This is a note to let you know that I've just added the patch titled ARM: dts: logicpd-som-lv-baseboard: Fix missing video to the 5.8-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-dts-logicpd-som-lv-baseboard-fix-missing-video.patch and it can be found in the queue-5.8 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 785855caf7f152ac0441dd18cfe7e9ec4ae23584 Author: Adam Ford <aford173@xxxxxxxxx> Date: Fri Aug 14 07:24:41 2020 -0500 ARM: dts: logicpd-som-lv-baseboard: Fix missing video [ Upstream commit d1db7b80a6c8c5f81db0e80664d29b374750e2c6 ] A previous commit removed the panel-dpi driver, which made the SOM-LV video stop working because it relied on the DPI driver for setting video timings. Now that the simple-panel driver is available in omap2plus, this patch migrates the SOM-LV dev kits to use a similar panel and remove the manual timing requirements. A similar patch was already done and applied to the Torpedo family.
