Add needed information inside CPU0 for the generic cpufreq-cpu0 driver. - clock-latency = 300 us Approximate worst-case latency to do clock transition for every OPPs. Using an arbitrary safe value similar to r8a7791(R-Car M2) Soc. - operating-points = < kHz - uV > List of 6 operating points. All of them are using the same voltage since DVS is not supported in RZ/G1 Soc. Note:This also fixes the below errors seen on kernel logs [ 0.876877] cpu cpu0: dev_pm_opp_get_opp_count: OPP table not found (-19) [ 0.883727] cpu cpu1: cpufreq_init: failed to get clk: -2 Signed-off-by: Biju Das <biju.das@bp.renesas.com> --- arch/arm/boot/dts/r8a7743.dtsi | 9 +++++++++ 1 file changed, 9 insertions(+)
