Series [1/2] pinctrl: pinctrl-imx: Add suspend/resume for LPSR | expand

Commit Message

Abel Vesa March 25, 2019, 1:48 p.m. UTC 
Add suspend/resume pm ops to the pinctrl i.MX8MQ driver.
Make the suspend late and the resume early since some of the
pins might be needed active very late.
These call the pinctrl-imx generic handlers.
