[PATCH 0/7] drm/panel: sitronix-st7789v: Support ET028013DMA panel

[Miquel Raynal]

Hello,

The aim of this series is to add support for the EDT ET028013DMA
panel. This panel features a Sitronix ST7789V2 LCD controller, which is
already supported mainline (or very close to the ST7789V for which
Maxime added support years ago).

The EDT panel is slightly different on the geometry and appears not to
support refresh rates higher than 30fps (above, glitches are visible,
despite the incoming signals being rather clean). While I was working on
this panel, I found quite inconvenient to not be able to read anything
back as it is a great tool for debugging purposes. So the last patch
actually adds a read helper and uses it to perform a sanity check at
probe time by verifying the Sitronix controller IDs. If deemed
irrelevant, this patch may be discarded.

Thanks,
Miquèl
