ENGR00333129 dts: imx6qdl-sabreauto: use external vmmc for sd3 optionally
SD3.0 cards require power cycle the card during suspend/resume,
or the card re-enumeration after resume will fail to be identified
as UHS card since the card is already working on 1.8v mode and refuse
to ack the S18R request, thus, it will then work on normal high speed
mode instead.
We have to use external vmmc regulator to power cycle the card during
suspend/resume to reset card signal voltage to 3.3v frist for the later
1.8v voltage switch.
However, due to the sabreauto board limitation, we can not use external
regulator to powere off card by default since the card power is shared
with card detect pullup. Disabling the vmmc regulator will also shutdown
the cd pullup which causes incorrect illusion of card exist.
(e.g. plug out the card, mmc core wll think the card is exist since cd pin
is low but it never can find the card)
HW rework removing R695 and enable PAD internal pullup is needed to
fix this isssue.
User can manually open the mask of vmmc in dts to enable using external
regulator if your board has done the rework as said above.
Or by default we still do not power off card during suspend.

ENGR00287983-2 imx restart: add another WDOG2 reset support for ldo-bypass
For ldo-bypass mode on i.MX6Q/DL sabresd board, we will use another WDOG2 to
reset external pmic to trigger POR event, rather than WDOG1 to trigger WDOG
event in ldo-enable mode. We need to consider it in common mxc_restart().
On i.MX6SL sabresd board we use WDOG1 to trigger WDOG event both ldo-bypass and
ldo-enable mode.
Remove useless code for release interrupt enabled, because we check status by
timer rather than release interrupt. Remove the code which may disable depress
interrupt. Also make sure enable depress interrupt in suspend function.

ENGR00318936-1 input: keyboard: imx: add pm_stay_awake and pm_relax
There is a small window after system suspend but timer scan function
didn't finish timely, in this case, system enter suspend without kpp
interrupt enabled and failed to resume back if key depressed.We add
pm_stay_awake and pm_relax to make sure system suspend flow abort in
this case.
