Subject: [PATCH 175/224] net: mediatek: remove superfluous pin setup for
|
|
MT7622 SoC
|
|
|
|
Remove superfluous pin setup to get out of accessing invalid I/O pin
|
|
registers because the way for pin configuring tends to be different from
|
|
various SoCs and thus it should be better being managed and controlled by
|
|
the pinctrl driver which MT7622 already can support.
