On request I'm resending the last two patches from the Topwise A721 tablet
series from a year ago as they weren't picked up. The other patches are
already merged, so I didn't resend them.
Changes from v3:
* Fix DT validation warnings
* Remove leftover labels
Changes from v2:
* Collected acked-by.
Original cover letter:
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 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.
