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.
Changes from v1: * Split into multiple patches * dt-binding: use yaml instead of txt * dt-binding: add Topwise A721 to sunxi.yaml * dt-binding: add Topwise to vendor-prefixes * drm: Add bus_format, bus_flags and connector_type * dts: Use SPDX license identifier instead of boilerplate license text * dts: Remove pinctrl leftovers

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.

I'm trying to fix inconsistencies in the panel-simple driver, and this caught my eyes. MEDIA_BUS_FMT_RGB888_1X24 isn't a correct format for LVDS panels. MEDIA_BUS_FMT_RGB666_1X7X3_SPWG, MEDIA_BUS_FMT_RGB888_1X7X4_SPWG or MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA should be used instead. As I couldn't find documentation for the panel, I can't tell which format is correct. Could you please help ?

Hi Laurent,
Good catch. It's actually the connector type which is wrong. The connector_type should be DRM_MODE_CONNECTOR_DPI. If you would include this in your patch series, you can have my acked-by.

It looks good to me for the last 2 patches, I'll wait for feedback from Thierry or Sam on the panel side.
