From eec493cd33e8c7a90ed0d9e3964111c7d88e9ea9 Mon Sep 17 00:00:00 2001 From: Yemike Abhilash Chandra Date: Tue, 15 Apr 2025 16:43:22 +0530 Subject: [PATCH] arm64: dts: ti: k3-j721e-sk: Add DT nodes for power regulators commit 97b67cc102dc2cc8aa39a569c22a196e21af5a21 upstream. Add device tree nodes for two power regulators on the J721E SK board. vsys_5v0: A fixed regulator representing the 5V supply output from the LM61460 and vdd_sd_dv: A GPIO-controlled TLV71033 regulator.
