Subject: power: pmic: Add NXP PCA9451A PMIC support
X-Git-Tag: baikal/mips/sdk6.2~4^2~3^2~175^2~16^2~53
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=4ad7272b72a4df8fa28c29bef99245554c3837f0;p=uboot.git

power: pmic: Add NXP PCA9451A PMIC support

PCA9451A uses similar BUCKs and LDO regulators as PCA9450B/C but
has LDO2 and LDO3 removed. So reuse pca9450 PMIC and regulator driver
and add new type for PCA9451A.
