
(Power gated off), but will use LDO_FET_FULL_ON since it is in bypass mode.
However, the local value saved for the vddsoc selector will remain 0.
When vddpu is enabled, it will use the local selector 0 from vddsoc and
will remain disabled.
Take into consideration the bypass mode when using the vddsoc selector for
vddpu.

This patch fixes crackling sound reported when running autorun-asrc.sh

85f57752b3 ("dmaengine: imx-sdma - correct
the dma transfer residue calculation") from v10-rc6.
Original commit message:
From: Nandor Han <nandor.han@ge.com>
Date: Tue, 11 Oct 2016 14:13:41 +0300
Subject: [PATCH] dmaengine: imx-sdma - correct the dma transfer residue
calculation
The residue calculation was taking in consideration that dma
transaction status will be always retrieved in the dma callback
used to inform that dma transfer is complete. However this is not
the case for all subsystems that use dma. Some subsystems use a
timer to check the dma status periodically.
Therefore the calculation was updated and residue is calculated
accordingly by a) update the residue calculation taking in
consideration the last used buffer index by using *buf_ptail* variable
and b) chn_real_count (number of bytes transferred) is initialized to
zero, when dma channel is created, to avoid using an uninitialized
value in residue calculation when dma status is checked without
waiting dma complete event.

Since commit commit
560a64749d1dd0ff ("ENGR00318936-2 input: keyboard: imx:
remove usless release interrupt enabled) the following problem happens:
- Keep any keypad key pressed
- Enter low power mode via "echo mem > /sys/power/state"
- Then we are no longer able to wake-up the system via the keypad
The reason for this behaviour is that the KRIE (Release Interrupt) is not
enabled.
In order to fix this problem, we should enable KRIE when a key is pressed
(KPKD bit is set) or enable KDIE when no key is pressed (KPKR is set).
This way we will always have a valid source of keypad interrupt no matter if
the system entered low power mode while a keypad key was pressed or not.

MGS-1923 [#imx-19] use device mutex to sync command operations
kernel mutex cannot be shared with gpu0,gpu1 and bridge mode together.
use device mutex to prevent the sync problem for gpu command operations.
this change is reasonable and fixed one hole in existing implementation.
but this patch cannot fix the GPU hang for MGS-2429.

MXSCM-217 imx: keep weak 2p5 power up when ENET WOL wakeup is enabled
When ENET wake up is enabled by wake-on-lan (WOL), the weak 2P5
ldo needs to keep power up even for LPDDR2 due to the ENET_PLL is
feed by the weak 2p5 ldo during DSM. If the weak 2P5 ldo is power
down the ENET module is power off hence it is not able to sense the
WOL interrupt and trigger the system resume.
