Hello,
we are using DRA714 SOC for our board which requires Frequency scaling support.
As per the datasheet, the maximum frequency supported for MPU is 600 Mhz.
In the kernel code in arch/arm/boot/dts/dra7.dtsi the OPP values configured are as from Automotive Processor SDK 3.03.
cpu0_opp_table: opp_table0 {
compatible = "operating-points-v2";
opp-shared;
opp_nom@1000000000 {
opp-hz = /bits/ 64 <1000000000>;
opp-microvolt = <1060000 850000 1150000>;
opp-supported-hw = <0xFF 0x01>;
opp-suspend;
};
opp_od@1176000000 {
opp-hz = /bits/ 64 <1176000000>;
opp-microvolt = <1160000 885000 1160000>;
opp-supported-hw = <0xFF 0x02>;
};
opp_high@1500000000 {
opp-hz = /bits/ 64 <1500000000>;
opp-microvolt = <1210000 950000 1250000>;
opp-supported-hw = <0xFF 0x04>;
};
};
But for DRA714 SOC the maximum frequency to be set is 600 MHZ.
Question/Request.
- Please provide us the OPP values for 600Mhz for DRA714 SOC ?
- What is the maximum frequency MPU in DRA714 can be used, Can it run for 1 Ghz only during the boot up time ?
