Subject: [PATCH] arm: dts: mt7622: remove default pinctrl of uart0
|
|
|
|
Currently u-boot running on mt7622 will print an warning log at beginning:
|
|
> serial_mtk serial@11002000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
|
|
|
|
It turns out that the pinctrl uclass can't work properly in board_f stage.
|
|
|
|
Since the uart0 is the default UART device used by bootrom, and will be
|
|
initialized in both bootrom and tf-a bl2. It's ok not to setup pinctrl for
|
|
uart0 in u-boot.
|
|
|
|
This patch removes the default pinctrl of uart0 to suppress the unwanted
|
|
warning.
