Subject: pinctrl: imx: Convert to use livetree API for fdt access
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=59382d2cb9f5aef06f2de8a24b283466c0c1cf50;p=u-boot.git

pinctrl: imx: Convert to use livetree API for fdt access

Convert to using livetree API functions.

Without this if livetree is enabled (OF_LIVE) the imx8mq-pinctrl
driver will (silently) fail to probe causing issues with multiple
devices.
