UART pinctrl for serial is typically applied multiple times: - in external TPL - in SPL using pinctrl from DT - in pre-reloc phase using pinctrl from DT - after relocation using pinctrl from DT Skip including UART pinctrl for the pre-reloc phase to save time during boot. On a Radxa ROCK Pi S this reduce boot time by ~80 ms. After this a warning may be shown with LOGLEVEL=5 (or higher), it is safe to ignore this warning as device probe is successful even when pinctrl cannot be applied: ns16550_serial serial@ff0a0000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19 Signed-off-by: Jonas Karlman <jonas@kwiboo.se> --- arch/arm/dts/rk3308-evb-u-boot.dtsi | 3 ++- arch/arm/dts/rk3308-roc-cc-u-boot.dtsi | 3 ++- arch/arm/dts/rk3308-rock-pi-s-u-boot.dtsi | 3 ++- arch/arm/dts/rk3308-rock-s0-u-boot.dtsi | 3 ++- 4 files changed, 8 insertions(+), 4 deletions(-)
