From: Maxime Ripard Date: Tue, 28 Jul 2020 13:48:10 +0000 (+0200) Subject: drm/sun4i: backend: Disable alpha on the lowest plane on the A20 X-Git-Tag: v5.4.66~105 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=c46eabd1e6cc51f5a891b043843f502f4acb87cf;p=users%2Fdwmw2%2Flinux.git drm/sun4i: backend: Disable alpha on the lowest plane on the A20 [ Upstream commit 5e2e2600a3744491a8b49b92597c13b693692082 ] Unlike we previously thought, the per-pixel alpha is just as broken on the A20 as it is on the A10. Remove the quirk that says we can use it.
