From 164147f094ec5d0fc2c2098a888f4b50cf3096a7 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Mon, 7 Jun 2021 08:54:33 +0200 Subject: [PATCH] arm64: dts: meson-sm1-odroid-hc4: add regulators controlled by GPIOH_8 As described in the HC4 schematics, GPIOH_8 controls the USB 5V and 12V regulators used to power the SATA drives. And is set as Open Drain since this GPIO doesn't support Push-Pull.
