f4a6de855e drm: rockchip: vop: add rk3066 vop definitions
This patch adds the rk3066 VOP definitions.

The VOP or LCD Controller serves as interface between
framebuffer memory and a display device (LCD panel or TV set).

This SOC has two symmetrical LCDC's for a dual panel application.

A LCDC has 5 display layers.
Only 3 are used here.

- Video layer 0 (Win0)
- Video layer 1 (Win1)
- OSD layer     (Win2)

Win0 and Win1 are exchangeable.
Maximum resolution is 1920x1080.

The LCDC0 output is connected to:
- LCDC0 IO (without IOMUX)
- HDMI TX video input

The LCDC1 output is connected to:
- LCDC1 IO (with IOMUX)
- HDMI TX video input

The HDMI TX input can switch between LCDC0 and LCDC1.

677e8bbc0e drm/rockchip: Add reflection properties
Add the KMS plane rotation property to the DRM rockchip driver,
for SoCs RK3328, RK3368 and RK3399.

RK3288 only supports rotation at the display level (i.e. CRTC),
but for now we are only interested in plane rotation.

This commit only adds support for the value of reflect-y
and reflect-x (i.e. mirroring).

Note that y-mirroring is not compatible with YUV.

The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.

X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17

Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33

XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49

fbb1c73826 drm/rockchip: Separate RK3288 from RK3368 win01 registers
This commit splits the registers for RK3288 from those
for RK3328, RK3368 and RK3399. It seems RK3288 does not
support plane x-y-mirroring, and so in order to support this
for the other SoCs, we need to have separate set of registers
for win0 and win1.

1c21aa8f2b drm/rockchip: Fix YUV buffers color rendering
Currently, YUV hardware overlays are converted to RGB using
a color space conversion different than BT.601.

The result is that colors of e.g. NV12 buffers don't match
colors of YUV hardware overlays.

In order to fix this, enable YUV2YUV and set appropriate coefficients
for formats such as NV12 to be displayed correctly.

This commit was tested using modetest, gstreamer and chromeos (hardware
accelerated video playback). Before the commit, tests rendering
with NV12 format resulted in colors not displayed correctly.

Test examples (Tested on RK3399 and RK3288 boards
connected to HDMI monitor):

  $ modetest 39@32:1920x1080@NV12
  $ gst-launch-1.0 videotestrc ! video/x-raw,format=NV12 ! kmssink

cf6d100dd2 drm/rockchip: dsi: add dual mipi support
Add the Rockchip-sepcific dual-dsi setup and hook it into the VOP as well.
As described in the general dual-dsi devicetree binding, the panel should
define two input ports and point each of them to one of the used dsi-
controllers, as well as declare one of them as clock-master.
This is used to determine the dual-dsi state and get access to both
controller instances.

v6:
  handle master+slave component in dsi-attach
v5:
  use driver-internal mechanism to find dual dsi slave
v4:
  add component directly in probe when adding empty dsi slave controller

The hs_start interrupt on rk3188 fires at the start of a new frame, so
serves essentially the same purpose as the dsp_hold_valid irq in checking
when the last frame got delivered when going to standby. So define it
to fix a hang on atomic_disable of the vop because the completion never
really completed before.

6bda8112fe drm/rockchip: pre dither down when output bpc is 8bit
Some encoder have a crc verification check, crc check fail if
input and output data is not equal.

That means encoder input and output need use same color depth,
vop can output 10bit data to encoder, but some panel only support
8bit depth, that would make crc check die.

So pre dither down vop data to 8bit if panel's bpc is 8.

EDP, HDMI, DisplayPort all have 10bit input on rk3399,
On non-10bit vop, vop 8bit output bit[0-7] connect to the
encoder high 8bit [2-9].

So force RGB10 to RGB888 on vop driver would be better.

And another problem, EDP check crtc id on atomic_check,
but encoder maybe NULL, so out_mode configure would fail,
it cause edp no display.

VOP have integrated a hardware counter which indicate the exact display
line that vop is scanning. And if we're interested in a specific line,
we can set the line number to vop line_flag register, and then vop would
generate a line_flag interrupt for it.

For example eDP PSR function is interested in the vertical blanking
period, then driver could set the line number to zero.

This patch have exported a symbol that allow other driver to listen the
line flag event with given timeout limit:
