From b3e0b2dba870cc2f1d614a0f04459c18d8bf71a3 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Thu, 20 Oct 2016 11:43:38 +0800 Subject: [PATCH] drm/sun4i: sun6i-drc: Support DRC on A31 and A31s The A31 and A31s also have the DRC as part of the display pipeline. As we know virtually nothing about them, just add compatible strings for both SoCs to the stub driver.
