[PATCH 0/5] arm64: dts: add rk3399 display-related nodes

[Jacob Chen]

This series patches add the display-related nodes for rk3399.

Tested with kernel base on drm-misc and below patches.
https://cgit.freedesktop.org/drm/drm-misc/
"drm: bridge: synopsys/dw-hdmi: Provide default configuration function for HDMI 2.0 PHY"
"iommu/rockchip: Enable Rockchip IOMMU on ARM64"

HDMI could work and have a display output.
eDP could link with panel but i didn't get a display(Maybe something wrong in power things).

For convenience, i think we should have those nodes in kernel now.

[PATCH 1/5] arm64: dts: rockchip: Add rk3399 vop and display-subsystem

[Jacob Chen]

Add devicetree nodes for rk3399 VOP (Video Output Processors), and the
top level display-subsystem root node.

Later patches add endpoints (eDP, HDMI, MIPI, etc) that attach to the
VOPs' output ports.

What is this second memory region doing? It looks like this is the meant
to cover VOP_GAMMA_LUT_ADDR, but can't you just map the whole area?
ChromeOS seems to be doing fine using the whole area as
	<0x0 0xff8f0000 0x0 0x3efc>
and I've also not seen any code changes actually mapping/using this
second area.

While I know that this is based on my idea on handling the hdmi pll-rate
requirements, I haven't found the matching code- and dt-binding-changes
posted to a list yet.

0x1c00 - 0x200 for cabc_lut
0x2000 - 0x300 for gama_lut

My mistakes, It seems mark havn't send gamma and cabc support to upstream.
We shoud just using the whole area map.

As we don't know how much discussion is necessary for that, removing
dclk_source in the first iteration and re-add it once the feature.

you might want to reduce the number of Signed-offs a bit :-)

Also authorship needs to be fixed. I.e. first Signed-off for this patch
is from Mark, so in that case Mark probably also was the original author
and the patch should reflect that. General rule, topmost Signed-off is
of course from the original author.
