From 3940a471553a31cda4e19024a1bf5bbdc4ac9e46 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 6 Jul 2020 01:40:46 +0100 Subject: [PATCH] sunxi: Pine-H64: Explicitly enable PHY regulator According to the devicetree and the schematic, the 3.3V power rail for the PHY is enabled by GPIO PC16. It's wired as active-high, with a pull-up resistor, so actually works already when the GPIO is in High-Z state. However we should not take any chances and explicitly set the GPIO pin to high, to avoid accidentally losing the PHY power. The existing MACPWR Kconfig allows to do this easily.
