This series add support for the Topwise A721 tablet and it's display. It is an old tablet (around 2012) but it might be useful as reference as the devicetree is pretty complete.
Pascal Roeleven (2): drm/panel: Add Starry KR070PE2T ARM: dts: sun4i: Add support for Topwise A721 tablet

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.

The binding should be a separate patch. subject - shall start with dt-bindings: Shall be sent to deveicetree mailing list.
For panel we no longer accept .txt bindings. But the good news is that since the panel is simple, you only need to list your compatible in the file bindings/display/panel/panel-simple.yaml - must be en alphabetical order - vendor prefix must be present in vendor-prefixes

For this part specifying the connector type is today mandatory. And please investigate if you can be more precise concerning bus_format, flags, etc. See also what other panels do in the same file.

This one actually looks OK to me. Unless I typoed the numbers the timings give us a vrefresh of 59.58 which gets rounded to 60. So no change once .vrefresh disappears AFAICS.

Hi Sam,
Thank you very much for your review. I did consider this. The reason I combined the patches, is that the binding depends on the display so I thought they were related in some way. Didn't know the correct procedure to handle this. I will split them apart in v2.

Just like Ville Syrjälä, I ran the numbers and vrefresh indeed calculates to 59.58.

FYI, checkpatch.pl will tell you both bindings should be a separate patch and that they should be in DT schema format.

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.
