Really disable pix/axi clock when SPDC is idle.

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.

There's only DISPLAY power down request setting before system suspends,
but without the paired DISPLAY power up request setting after resume.
This will cause ePxP/EPDC/SPDC module nonfunctional because the modules
will be powered down once pdn_req is asserted but not powered up again.
With this patch, ePxP/EPDC/SPDC survived (need reinitialize each, however)
on resume.

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.

Remove call memblock_free after reserve memory with memblock_allocate().
The function of memblock_free is to remove the memory block from reserve list
of memblock, it will totally lost the info about how much phy memory
we have.
Skipping call this can make the reserved memory be accountable in
memblock With no side-effect.
After doing this, we can know how much our phy memory is, then can add check
in our driver like(vpu) to check the phy memory valid or not before vpu start
use the 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.

OV's recommendation:
reset --------------------|_____|----------------
->| 1ms |<-
pwdn ----------|_________________________|------
->| 5ms |<- ->| 5ms |<-
->| 5ms |<-
This change makes the OV mipi camera be at a correct status
after reset, otherwise, the wrong status of OV mipi camera
will reduce the ~2.78V analog camera power to ~2.3V, which
causes random thin colorful lines on OV5642 CSI camera image
as OV5642 CSI camera uses the same analog power.

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.

There is one SOC bug if use LDO bypass, VDDARM_CAP will take 2ms to raise up
normal voltage when system resume back, longer than 40us before. Then it will
cause cpu hang if resume back.
Workaround:
We can disable LDO bypass at the last minute of suspend and enable LDO bypass
again as long as system resume back.

As before, raw I2C operation is added in suspend interface of cpufeq driver,so
that we can raise up cpu frequency and voltage after I2C driver suspended.But
the code is not platform independent if customer use another pmic whose I2C
slave address is different with pfuze.
Now, we rasie up cpu frequency and disable cpu frequency change in more earlier
than before. If system begin to suspend flow, we will do this.

Only need to save and restore PU field register value instead of the

When BUS freq is running at DLL off mode(24M or 50M), when CPU
freq is increased, we need to increase BUS freq to 400M setpoint
in order to achieve high performance when CPU is busy.
Signed-off-by: Anson Huang <b20788@freescale.com>

50M -> 528M bus freq change will cause system hang, root
cause is that we didn't set 50M as DLL off mode, it should
be DLL off mode.
And make sure bus, axi, ahb, ipg and ipg_perclk are at right
freq during all setpoints.
Can't disable PU LDO again if it is not enabled.

On MX6 SabreSD board, gpio_0 is muxed to clko to be
audio mclk and camera mclk. 24MHz osc clk is a stable
clock source, which can meet the requirement of audio
mclk and camera mclk. This patch sets clko parent
clock to be clko2 clock so that camera mclk and audio
mclk can source from osc clk.
There are 2 benifits after applying this patch:
1) clko's original parent clock(pll4_audio_main_clk)
can be gated off to save power or used by another
module.
2) ov5640/ov5642 camera most settings can reach
claimed 15fps or 30fps with no human eye recognizable
video quality downgrade.
