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. --- Base on series [1]: [1]: Add driver nodes for MT8195 SoC - https://patchwork.kernel.org/project/linux-mediatek/list/?series=666741 --- Change in v2: 1. fix global variable in mtk_disp_gamma.c 2. update mask calculation and delete not-necessary variables 3. fix shift-bit problem. 4. fix commit messages for dt-binding 5. fix dts gamma label. zheng-yan.chen (3): 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 | 3 +- 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 | 102 +++++++++++++----- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 5 +- drivers/gpu/drm/mediatek/mtk_drm_crtc.h | 1 - drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.c | 1 + drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 1 + drivers/gpu/drm/mediatek/mtk_drm_drv.c | 2 + 10 files changed, 88 insertions(+), 34 deletions(-) -- 2.18.0
