2G above address will be converted to gpu virtual address in i.MX6,
gpu baseaddr can be used to reduce contiguous memory address conversion,
the benifit for gpu applications and external memory consumers(VPU/IPU) have,
- gpu mmu performance penalty is reduce in most cases,
- more system memory can be exported for external use

Android Recovery UI framework uses FBIOPUT_VSCREENINFO with yoffset update
to update display.
Both elcdif and ipuv3 FB will set var.activate to be FB_ACTIVATE_FORCE in
driver's probe. User space will get the VSCREENINFO with activate been set
to FB_ACTIVE_FORCE. Each FBIOPUT_VSCREENINFO with only yoffset update will
make the driver reinit.The activate should be cleared once set_par() been
finished.
HDMI driver should only reinit hdmi only when the mode changed. fbmem will
broadcast MODE_CHANGE for each FBIOPUT_VSCREENINFO ioctl even it only have
yoffset update.

It can fix the bugs that there is no SOF after resume sometimes.
Without SOF after resume the device will go to suspend again,

The root cause is cam->enc_counter is not re-initialized to 0 when calls
STREAMOFF ioctl, and then in DQBUF ioctl wait_event_interruptible_timeout()
sees the condition is true and access cam->done_q queue which has no strict
check and could be empty.
This patch adds the re-initialization and the sanity check.
Also, add the pointer check for memcpy because the destination may be
NULL on UERSPTR mode.

The L2 cache controller(PL310) version on the i.MX6D/Q is r3p1-50rel0
The L2 cache controller(PL310) version on the i.MX6DL/SOLO/SL is r3p2
But according to ARM PL310 errata: 752271
ID: 752271: Double linefill feature can cause data corruption
Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2
Workaround: The only workaround to this erratum is to disable the
double linefill feature. This is the default behavior.
[in the commit:c483abdca0011c1342bad42f16925dd5a2c7c091]
ENGR00271977-1 imx6_defconfig: enable PL310_ERRATA_769419
There is one error in the commit log, the correct PL310 version in
i.MX6DL/SOLO should be r3p2, not r3p1-50rel0.
so, PL310_ERRATA_769419, will not apply to i.MX6DL/SOLO. But since we build
one image to support both i.MX6Q and i.MX6DL/SOLO, the ideal solution is to
manage this errata in dynamic way. Someone did post the patches here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/145593.html
As the discussion on the above link, Russell King, the ARM arch maintainer said:
"As I already said, there is _no_ point making the barrier conditional;
it's probably more expensive to make it conditional than just to execute
it every time. But we still might as well optimize it away if we are
running _only_ on platforms which _do_ _not_ have that errata."
So, we will turn on the PL310_ERRATA_769419 on both i.MX6D/Q and i.MX6DL/SOLO.

The baseAddress of contiguousVidMem is the actual physical address
which is not subtracted by gpu baseAddress, but the allocated physical address
has been subtracted by gpu baseAddress in gckVIDMEM_Lock,
so the invalid offset is produced and used to calculate the logical address.

One bd actually needs 4KB page size. So changed the iram_alloc()
size parameter to allocate a precise iram memory for bd.
This patch also removed the extra iram pool for SDMA due to its
insufficient total size: SDMA allows around 48 channels to work
simultaneously, so it's better to allocate memory from iram pool
directly.
[There will be 3KB size waste in sdma->channel_control, which is
640B but actually using 4KB due to 4KB alignment for iram pool.]

At mx6, if usb wakeup is not enabled, the PHY's power
will be off during the system suspend, so the dp/dm
will be unknown after the system resumes, it may wake up
controller at some boards since dp/dm's status satisfies
wake up condition. If the controller is waken up, the
PHCD will be cleared automatically.
According to IC requirement, after PHCD is cleared, we
need to wait 1ms before clear PHY's clock gate to wait
PHY's clock stable. At above condition, the PHCD is cleared
automatically, it may less than 1ms before we clear
PHY's clock gate, then, software operation to clear PHY's
clock gate will be useless. At this case, the PHY will works
abnormal, and cause the controller hang when we write some registers
(eg, portsc).

We have not implemented fully OTG support, so we can't call
otg_statemachine since the state machine may incorrect at current
dual-role switch design.
At existed code, it will call otg_statemachine, in fact, it doesn't
need. Besides, it causes one kernel dump at Sabreauto board due
to it calls gpio API at spin lock, but at Sabreauto board the
USB power GPIO is expanded by MAX7310 which calls i2c read/write
and will schedule itself.
