[linux-sunxi] [PATCH v2 5/5] ARM: dts: sun4i: Add support for Topwise A721 tablet
The Topwise A721/LY-F1 tablet is a tablet sold around 2012 under
different brands. The mainboard mentions A721 clearly, so this tablet
is best known under this name.

[linux-sunxi] [PATCH v2 2/5] drm: panel: Add Starry KR070PE2T
The KR070PE2T is a 7" panel with a resolution of 800x480.
KR070PE2T is the marking present on the ribbon cable. As this panel is
probably available under different brands, this marking will catch
most devices.
As I can't find a datasheet for this panel, the bus_flags are instead
from trial-and-error. The flags seem to be common for these kind of
panels as well.

So following up on this: We should state in the commit message that this driver is for all displays using the Sitronix ST770x display controllers. The driver should be named panel-sitronix-st770x.c.

Heh, I wonder how it comes that it is so similar to Ilitek. I guess I will never understand how the silicon ecosystem works in asia (I did read a lot of Bunnie Huang's articles and hardware hacking book to try to understand...) This file should be named sitronix,st7703.yaml then. According to the code in the Librem 5: https://source.puri.sm/Librem5/linux-next/blob/imx8-current-librem5/drivers/gpu/drm/panel/panel-sitronix-st7701.c The actual name of the display is Techstar ts8550b. And the display controller is st7701, so maybe we should actually name it sitronix,st770x.yaml if there are some sub-variants of st770x? > >properties: > > compatible: > >items: > > - const: xingbangda,xbd599 > > - const: ilitek,ili9342 > > > >Possibly use oneOf and add support for the himax,hx8363 > >already while you're at it. This should at least be: compatible: items: - enum: - xingbangda,xbd599 - himax,hx8363 - techstar,ts8550b - enum: - sitronix,st7701 - sitronix,st7703 So panel nodes using this panel become compatible = "xingbangda,sbd599", "sitronix,st7703" etc. This way it is straight-forward for drivers to identify the panel vendor and display controller.
