0eebd421ac dt-bindings: display: bridge: simple: document the ASL CS5263 DP-to-HDMI bridge 
The ASL CS5263 is a high-performance DP1.4 to HDMI2.0b converter,
designed to connect a DP1.4 source to an HDMI2.0b sink. The CS5263AN
integrates a DP1.4 compliant receiver, and a HDMI2.0b compliant
transmitter.

1388c08c84 dt-bindings: panel: Convert Samsung SOFEF00 DDIC into standalone yaml 
Reason for moving from simple panel is this DDIC has three supplies,
while panel-simple-dsi is limited to one.

Previous compatible only described the DDIC, but didn't include panel
connected to it. Let's fix it, and offer bindings authors two
compatibles to distinguish the connected panel.

Basic description for SOFEF00 DDIC with attached panels

 - Samsung AMS601NT22 6.01 inch, 1080x2160 pixels, 18:9 ratio
 - Samsung AMS628NW01 6.28 inch, 1080x2280 pixels, 19:9 ratio

There is only one user which uses samsung,sofef00 and it's updated to
comply within this patch series.

88a1885979 dt-bindings: display: panel: properly document LG LD070WX3 panel 
LG LD070WX3-SL01 was mistakenly documented as a simple DSI panel, which it
clearly is not. Address this by adding the proper schema for this panel.

There is only one user of this panel binding in the mainline Linux kernel,
which is the Nvidia tablet Tegra Note 7. Its panel is broken anyway since
it cannot initialize properly if the bootloader does not leave a
pre-initialized panel. It also cannot suspend or re-initialize properly,
since no DSI configuration is set and it has a loose regulator which
relies on an always-on property rather than being hooked to the panel
where it belongs.

Tegra Note 7 device tree is adjusted as a part of this series.

This allows the allOf section to limit various GPU models to
matching clocks count in the first half, and apply the same
for power-domains count in the second half, without conflating
the two limits together.

This makes addition of GPU models with different clocks and
