Does anyone have any comments to this patchset? Will be nice if it could get into 5.9 :) Thanks in advance!
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 pending to become supported by upstream kernel, the device has display panel mounted upside-down and it uses panel-lvds [2].

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.
