During hdmi hotplug test, there's a possibility that X-server unblanks
the frame buffer while HDMI-audio just gets the signal to start playback.
Then audio would get an unblanked state right before the playback and
bypassed the DMA enabling code. So this issue is caused by the race
between unblank and set_cable_state().
This patch sets the hdmi cable state a bit earilier so as to let audio
play first. If unblank happens later, the hdmi core and hdmi audio would
be robust enough to handle that case as long as it's not racing with the
other parts.

This issue happens when multiple thread is trying to idle GPU at the
same time, root cause is some wrong logic related with powerMutex which
cause cpu still access GPU AHB register after GPU is suspend(clock off),
that cause the bus lockup and make the whole system hang.

The mipi csi2 code is ugly present in the capture pipeline setup/disable
routions with '#ifdef CONFIG_MXC_MIPI_CSI2/#endif' protected. Whenever
it finds mipi_csi2_info is not gotten correctly, it will return error to
callers. This breaks the normally routines in which mipi csi2 is not used
and mipi csi2 driver is disabled in its devicetree node(but with the
Kconfig CONFIG_MXC_MIPI_CSI2 defined). A real example is the capture
feature on the MX6 Sabreauto platforms. We have only parallel CSI input
on it and the mipi csi2 driver is disabled in its devicetree node but with
the Kconfig CONFIG_MXC_MIPI_CSI2 defined. So, a reasonable choice at present
is not to return error if mipi_csi2_info cannot be gotten, though we could
eventually re-organize the capture code for a better total solution in the
future.

commit f8e1a3bb62eecf93a31a51c4dbe08a0214fa1d57 added a hard
coding for csi_parma.mclk setting to 27MHz. The comment added by
that commit is totally wrong by telling that csi_param.mclk
would be a kind of 'pixel clock' set in 'csi_data_dest' register.
This patch removes the unnecessary mclk setting for csi_param.mclk

so HDMI driver will create a default support mode list when system

Because yocto xserver can not get video mode information from
framebuffer now, and xserver will set default video mode XGA
to framebuffer, but XGA mode is not support by hdmi.
Remove XGA and SXGA from default support list.
HDMI driver will find a nearest match video mode in support list.

We have met a bug that the high bandwidth ISO-TX transfer has failed
at the last packet if it is less than 1024, the TD status shows it
is "Transaction Error".
The root cause of this problem is: the mult value at qh is not correct
for current TD's transfer length. We use TD list to queue un-transfer
TDs, and change mult for new adding TDs. If new adding TDs transfer length
less than 1024, but the queued un-transfer TDs transfer length is larger
than 1024, the transfer error will occur, and vice versa.
Usually, this problem occurs at the last packet, and the first packet for
new frame.
We fixed this problem by setting Mult at QH as the largest value (3), and
set MultO (Multiplier Override) at TD according to every transfer length.
It can cover both hardware version less than 2.3 (the real mult is MultO
if it is not 0) and 2.3+ (the real mult is min(qh.mult, td.multo)).
Since the MultO bits are only existed at TX TD, we keep the ISO-RX behavior
unchanged.
For stable tree: 3.11+.
