[PATCH v3 0/9] imx8mm: add pwm-imx backlight support

[Tommaso Merciai]

Hi,
This series add support for pwm/backlight on i.MX8MM evk,
separe also CONFIG_DM_PWM pwm-imx implementation from non dm
implementation moving pwm-imx-util into pwm-imx with driver
refactoring.

1. add pwm ctrl registers fields for i.MX8MM SOC
2. add pwm_regs struct for i.MX8MM SOC
3. add pwm clocks support for i.MX8MM SOC
4. move pwm-imx-util into pwm-imx
5. get and enable per/ipg clock using dm
6. introduce pwm_dm_imx_get_parms
7. separe dm from non dm implementation into pwm-imx driver
8. add pwm1/backlight dts support for imx8mm_evk
9. add pwm backlight configs support for imx8mm_evk
