This applies to HDMI-map register 0x69.
So far we have been using HPA manual mode.
This way we had control of HPA which could be
set after EDID had been programmed.

Using a Mac Mini with mini-displayport to DVI-D converter as source
caused the adv7842 to lock up and fail to detect any further signals.

After experimenting with different configurations it was found that
using the HPA auto mode and in addition letting RX-termination
be controlled by HPA prevented this error from occuring.

I was not able to re-create this problem on the adv7604.

If the input signal is DVI-D and quantization range is RGB full range,
gain and offset must be adjusted to get the right range on the output.

The STDI block may measure wrong values, especially for lcvs and lcf.
If the driver can not find any valid timing, the STDI block is restarted
to measure the video timings again. The function will return an error,
but the restart of STDI will generate a new STDI interrupt and the format
detection process will restart.

Both the PAL and NTSC standards are interlaced where a
frame consist of two fields. Total number of lines in a frame in both systems
are an odd number so the two fields will have different length.

In the 625 line standard ("PAL") the odd field of the frame is transmitted first,
while in the 525 standard ("NTSC") the even field is transmitted first.

This adds the possibility to change output config between the fields and standards.

This setting will reduce the "format-jitter" on the signal sent by the pixelport
moving the difference between the fields to vertical front/back-porch only.

Added support for YCrCb analog input.

If input is ADV7842_MODE_RGB and RGB quantization range is set to
V4L2_DV_RGB_RANGE_AUTO, then video with CEA timings will be received
as RGB. For ADV7842_MODE_COMP, automatic CSC mode will be selected.

See table 48 on page 281 in "ADV7842 Hardware Manual, Rev. 0, January 2011"
for details.

Make sure that when switching inputs the RGB quantization range is
updated as well.

Also updated the platform_data in ezkit to ensure that what was the old
default value is now explicitly specified, so the behavior for that board
is unchanged.

The method of disabling the irq-output pin caused many "empty"
interrupts. Instead, actually disable/enable the interrupts by
changing the interrupt masks.

Also enable STORE_MASKED_IRQ in INT1 configuration, otherwise when HDMI
events happen while the interrupt is masked those events will be ignored
when the interrupt is unmasked.
