Some of the pin-controllers like the Qualcomms "qcom,pm8921", which require a pinconf to be setup to use pins as gpios. Using the pins directly without pinconf setup would result in incorrect output voltage or load settings. On the other hand pwrseq code does not configure the pinctrl by default as it does not go thru the driver core. This patch adds a call to pinctrl_bind_pins() to bind pins which are going to be used as gpios. Signed-off-by: Srinivas Kandagatla <redacted>
Thanks, applied for next! I add the "mmc:" to the prefix of the commit message header. Kind regards Uffe
