From d2ac235d446aa87dbe2bbb3883b8707ae43f3e6d Mon Sep 17 00:00:00 2001 From: Khang Nguyen Date: Fri, 3 Apr 2020 16:57:36 +0900 Subject: rcar-gen3: linux-renesas: Fix ZPOS issue occurs on Weston 8.0.0 This applies a patch to Kernel to fix ZPOS issue occurs on Weston 8.0.0: According to drm_plane_create_zpos_property() function documentation, all planes zpos range should be set if zpos property is supported. However, the rcar-du driver didn't set primary plane zpos range. Since the primary plane's zpos is fixed, set it immutably.
