From b0884cf28fa32c06d9649ed585d688a9cbdf18e1 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Mon, 8 Mar 2021 16:18:27 +0100 Subject: [PATCH] ARM: dts: imx6q-ba16: improve PHY information Add PHY voltage supply information fixing the following kernel message: 2188000.ethernet supply phy not found, using dummy regulator Also add PHY clock information to avoid depending on the bootloader programming correct values. The bootloader also sets some reserved registers in the PHY as advised by Qualcomm, which is not supported by the bindings/kernel driver, so the reset GPIO has not been added intentionally.
