Ah thanks, yes I know them. Any other suggestions, of people that might do
OEM design?
thanks

Some rgb-to-vga bridges have an enable GPIO, either directly tied to
an enable pin on the bridge IC, or indirectly controlling a power
switch.
Add support for it.

The A31 TCON has mux controls for how TCON outputs are routed to the
HDMI and MIPI DSI blocks.
Since the A31s does not have MIPI DSI, it only has a mux for the HDMI
controller input.
This patch only adds support for the compatible strings. Actual support
for the mux controls should be added with
Hi everyone,
This series adds support for the first display pipeline found on the
A31 and A31s SoCs, with output through the RGB LCD interface.
This has been tested on the Sinlinx SinA31s development board, with
its included 7" LCD panel, and the Merrii Hummingbird A31 development
board, with its
The LCD0 controller on the A31 can do RGB output up to 8 bits per
channel. Add the pins for RGB888 output.

The Hummingbird A31 board has a RGB-to-VGA bridge which converts RGB
output from the LCD interface to VGA signals.
Enable this part of the display pipeline.

The A31's display pipeline has 2 frontends, 2 backends, and 2 TCONs. It
also has new display enhancement blocks, such as the DRC (Dynamic Range
Controller), the DEU (Display Enhancement Unit), and the CMU (Color
Management Unit). It supports HDMI, MIPI DSI, and 2 LCD/LVDS channels.
The A31s displa
We already have some differences between the 2 supported SoCs.
More will be added as we support other SoCs. To avoid bloating
the probe function with even more conditionals, move the quirks
to a separate data structure that's tied to the compatible string.

The A31 has 2 parallel display pipelines, which can be intermixed.
However the driver currently only supports one of them.

The A31 and A31s also have the DRC as part of the display pipeline.
As we know virtually nothing about them, just add compatible strings
for both SoCs to the stub driver.
