Since the gamma_set_common() function for previous SoC, such as mt8173 and mt8183, is designed for 9bit-to-10bit conversion. mt8195 is using 10bit-to-12bit conversion, which is not compatible with the previous function. Thus, need to update the function to fit the need of mt8195. --- Change in RESEND v3: Fix build warning >> drivers/gpu/drm/mediatek/mtk_disp_gamma.c:59:14: warning: no previous prototype for 'mtk_gamma_get_size' [-Wmissing-prototypes] Change in v3: 1. separate 1 dt-binding patch to 2 patches, 1 is for modifying multiple items list to one and 1 is for moving mt8195 compatible. 2. redefine variables to reduce memory usage. 3. delete unused symbols. 4. separate 1 drm/mediatek patch to 6 patches. 5. rebase on tag 'next-20220909' Jason-JH.Lin (5): drm/mediatek: Adjust mtk_drm_gamma_set_common parameters drm/mediatek: Add gamma support different lut_size for other SoC drm/mediatek: Add gamma support different lut_bits for other SoC drm/mediatek: Add gamma support different bank_size for other SoC drm/mediatek: Add clear RELAY_MODE bit to set gamma zheng-yan.chen (4): dt-bindings: mediatek: modify item formatting for gamma dt-bindings: mediatek: Add gamma compatible for mt8195 drm/mediatek: Add gamma lut support for mt8195 arm64: dts: Modify gamma compatible for mt8195 .../display/mediatek/mediatek,gamma.yaml | 8 +- arch/arm64/boot/dts/mediatek/mt8195.dtsi | 2 +- drivers/gpu/drm/mediatek/mtk_disp_aal.c | 2 +- drivers/gpu/drm/mediatek/mtk_disp_drv.h | 3 +- drivers/gpu/drm/mediatek/mtk_disp_gamma.c | 115 ++++++++++++++---- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 4 +- drivers/gpu/drm/mediatek/mtk_drm_crtc.h | 1 - drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 9 ++ 8 files changed, 109 insertions(+), 35 deletions(-) -- 2.18.0
