Because we have DISPLAY power down/up request when do suspend/resume,
EPDC/SPDC has been powered off and powered on again, thus re-initialization
is needed.

Hardware cannot support battery internal resistance and coulomb calculation,
estimate data only by battery voltage.The true battery voltage will change to
a bit lower about 50mV~500mV than normal voltage with playing game or video or
other consumption actions, then change back to normal voltage with finishing
playing game or video or other consumption actions in the discharger stage.

this patch is adding a ioctl for vpu to check the phy addr before vpu
start using this addr, this use case is common in some Direct Render case,
the VPU 's framebuffer phy memory is allocate by GPU, if the address given
by GPU have some wrong, like pass a virtual address, vpu will hang the system.
Add this IOCTL to be the goalkeeper, this IOCTL can check whether the phy
address was virtual memory or the address is within phy memory of your DDR.
The phy memory valild check is now doing best effort:
1. check whether is was allocated by vmalloc(), which must be a phy un-continus
2. check whether is was beyound DDR's top address, usually the other driver
pass a virtual address as a phy address.

- USB gadget disconnected when system boot kernel with USB connected. Commit
68b1c60f7f6c436340206679a18d61d9 induce the issue, call dr_discharge_line(1)
to ensure no abnormal usb wakeup interrupt happen after plug out the cable.
There are two cases cause dr_discharge_line(1) of fsl_otg_event() be called.
One case is switch the otg mode form Host mode to Device mode. Another case is
boot kernel with USB connected. The host_first_call is true when system boot
kernel with USB connected, otherwise it is false. So dr_discharge_line(true)
should not be called in fsl_otg_event() if host_first_call is true.
- USBOH3 clock is still on after plug out the cable when boot kernel with USB
connected, If the suspended bit is 0x1 and stopped is 0x0,the case is regarded
as suspend connected to usb charger. USB clock will be turn on, otherwise the
second suspend is processed without USB clock and it causes system hang. But
system boot kernel with cable connected, suspended is 0x1 and stopped is 0x0.
USB clock will be on by mistake. And stopped is cleared in dr_controller_run()
when system boot kernel with USB connected. We should check the suspended and
stopped bit before call dr_controller_run() to fix the issue.

For fast mode setting, ov5642_change_mode does not check the fps setting.
New mode in ov5642_change_mode will have to be the same FPS as previous mode.
Only schedule the fast setting if previous fps is same as new one.

If LUT 63 is busy and LUTs 0-31 are busy, the epdc_choose_next_lut
function was not correctly selecting an available LUT between 32-62.
Instead, it was returning 0. This fixes that issue by properly
offsetting the available LUT from the second 32-bit segment of the
64-bit LUT field.

3.modify battery max coulomb data to 99% in charger full stage and
modify battery max coulomb data to 100% in discharger stage,because
hardware cannot support battery internal resistance and coulomb
calculation.Battery voltage and coulomb may increase a bit in charger
stage,so keep max coulomb data 99% in charger full stage.

The origin ASRC driver did not support input and output wordwidth
config but an total wordwidth config instead. And the input wordwith
and output wordwidth are all fixed to 24 bit.
In this path, we do things below:
1 Update to use input wordwidth and output wordwidth config seperately
instead of an total wordwidth config.
2 Set corresponding DMA(input/output) buswidth according ASRC's input
and output wordwidth config.
3 Support 16/24 bit input wordwidth and 24 bit output wordwidth.

Use allocated GPU resource to enable GPU.
Memroy address on imx6sl board starts from 0x80000000
and GC320 can access [baseAddress, baseAddress + 2G) only without MMU.
So to make GC320 work, baseAddres must be set to 0x80000000, and all
address sent to GC320 must be a offset to baseAddress. GC355 doesn't
need this baseAddress, that means it needs a real physcial adress,
rather than the offset to baseAddress.
Original code always change phsysical address to 'offset' before use it,
no matter it is used by GC355 or GC320, so only one of them can work.
Solution is to move address adjustion to arch specific part. So each
core can get what it wants.
