Very nice to see the progress! Thank you very much!
Hello! This series adds support for display panel's DT rotation property. It's a continuation of the work that was initially started by Derek Basehore for the panel driver that is used by some Mediatek device [1]. I picked up the Derek's patches and added my t-b and r-b tags to them, I also added rotation support to the panel-lvds and panel-simple drivers. We need the rotation support for the Nexus 7 tablet device which is now supported by the upstream kernel, the device has display panel mounted upside-down and it uses panel-lvds [2].

The v11 missed v5.9 release, re-sending patches for the v5.10 kernel. Please review and apply patches to linux-next, thanks in advance! v11: - This series is factored out from this patchset [3] because these patches do not have hard dependency on the Tegra DRM patches and it should be nicer to review and apply the properly grouped patches. - Initially [3] only touched the panel-lvds driver and Emil Velikov suggested that it will be better to support more panels in the review comments to [3]. So I included the Derek's patch for the BOE panel and added rotation support to the panel-simple driver. I tested that panel-lvds and panel-simple work properly with the rotated panel using the Opentegra Xorg driver [4] and Wayland Weston [5]. - The panel-lvds driver now prints a error message if rotation property fails to be parsed.
