Subject: pwm: imx: set can_sleep flag for imx_pwm
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=31c4fa3442570d001f58303dea36d81693bc199c;p=linux-beck.git

pwm: imx: set can_sleep flag for imx_pwm

The .config() hook imx_pwm_config() calls clk APIs like clk_prepare()
and clk_get_rate(), which might sleep, so we need to set can_sleep flag
on pwm_chip.
