MLK-11488-10 arm: imx: add A9-M4 power management

this patch adds A9-M4 power management, including
below features:

1. busfreq: M4 is registered as a high speed device
   of A9, when M4 is running at high speed, busfreq
   will NOT enter low bus mode, when M4 is entering
   its low power idle, A9 will be able to enter low
   bus mode according to its state machine;
2. low power idle: only when M4 is in its low power
   idle, busfreq is staying at low bus mode, low
   power idle is available for kernel;
3. suspend: when M4 is NOT in its low power idle,
   when linux is about to suspend, it will only
   force SOC enter WAIT mode, only when M4 is in
   its low power idle in TCM, linux suspend can
   enter DSM mode. M4 can request/release wakeup
   source via MU to A9.

as M4 can NOT switch its clk parent due to glitch MUX,
to handle this case, A9 will help switch M4's clk
parent, the flow is as below:

M4:
1. enter low power idle, send bus use count-- to A9;
2. enter wfi and only wait for MU interrupt;
3. receive A9's clk switch ready message, go into low
   power idle;
4. receive interrupt to exit low power idle, send request
   to A9 for increase busfreq and M4 freq, enter wfi
   and only wait for MU interrupt;
5. receive A9 ready message, go out of low power idle.

A9:
1. when receive M4's message of entering low power idle,
   wait M4 into wfi, hold M4 in wfi by hardware, gate
   M4 clk, then switch M4's clk to OSC, ungate M4 clk,
   send ready command to wake up M4 into low power idle;
2. when receive M4's message of exiting low power idle,
   wait M4 into wfi, hold M4 in wfi by hardware, gate
   M4 clk, then switch M4's clk to origin high clk,
   ungate M4 clk, send ready command to wake up M4
   to exit low power idle;

clk management: for every clk node, only when both A9 and

Here we use MU and hardware SEMA4 to achieve our goal, MU is
for communiation between A9 and M4, SEMA4 is to protect the
shared memory.

For clk management, we use shared memory to maintain the clk
status for both A9 and M4 side, and this shared memory is
protected by hardware SEMA4, A9 and M4 will maintain their

ENGR00274386-2 ASoC: imx-wm8962: Set MCLK source clock to 0Hz in hw_free()

When DAPM closed WM8962 after playback, its driver would prompt
'wm8962 0-001a: Unsupported sysclk ratio 500' due to the invalid
divisor calculated by WM8962 codec driver.

To fix it, we can work around by setting its MCLK source to 0Hz,
so the codec driver would never get an invalid divisor any more.
Since hw_params() would re-set the MCLK source, no need to worry
about any side-effect.

WM8962 needs its MCLK when powerup -- wm8962_resume(). Thus it's better
to control the MCLK in codec driver. Thus remove the clock enable in

   and there would be no log printing out after booting up.
 * Provide the sys interface to modify the mma8450 work modes. Then the higher
   layer can modify the the mma8450 work mode via the interface. It would be

   is defined as: MODE_STANDBY: 0  MODE_2G:1  MODE_4G:2  MODE_8G:3
