Subject: [PATCH 00/15] Support more HDMI modes on RK3228/RK3328

This series make it possible to use more HDMI modes on RK3328,
and presumably also on RK3228. It also prepares for a future YUV420 and
10-bit output series.

Part of this has been reworked from vendor BSP 4.4 kernel commits.

Patch 1-5 fixes issues and shortcomings in the inno hdmi phy driver.

Patch 6 filter out any mode having larger width then 3840 pixels,
e.g 4096x2304 modes, since limitations in the scaler code trigger an error
for a large console framebuffer.

Patch 7 prepares for use of high TMDS bit rates used with HDMI2.0 and
10-bit output modes.

Patch 8-14 changes rk3228/rk3328 to use mode_valid functions suited for
the inno hdmi phy instead of the dw-hdmi phy. This

Patch 15 adds support for more pixel clock rates in order to support
common DMT modes in addition to CEA modes.

Note: I have only been able to build test RK322x related changes
as I do not have any RK322x device to test on.

All modes, including fractal modes, has been tested with modetest on
a RK3328 Rock64 device.

  modetest -M rockchip -s 39:3840x2160-29.97

Regards,
Jonas
