Subject: Re: [PATCH V4 2/2] clk: imx: scu: add cpu frequency scaling support

Quoting Anson Huang (2019-02-13 17:54:08)

quoted

On NXP's i.MX SoCs with system controller inside, CPU frequency
scaling can ONLY be done by system controller firmware, and it can
ONLY be requested from secure mode, so Linux kernel has to call ARM
SMC to trap to ARM-Trusted-Firmware to request system controller
firmware to do CPU frequency scaling.

This patch adds i.MX system controller CPU frequency scaling support,
it reuses cpufreq-dt driver and implement the CPU frequency scaling
inside SCU clock driver.

Unless you wanted me to pick this patch up into clk-next?

Yes, please, we want to support cpu-freq scaling in Linux next tree ASAP.

Thanks,
Anson.
