Subject: board: samsung: e850-96: Configure PMIC regulators
X-Git-Tag: v2025.10-rc4~5^2~9
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8fefc2eb9610b75270f0376980dae952d16fc84b;p=pandora-u-boot.git

board: samsung: e850-96: Configure PMIC regulators

Make use of PMIC configuration routines and enable all LDOs that might
be useful for bootloader and kernel. The most crucial regulator being
enabled at the moment is LDO24 which provides power to LAN9514 chip.
That makes Ethernet controller and USB hub functional.
