From: Laurent Pinchart Date: Sat, 24 Nov 2018 17:57:17 +0000 (+0200) Subject: drm: rcar-du: Replace EXT_CTRL_REGS feature flag with generation check X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cef0d9cfe4e5b6c756c268c1b7dda7fa257336fc;p=openwrt%2Fstaging%2Fblogic.git drm: rcar-du: Replace EXT_CTRL_REGS feature flag with generation check The RCAR_DU_FEATURE_EXT_CTRL_REGS feature flag is missing for H1 only, which is a first generation device, not a second generation device as reported in the device information table. Fix the H1 generation and use generation checks to replace the feature flag.
