A RK8XX PMIC is typically using i2c0 on RK356x devices. Add bootph-all
to required pinctrl nodes to simplify use of the prevent booting on
power plug-in option in SPL.
With the following Kconfig options and nodes in u-boot.dtsi the prevent
booting on power plug-in option can work in SPL.
CONFIG_ROCKCHIP_RK8XX_DISABLE_BOOT_ON_POWERON=y
CONFIG_SPL_I2C=y
CONFIG_SPL_POWER=y
CONFIG_SPL_PINCTRL=y
CONFIG_SPL_PMIC_RK8XX=y
&i2c0 {
bootph-pre-ram;
};
&rk817 {
bootph-pre-ram;
regulators {
bootph-pre-ram;
};
};
