Subject: Revert "pmic: pca9450: Add optional SD_VSEL GPIO for LDO5"
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b7360bd9e8e05dcfd1b4e5fd1c996aabf919e180;p=thirdparty%2Fu-boot.git

Revert "pmic: pca9450: Add optional SD_VSEL GPIO for LDO5"

This reverts commit 2add0511757e2c5897a88b57c5ea8c912140e60f.

It turns out that all boards using the PCA9450 actually have the
SD_VSEL input connected to the VSELECT signal of the SoCs SD/MMC
interface. Therefore we don't need manual control for this signal
via GPIO and there aren't any users.

This is equivalent to the following change in Linux:
