Sun, 27 Oct 2024 23:42:05 +0000

drm/panel: samsung-s6e88a0-ams427ap24: Add brightness controlThe tables for brightness to candela, aid and elvss were taken from downstreamkernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [1][2][3].The gamma table gets generated in "ss_dsi_smart_dimming_S6E88A0_AMS427AP24.c" [4]with hard-coded starting values. The function smart_dimming_init() [5] goesthrough the v{*}_adjustments, generate_gray_scale and gamma_init procedure.Instead of calculating it manually, it's easier to compile a custom downstreamkernel with SMART_DIMMING_DEBUG enabled and read out dmesg early at boot.Selection of the values for aid and elvss are again according to downstreamfile "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [6][7].The set of write commands is guided by downstream file "ss_dsi_panel_common.c" [8]followed by "ss_dsi_panel_S6E88A0_AMS427AP24.c" [9].The dsi mode flag MIPI_DSI_MODE_VIDEO_NO_HFP prevents screen flickering whilechanging the brightness.[1] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi#L341-L397[2] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi#L214-L254[3] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi#L301-L320[4] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/ss_dsi_smart_dimming_S6E88A0_AMS427AP24.c[5] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/ss_dsi_smart_dimming_S6E88A0_AMS427AP24.c#L1816-L1900[6] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi#L256-L268[7] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi#L322-L334[8] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/ss_dsi_panel_common.c#L1389-L1517[9] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/ss_dsi_panel_S6E88A0_AMS427AP24.c#L666-L678Signed-off-by: Jakob Hauser Reviewed-by: Neil Armstrong Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/30c154954a4e0f75d90f6ef6f393a5ba8b3ffea9.1730070570.git.jahau@rocketmail.comSigned-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/30c154954a4e0f75d90f6ef6f393a5ba8b3ffea9.1730070570.git.jahau@rocketmail.com List of files: /linux-6.15/drivers/gpu/drm/panel/Kconfig

drm/panel: samsung-s6e88a0-ams427ap24: Add initial driverThis initial part of the panel driver was mostly generated by the"linux-mdss-dsi-panel-driver-generator" tool [1], reading downstreamAndroid kernel file "dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsi" [2].On top of the generic output of the tool, there were a couple of changesapplied:- Added mipi_dsi_dcs_set_display_on() to function s6e88a0_ams427ap24_on(), otherwise the display does not show up.- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() changed DSI commands to multi context and used "accum_err" returns.- In functions s6e88a0_ams427ap24_on() and s6e88a0_ams427ap24_off() replaced msleep() by mipi_dsi_msleep().- The function s6e88a0_ams427ap24_get_modes() was changed to make use of drm_connector_helper_get_modes_fixed(). This also required to include drm/drm_probe_helper.h.- In function s6e88a0_ams427ap24_probe() registring the regulators was changed to devm_regulator_bulk_get_const(). This required to change supplies in struct s6e88a0_ams427ap24 to a pointer.- Removed bool "prepared" from struct s6e88a0_ams427ap24 and according parts in functions s6e88a0_ams427ap24_prepare() and s6e88a0_ams427ap24_unprepare().- Removed include , it's not needed.- Added comments to the mipi_dsi_dcs_write_seq_multi() lines in function s6e88a0_ams427ap24_on().[1] https://github.com/msm8916-mainline/linux-mdss-dsi-panel-driver-generator[2] https://github.com/msm8916-mainline/linux-downstream/blob/GT-I9195I/drivers/video/msm/mdss/samsung/S6E88A0_AMS427AP24/dsi_panel_S6E88A0_AMS427AP24_qhd_octa_video.dtsiSigned-off-by: Jakob Hauser Reviewed-by: Linus Walleij Link: https://lore.kernel.org/r/d92ef0036b66520bb6d1ec908165e776cf30c303.1730070570.git.jahau@rocketmail.comSigned-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/d92ef0036b66520bb6d1ec908165e776cf30c303.1730070570.git.jahau@rocketmail.com List of files: /linux-6.15/drivers/gpu/drm/panel/Kconfig
