Allwinner V3s SoC features two CSI module. CSI0 is used for MIPI CSI-2
interface and CSI1 is used for parallel interface. This is not
documented in datasheet but by test and guess.
This patch implement a v4l2 framework driver for it.
Currently, the driver only support the parallel interface. MIPI
As DE2 support for more SoCs are introducing, there's many reports that
the DE2 is not functional due to DE2 CCU code not included in kernel.
Defaultly enable DE2 CCU for sun8i/sun50i to reduce this kind of
problems.

This commit adds all necessary compatibles and descriptions needed to
implement A83T HDMI pipeline.
Mixer is already properly described, so only compatible is added.
However, A83T TV TCON, which is connected to HDMI, doesn't have channel 0,
contrary to all TCONs currently described. Because of th
This TCON is connected to HDMI encoder.

A83T has DW HDMI IP block with a custom PHY similar to Synopsys gen2
HDMI PHY.
Only video output was tested, while HW also supports audio and CEC.
Support for them will be added later.

This commit changes formula from this:
Freq = (parent_freq * N * K) / (M * P)
to this:
Freq = (parent_freq / M) * N * K / P
This improves situation when N is in the range 1-255. PLL parent clock
is almost always 24 MHz, which means that for N >= 180 original formula
overflows and result becomes
It supports 1 VI and 1 UI plane and HW scaling on both planes.

Some TCONs on newer SoCs doesn't support channel 0, since they are meant
to be used only with TV or HDMI encoder.
Prepare support for them with adding has_channel_0 quirk.

Parts of PHY code could be useful also for custom PHYs. For example,
Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY
with few additional memory mapped registers, so most of the Synopsys PHY
related code could be reused.

Some SoCs, like Allwinner A83T, have to do additional cleanup when

no place to store driver's private data so it can be accessed in unbind

Currently, if one of the factors isn't present, bit 0 gets always set to
1. For example, A83T has NMP PLLs modelled as NKMP PLL without K. Since
K is not specified, it's offset, width and shift is 0. Driver assumes
that lowest value possible is 1, otherwise we would get division by 0.

Allwinner SoCs have dw hdmi controller v1.32a which exhibits same

This patch series implements support for A83T DW HDMI and PHY. Contrary to
v1 series, this one is based on latest linux-next, since all needed patches
were merged.
While exactly this combination of HDMI controller and PHY is not common in
Allwinner SoCs, this patch series nevertheless makes ground
