From fada2ce09308bc79e27876b8a89c7de38265f730 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Wed, 6 Oct 2021 00:54:01 +0200 Subject: [PATCH] net: phy: at803x: add QCA9561 support Add support for the embedded fast-ethernet PHY found on the QCA9561 WiSoC platform. It supports the usual Atheros PHY featureset including the cable tester.
