Also, reduce the LVTS_AP iospace to 0xc00, because that's exactly where SVS starts. - LVTS_AP start: 0x1100b000 length: 0xc00 - SVS start: 0x1100bc00 length: 0x400 Signed-off-by: AngeloGioacchino Del Regno --- arch/arm64/boot/dts/mediatek/mt8195.dtsi | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/mediatek/mt8195.dtsi b/arch/arm64/boot/dts/mediatek/mt8195.dtsi index 54c674c45b49..54debd4cf8e6 100644 --- a/arch/arm64/boot/dts/mediatek/mt8195.dtsi +++ b/arch/arm64/boot/dts/mediatek/mt8195.dtsi @@ -1115,7 +1115,7 @@ spi0: spi@1100a000 { lvts_ap: thermal-sensor@1100b000 { compatible = "mediatek,mt8195-lvts-ap"; - reg = <0 0x1100b000 0 0x1000>; + reg = <0 0x1100b000 0 0xc00>; interrupts = ; clocks = <&infracfg_ao CLK_INFRA_AO_THERM>; resets = <&infracfg_ao MT8195_INFRA_RST0_THERM_CTRL_SWRST>; @@ -1124,6 +1124,18 @@ lvts_ap: thermal-sensor@1100b000 { #thermal-sensor-cells = <1>; }; + svs: svs@1100bc00 { + compatible = "mediatek,mt8195-svs"; + reg = <0 0x1100bc00 0 0x400>; + interrupts = ; + clocks = <&infracfg_ao CLK_INFRA_AO_THERM>; + clock-names = "main"; + nvmem-cells = <&svs_calib_data &lvts_efuse_data1>; + nvmem-cell-names = "svs-calibration-data", "t-calibration-data"; + resets = <&infracfg_ao MT8195_INFRA_RST3_THERM_CTRL_PTP_SWRST>; + reset-names = "svs_rst"; + }; + disp_pwm0: pwm@1100e000 { compatible = "mediatek,mt8195-disp-pwm", "mediatek,mt8183-disp-pwm"; reg = <0 0x1100e000 0 0x1000>; @@ -1682,6 +1694,9 @@ lvts_efuse_data1: lvts1-calib@1bc { lvts_efuse_data2: lvts2-calib@1d0 { reg = <0x1d0 0x38>; }; + svs_calib_data: svs-calib@580 { + reg = <0x580 0x64>; + }; }; u3phy2: t-phy@11c40000 {
