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.
ENGR00216013-2 mx6: not call memblock_free after reserve memory.
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.
add a function to check the end address including reserved memory,
this API can provide the top address of phy memory,
it can be used to check if the phy memory is valild in some driver
like VPU.

high bus freq enable clock before bus freq resume, so the request
of high bus freq will be ignore until next high bus freq device is

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

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()

Consider the below scenario: there is one CPU enter idle state before
switch happen, and the CPU frequency is set on high point(1G with userspace
cpufreq profile). After cpufreq profile is switched to interactive, all of the
cpus's target_freq will be set to the current CPU frequency 1G. Then after one
sample window, interactive profile will revalue the current cpu loading in
every cpu(except idle cpu), and get the desired frequency and compared with
target_freq to decide up or down frequency. Until all of cpus's target_freq
is lower than desired frequency , down frequency will happen. But the idle
CPU's frequency has been set on 1G , so cpu frequency miss the chance to set
lower cpu frequency , although there is no loading in all of cpus.CPU frequency
will be down unless the idled CPU exit idle to revalue cpu loading and get the
right target_freq, in the worst case, it will never happen.
Now we can do this:
