Subject: Re: [PATCH] clk: Add PWM clock driver

Hi,

http://patchwork.ozlabs.org/patch/359069/
https://lkml.org/lkml/2014/6/12/186

Will the patch ever included to linux-next?

pwm_config()  API could be extended to support
not only period [ns] and duty [ns] time
but also frequency [Hz] and duty cycle fraction [1/1000?]
(instead of time in ns) as parameters.
Then  ns (rounded by pwm) to freq. conversion problem
inclk_pwm_recalc_rate() usingpwm_get_period()
could be avoided.
To extend the API pwm_config() can support
new flags forduty_ns and period_ns,
eg. PWM_DUTY_PERCENT and PWM_PERIOD_HZ.

best regards
Janusz
