Add functionality to parse Audio Data Blocks from EDID data to
find out what modes of LPCM are suppored by the HDMI sink device.
The parsed settings are saved in the hdmi mfd. The HDMI audio driver
will check the settings when the audio stream is opened and will
then apply appropriate constraints.
If we are unable to read from the EDID, then we default to supporting
Basic Audio as defined by the HDMI specification (stereo, 16 bit,
32KHz, 44.1KHz, 48KHz PCM).

Lots (nearly all) mtd drivers contain nearly the similar code that
calls parse_mtd_partitions, provides some platform-default values, if
parsing fails, and registers mtd device.
This is an aim to provide single implementation of this scenario:
mtd_device_parse_register() which will handle all this parsing and
defaults.

As discussed previously, there's the need on some platforms to run some
parts of clk_enable() in contexts which can schedule. The solution
which was agreed upon was to provide clk_prepare() and clk_unprepare()
to contain this parts, while clk_enable() and clk_disable() perform
the atomic part.
This patch provides a common definition for clk_prepare() and
clk_unprepare() in linux/clk.h, and provides an upgrade path for
existing implementation and drivers: drivers can start using
clk_prepare() and clk_unprepare() once this patch is merged without
having to wait for platform support. Platforms can then start to
provide these additional functions.
Eventually, HAVE_CLK_PREPARE will be removed from the kernel, and
everyone will have to provide these new APIs.

Before dma_transfer_direction was introduced to replace
dma_data_direction, some dmaengine device uses DMA_NONE of
dma_data_direction for some talk with its client drivers.
The mxs-dma and its clients mxs-mmc and gpmi-nand are such case.
This patch adds DMA_TRANS_NONE to dma_transfer_direction and
migrate the DMA_NONE use in mxs-dma to it.
It also fixes the compile warning below.

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).
To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.
Hope people are OK with tiny include file.
Note, that mm_types.h is still dragged in, but it is a separate story.

This commit intends to implement the flowchart and details
documented in the HDMI Transmitter Controller User Guide
section entitled "Programming Model".
Some input is also from the Synopsys API code.
The HDMI specification requires HDMI to set itself to VGA DVI mode
before reading the EDID.
So follow this sequence when HDMI is hotplugged:
1. Hdmi connector is plugged in, HDMI video gets an interrupt.
2. Clear out video mode list. Add only VGA DVI mode to list.
3. Request VGA DVI mode (call fb_set_var())
4. HDMI video driver will get FB_EVENT_MODE_CHANGE callback and
call mxc_hdmi_setup() to set up HDMI.
5. Read the edid and add video modes from edid. Select the video
mode that is similar to the command line default.
6. Request VGA DVI mode (call fb_set_var())
7. HDMI video driver will get FB_EVENT_MODE_CHANGE callback and
do mxc_hdmi_setup().
Also included is a workaround for an overflow condition in the HDMI.
The frame composer has an arithmetic unit that gets updated every time
we write to one of the FC registers. But sometimes, depending on the
relation between the tmds and sfr clocks, it may happen that this unit
doesn't get updated, even though the registers are holding correct
values. The workaround for this is, after completing the controller
configuration, to rewrite one of the FC registers (i.e. FC_INVIDCONF)
three or four times with the same value, and then follow it up by a SW
reset to the TMDS clock domain (MC_SWRSTZ).
We clear the overflow condition as described above every time we
change video mode. Also an overflow interupt handler will clear the
overflow condition if it happens again. This overflow condition is
expected (and not a problem) when we are in DVI (non-HDMI) mode, so
we do not worry about it in that case.

- An well-behavior class driver should disable their endpoints
after being notified disconnect with host, we use all endpoints
are stopped (ep->stopped) to indicates the class
driver will not visit device driver any more.
the ep-stopped will be initialized as 1 for non-control endpoint
it will be 0 after fsl_ep_enable, and be 1 after fsl_ep_disable.
Where is a non-sleep wait routine at disconnect event for waiting all
endpoints are stopped
- Some controller's (like i.mx6q) DP will change from J
to SE0 slowly after the cable disconnects with host, in that case there
will be a wakeup interrupt after driver enables the wakeup interrupt.
For i.mx6q, there is a discharge routine for DP after the disconnection.
- Should not wait vbus to low during first otg switch, as the wait will
be timeout when the usb cable is connecting to host.

This new v4l2 output driver is based on videobuf, using dma contig alloc method.
It creates video dev node for each display framebuffer begin from /dev/video16
by default.
If need post-processing, this driver will do it by ipu pp driver which support:
- resizing
- CSC
- rotate
- deinterlacing
If no need post-processing, the IPU IC will be bypassed as old driver, the
buf will be set to fb buffer directly by crack fb smem_start.
The user should do setting before streamon like below:
1. set output crop
2. set ctrl like rotate/vflip/hflip/deinterlacing motion
3. set fmt
4. reqbuf
The new features compare to old driver:
- support multi-instance
- support user point buffer
- runtime suspend/resume
For suspend/resume, still has chance to meet issue on mx6q, will fix later.
