Subject: Re: [PATCH v3 0/7] Add rk3328 pwm support

Hi Thierry,

For the PWM patches, whether we let the first patch land in, that is PWM 
APB and function clocks are different in rk3328 and rv1108 SOCs. If the 
first patch was merged before 4.14, it will guarantee that the PWM is 
working, and the lock function you might review it later.
