From: James Ausmus Date: Tue, 30 Jan 2018 11:49:16 -0200 Subject: drm/i915/icl: Handle expanded PLANE_CTL_FORMAT field Git-commit: b597277643fef8f2eab35a6c812b6f98094a0de1 Patch-mainline: v4.17-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 ICL+ adds changes the PLANE_CTL_FORMAT field from [27:24] to [27:23], however, all existing PLANE_CTL_FORMAT_* definitions still map to the correct values. Add an ICL_PLANE_CTL_FORMAT_MASK definition, and use that for masking for the conversion to fourcc. v2: No changes v3: Change new definition name, drop comment (Rodrigo) Cc: Rodrigo Vivi Reviewed-by: Paulo Zanoni Signed-off-by: James Ausmus Signed-off-by: Paulo Zanoni Link: https://patchwork.freedesktop.org/patch/msgid/20180130134918.32283-8-paulo.r.zanoni@intel.com Acked-by: Petr Tesarik --- drivers/gpu/drm/i915/i915_reg.h | 6 ++++++ drivers/gpu/drm/i915/intel_display.c | 5 ++++- 2 files changed, 10 insertions(+), 1 deletion(-) --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -6349,6 +6349,11 @@ enum { #define _PLANE_CTL_3_A 0x70380 #define PLANE_CTL_ENABLE (1 << 31) #define PLANE_CTL_PIPE_GAMMA_ENABLE (1 << 30) /* Pre-GLK */ +/* + * ICL+ uses the same PLANE_CTL_FORMAT bits, but the field definition + * expanded to include bit 23 as well.
