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.

Remove useless code for release interrupt enabled, because we check status by
timer rather than release interrupt. Remove the code which may disable depress

commit 916e43e1d6fb ("MLK-13570-3 usb: chipidea: core: change extcon

is not valid anymore on 4.y kernel, so revert most part and only keep

At v4.1 kernel, we can't get cable type at notifier, but at
extcon-usb-gpio.c notifies both VBUS and ID event, we had to
do special handling for ID event, and omit VBUS event. Current
implementation only supports ID extcon event.
If wakeup event occurs by extcon, it needs to call ci_irq again since the
first ci_irq calling at extcon notifier only wakes up controller, but
do noop for event handling.

The input MCLK is 12.288MHz, The desired output sysclk is 11.2896MHz
the sample rate is 44100Hz, with the pllprescale=2, postscale=sysclkdiv=1,
some chip may have wrong bclk and lrclk output in master mode. then there
will be no sound.
With the pllprescale=1, postscale=2, the output clock is correct. so use
this configuration to workaround this issue.

Before suspend, the sysclock select pll out as source, after resume
sysclock select the mlck as the source, so the sample rate is changed
the sound's pitch is shifted.
The issue is caused by the commit c1845da3d08de6cf2642fec74f7a46d05de6314d
Which removed the wm8960_configure_clocking() when bias level changes
from STANDBY to PREPARE, this patch is to add it back.

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.
