X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=bd9fbe2781993259ea9241be7452e1355ceffb87;p=thirdparty%2Flinux.git

arm64: dts: ti: k3-j721s2-som-p0: add bootph-pre-ram property to PMIC-B

On j721s2, PMIC-B is needed to exit the DDR from retention after
suspend-to-ram. Add bootph-pre-ram property to make PMIC-B available to
the bootloader in the phase that sets up the DDR.
