Bring back CLK ASAP after cfg changed to make SINK devices active
on HDMI-PATH-ALWAYS-ON situation, this workaround for some TVs no
sound issue. at the moment, it's 8K@60Hz display situation.
On HDMI-PATH-ALWAYS-ON situation, we almost keep XFER always on,
so, for new data start, suggested to STOP-CLEAR-START to make sure
data aligned.

CMA alloc may failure due to page busy caused by isolated failure,
it's helpful to dump page owner stack for debug.
To use this debug, there should enable PAGE_OWNER debug first by
- CONFIG_PAGE_OWNER=y
- add “page_owner=on” to boot cmdline
then it will shows as following:

The Sonix webcam (idVendor=0x0c45,idProduct=0x636a)
can't support auto-suspend well on rockchip platforms.
With auto-suspend, the usb mic of the webcam fail to
start capture. So we need to disable auto-suspend for
this Sonix webcam.

The mst of yrgb/uv must start at a byte aligned address with a full
group of pixel.
For a pixel with NV15 format, the y channel has 10 bits and uv channel
has 5 bits. So limit the alignment to 8 pixel(10 bytes for Y, and 5 bytes
for UV) to meet this requirement.
For a pixel with NV12 format, we should limit the alignment to 2 pixel.

Show the CMA pages used by cma_alloc in meminfo node.
Tested on RV1126 EVB DDR3:
CmaTotal: 270336 kB
CmaAllocated: 44408 kB
CmaReleased: 225928 kB
CmaFree: 0 kB
The CmaTotal = CmaAllocated + CmaReleased, and the CmaFree is pages
under cma area unused by system.
The CmaAllocated can be calculated by CMA_DEBUGFS.
Tested on RV1126 EVB DDR3:
cat /sys/kernel/debug/cma/*/used
10756
346
The results from cma used is in page count, 1 page = 4kByte
CmaAllocated = 44408kB = 10756 + 346 pages

The userland (gralloc or libdmaheap) fixed to use a heap name "cma-heap"
to be the device name, without this patch, the dt file should named the
cma default node name as "cma". otherwise it is defaultly to be "reserved"
that make the userland fail to open the device.
This patch fixes the cma-heap default name to "cma-heap".

Add iomap support for non-tailpacking uncompressed data in order to
support DIO and DAX.
Direct I/O is useful in certain scenarios for uncompressed files.
For example, double pagecache can be avoid by direct I/O when
loop device is used for uncompressed files containing upper layer
compressed filesystem.
This adds iomap DIO support for non-tailpacking cases first and
tail-packing inline files are handled in the follow-up patch.
