Note that with the current panfrost driver, devfreq is not actually functional, as the we do not have platform-specific support for >1 supplies. Also, we are missing code to handle frequency change, as the GPU frequency needs to be switched away to a stable 26Mhz clock during the transition. 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 v14: - Move gpu_opp_table from soc to root "/" node of dts. Changes in v12: - Add gpu node to mt8183-pumpkin.dts as well (Neil Armstrong). Changes in v11: - mt8183*.dts: remove incorrect supply-names 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 v2: - Use sram instead of mali_sram as SRAM supply name. - Rename mali@ to gpu@. arch/arm64/boot/dts/mediatek/mt8183-evb.dts | 5 + .../arm64/boot/dts/mediatek/mt8183-kukui.dtsi | 5 + .../boot/dts/mediatek/mt8183-pumpkin.dts | 5 + arch/arm64/boot/dts/mediatek/mt8183.dtsi | 105 ++++++++++++++++++ 4 files changed, 120 insertions(+) diff --git a/arch/arm64/boot/dts/mediatek/mt8183-evb.dts b/arch/arm64/boot/dts/mediatek/mt8183-evb.dts index edff1e03e6fe..7bc0a6a7fadf 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-evb.dts +++ b/arch/arm64/boot/dts/mediatek/mt8183-evb.dts @@ -42,6 +42,11 @@ &auxadc { status = "okay"; }; +&gpu { + mali-supply = <&mt6358_vgpu_reg>; + sram-supply = <&mt6358_vsram_gpu_reg>; +}; + &i2c0 { pinctrl-names = "default"; pinctrl-0 = <&i2c_pins_0>; diff --git a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi index ff56bcfa3370..e4e54be1c2b2 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8183-kukui.dtsi @@ -279,6 +279,11 @@ dsi_out: endpoint { }; }; +&gpu { + mali-supply = <&mt6358_vgpu_reg>; + sram-supply = <&mt6358_vsram_gpu_reg>; +}; + &i2c0 { pinctrl-names = "default"; pinctrl-0 = <&i2c0_pins>; diff --git a/arch/arm64/boot/dts/mediatek/mt8183-pumpkin.dts b/arch/arm64/boot/dts/mediatek/mt8183-pumpkin.dts index 0aff5eb52e88..ee912825cfc6 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183-pumpkin.dts +++ b/arch/arm64/boot/dts/mediatek/mt8183-pumpkin.dts @@ -68,6 +68,11 @@ &auxadc { status = "okay"; }; +&gpu { + mali-supply = <&mt6358_vgpu_reg>; + sram-supply = <&mt6358_vsram_gpu_reg>; +}; + &i2c0 { pinctrl-names = "default"; pinctrl-0 = <&i2c_pins_0>; diff --git a/arch/arm64/boot/dts/mediatek/mt8183.dtsi b/arch/arm64/boot/dts/mediatek/mt8183.dtsi index c5e822b6b77a..0afd351f9a9b 100644 --- a/arch/arm64/boot/dts/mediatek/mt8183.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8183.dtsi @@ -197,6 +197,91 @@ CLUSTER_SLEEP1: cluster-sleep-1 { }; }; + gpu_opp_table: opp_table0 { + compatible = "operating-points-v2"; + opp-shared; + + opp-300000000 { + opp-hz = /bits/ 64 <300000000>; + opp-microvolt = <625000>, <850000>; + }; + + opp-320000000 { + opp-hz = /bits/ 64 <320000000>; + opp-microvolt = <631250>, <850000>; + }; + + opp-340000000 { + opp-hz = /bits/ 64 <340000000>; + opp-microvolt = <637500>, <850000>; + }; + + opp-360000000 { + opp-hz = /bits/ 64 <360000000>; + opp-microvolt = <643750>, <850000>; + }; + + opp-380000000 { + opp-hz = /bits/ 64 <380000000>; + opp-microvolt = <650000>, <850000>; + }; + + opp-400000000 { + opp-hz = /bits/ 64 <400000000>; + opp-microvolt = <656250>, <850000>; + }; + + opp-420000000 { + opp-hz = /bits/ 64 <420000000>; + opp-microvolt = <662500>, <850000>; + }; + + opp-460000000 { + opp-hz = /bits/ 64 <460000000>; + opp-microvolt = <675000>, <850000>; + }; + + opp-500000000 { + opp-hz = /bits/ 64 <500000000>; + opp-microvolt = <687500>, <850000>; + }; + + opp-540000000 { + opp-hz = /bits/ 64 <540000000>; + opp-microvolt = <700000>, <850000>; + }; + + opp-580000000 { + opp-hz = /bits/ 64 <580000000>; + opp-microvolt = <712500>, <850000>; + }; + + opp-620000000 { + opp-hz = /bits/ 64 <620000000>; + opp-microvolt = <725000>, <850000>; + }; + + opp-653000000 { + opp-hz = /bits/ 64 <653000000>; + opp-microvolt = <743750>, <850000>; + }; + + opp-698000000 { + opp-hz = /bits/ 64 <698000000>; + opp-microvolt = <768750>, <868750>; + }; + + opp-743000000 { + opp-hz = /bits/ 64 <743000000>; + opp-microvolt = <793750>, <893750>; + }; + + opp-800000000 { + opp-hz = /bits/ 64 <800000000>; + opp-microvolt = <825000>, <925000>; + }; + }; + pmu-a53 { compatible = "arm,cortex-a53-pmu"; interrupt-parent = <&gic>; @@ -1118,6 +1203,26 @@ mfgcfg: syscon@13000000 { #clock-cells = <1>; }; + gpu: gpu@13040000 { + compatible = "mediatek,mt8183-mali", "arm,mali-bifrost"; + reg = <0 0x13040000 0 0x4000>; + interrupts = + , + , + ; + interrupt-names = "job", "mmu", "gpu"; + + clocks = <&topckgen CLK_TOP_MFGPLL_CK>; + + power-domains = + <&spm MT8183_POWER_DOMAIN_MFG_CORE0>, + <&spm MT8183_POWER_DOMAIN_MFG_CORE1>, + <&spm MT8183_POWER_DOMAIN_MFG_2D>; + power-domain-names = "core0", "core1", "core2"; + + operating-points-v2 = <&gpu_opp_table>; + }; + mmsys: syscon@14000000 { compatible = "mediatek,mt8183-mmsys", "syscon"; reg = <0 0x14000000 0 0x1000>;
