For the PVS_SLOW the pvs_tables doesn't list turbo boost, so all three voltages are the same. > > + opp-microvolt-speed0-pvs1 = <925000 900000 950000>; This comes from acpu_freq_tbl_nom. The voltage from the table becomes the middle value (min). For PVS_NOM the pvs_tables has the turbo value (25000), which acpuclock-krait applied by default, this becomes the first (target) value. For maximum I added another 25 mV to account for this exact value not being supported by the core (SAW) regulator. > > + opp-microvolt-speed0-pvs3 = <875000 850000 900000>; > > + opp-supported-hw = <0x1>; > > + /* > > + * higher latency as it requires switching between > > + * clock sources > > + */ > > + clock-latency-ns = <244144>; > > + }; > > + > > + opp-486000000 { > > + opp-hz = /bits/ 64 <486000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <975000 975000 975000>; > > + opp-microvolt-speed0-pvs1 = <950000 925000 975000>; > > + opp-microvolt-speed0-pvs3 = <900000 875000 925000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-594000000 { > > + opp-hz = /bits/ 64 <594000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <1000000 1000000 1000000>; > > + opp-microvolt-speed0-pvs1 = <975000 950000 1000000>; > > + opp-microvolt-speed0-pvs3 = <925000 900000 950000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-702000000 { > > + opp-hz = /bits/ 64 <702000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <1025000 1025000 1025000>; > > + opp-microvolt-speed0-pvs1 = <1000000 975000 1025000>; > > + opp-microvolt-speed0-pvs3 = <950000 925000 975000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-810000000 { > > + opp-hz = /bits/ 64 <810000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <1075000 1075000 1075000>; > > + opp-microvolt-speed0-pvs1 = <1050000 1025000 1075000>; > > + opp-microvolt-speed0-pvs3 = <1000000 975000 1025000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-918000000 { > > + opp-hz = /bits/ 64 <918000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <1100000 1100000 1100000>; > > + opp-microvolt-speed0-pvs1 = <1075000 1050000 1100000>; > > + opp-microvolt-speed0-pvs3 = <1025000 1000000 1050000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1026000000 { > > + opp-hz = /bits/ 64 <1026000000>; > > + opp-peak-kBps = <702000>; > > + opp-microvolt-speed0-pvs0 = <1125000 1125000 1125000>; > > + opp-microvolt-speed0-pvs1 = <1100000 1075000 1125000>; > > + opp-microvolt-speed0-pvs3 = <1050000 1025000 1075000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1134000000 { > > + opp-hz = /bits/ 64 <1134000000>; > > + opp-peak-kBps = <1350000>; > > + opp-microvolt-speed0-pvs0 = <1175000 1175000 1175000>; > > + opp-microvolt-speed0-pvs1 = <1150000 1125000 1175000>; > > + opp-microvolt-speed0-pvs3 = <1100000 1075000 1125000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1242000000 { > > + opp-hz = /bits/ 64 <1242000000>; > > + opp-peak-kBps = <1350000>; > > + opp-microvolt-speed0-pvs0 = <1200000 1200000 1200000>; > > + opp-microvolt-speed0-pvs1 = <1175000 1150000 1200000>; > > + opp-microvolt-speed0-pvs3 = <1125000 1100000 1150000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1350000000 { > > + opp-hz = /bits/ 64 <1350000000>; > > + opp-peak-kBps = <1350000>; > > + opp-microvolt-speed0-pvs0 = <1225000 1225000 1225000>; > > + opp-microvolt-speed0-pvs1 = <1200000 1175000 1225000>; > > + opp-microvolt-speed0-pvs3 = <1150000 1125000 1175000>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1458000000 { > > + opp-hz = /bits/ 64 <1458000000>; > > + opp-peak-kBps = <1350000>; > > + opp-microvolt-speed0-pvs0 = <1237500 1237500 1237500>; > > + opp-microvolt-speed0-pvs1 = <1212500 1187500 1237500>; > > + opp-microvolt-speed0-pvs3 = <1162500 1137500 1187500>; > > + opp-supported-hw = <0x1>; > > + }; > > + > > + opp-1512000000 { > > + opp-hz = /bits/ 64 <1512000000>; > > + opp-peak-kBps = <1350000>; > > + opp-microvolt-speed0-pvs0 = <1250000 1250000 1250000>; > > + opp-microvolt-speed0-pvs1 = <1225000 1200000 1250000>; > > + opp-microvolt-speed0-pvs3 = <1175000 1150000 1200000>; > > + opp-supported-hw = <0x1>; > > + }; > > + }; > > + > > memory { > > device_type = "memory"; > > reg = <0x0 0x0>; > > @@ -266,6 +402,17 @@ msmgpio: pinctrl@800000 { > > reg = <0x800000 0x4000>; > > }; > > > > + qfprom: qfprom@700000 { > > + compatible = "qcom,msm8960-qfprom", "qcom,qfprom"; > > + reg = <0x00700000 0x1000>; > > + #address-cells = <1>; > > + #size-cells = <1>; > > + ranges; > > + speedbin_efuse: speedbin@c0 { > > + reg = <0x0c0 0x4>; > > + }; > > + }; > > + > > gcc: clock-controller@900000 { > > compatible = "qcom,gcc-msm8960"; > > #clock-cells = <1>; -- With best wishes Dmitry
