SubjectRe: [PATCH v2 03/10] pwm: imx: Rewrite imx_pwm_*_v1 code to facilitate switch to atomic pwm operation
Hi Sascha,

At least on my setup (i.MX6q) the ipg clock (ipg_clk) don't need to be
explicitly enabled in the ->apply() callback (in the pwm-imx.c) when
MX3_PWMCR_CLKSRC_IPG (0x01 - ipg_clk) is selected as the PWM source.

Best regards,
Łukasz Majewski
