Signed-off-by: Nicolas Boichat --- The binding we use with out-of-tree Mali drivers includes more clocks, this is used for devfreq: the out-of-tree driver switches clk_mux to clk_sub_parent (26Mhz), adjusts clk_main_parent, then switches clk_mux back to clk_main_parent: (see https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.19/drivers/gpu/arm/midgard/platform/mediatek/mali_kbase_runtime_pm.c#423) clocks = <&topckgen CLK_TOP_MFGPLL_CK>, <&topckgen CLK_TOP_MUX_MFG>, <&clk26m>, <&mfgcfg CLK_MFG_BG3D>; clock-names = "clk_main_parent", "clk_mux", "clk_sub_parent", "subsys_mfg_cg"; (based on discussions, this probably belongs in the clock core) This only matters for devfreq, that is disabled anyway as we don't have platform-specific code to handle >1 supplies. Changes in v6: - Add gpu regulators to kukui dtsi as well. - Power domains are now attached to spm, not scpsys - Drop R-B. Changes in v5: - Rename "2d" power domain to "core2" (keep R-B again). Changes in v4: - Add power-domain-names to describe the 3 domains. (kept Alyssa's reviewed-by as the change is minor) Changes in v3: - No changes Changes in v2: - Use sram instead of mali_sram as SRAM supply name. - Rename mali@ to gpu@. arch/arm64/boot/dts/mediatek/mt8183-evb.dts | 6 + .../arm64/boot/dts/mediatek/mt8183-kukui.dtsi | 6 + arch/arm64/boot/dts/mediatek/mt8183.dtsi | 105 ++++++++++++++++++ 3 files changed, 117 insertions(+) diff --git a/arch/arm64/boot/dts/mediatek/mt8183-evb.dts b/arch/arm64/boot/dts/mediatek/mt8183-evb.dts index cba2d8933e79..0a8c2fad8e16 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-evb.dts +++ b/arch/arm64/boot/dts/mediatek/mt8183-evb.dts @@ -42,6 +42,12 @@ &auxadc { status = "okay";

Signed-off-by: Nicolas Boichat --- Changes in v6: - Context conflicts, reflow the code. - Use ARRAY_SIZE for power domains too. Changes in v5: - Change power domain name from 2d to core2. Changes in v4: - Add power domain names. Changes in v3: - Match mt8183-mali instead of bifrost, as we require special handling for the 2 regulators and 3 power domains. drivers/gpu/drm/panfrost/panfrost_drv.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/drivers/gpu/drm/panfrost/panfrost_drv.c b/drivers/gpu/drm/panfrost/panfrost_drv.c index 83a461bdeea8..ca07098a6141 100644 --- a/drivers/gpu/drm/panfrost/panfrost_drv.c +++ b/drivers/gpu/drm/panfrost/panfrost_drv.c @@ -665,6 +665,15 @@ static const struct panfrost_compatible amlogic_data = { .vendor_quirk = panfrost_gpu_amlogic_quirk, }; +const char * const mediatek_mt8183_supplies[] = { "mali", "sram" }; +const char * const mediatek_mt8183_pm_domains[] = { "core0", "core1", "core2" }; +static const struct panfrost_compatible mediatek_mt8183_data = { + .num_supplies = ARRAY_SIZE(mediatek_mt8183_supplies), + .supply_names = mediatek_mt8183_supplies, + .num_pm_domains = ARRAY_SIZE(mediatek_mt8183_pm_domains), + .pm_domain_names = mediatek_mt8183_pm_domains, +}; + static const struct of_device_id dt_match[] = { /* Set first to probe before the generic compatibles */ { .compatible = "amlogic,meson-gxm-mali", @@ -681,6 +690,7 @@ static const struct of_device_id dt_match[] = { { .compatible = "arm,mali-t860", .data = &default_data, }, { .compatible = "arm,mali-t880", .data = &default_data, }, { .compatible = "arm,mali-bifrost", .data = &default_data, }, + { .compatible = "mediatek,mt8183-mali", .data = &mediatek_mt8183_data }, {} }; MODULE_DEVICE_TABLE(of, dt_match);
