From d41e127757f37d0d47ccda4af2fe74c32533f798 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 18 Jan 2023 11:01:36 +0100 Subject: net: mdio: Rework scanning of bus ready for quirks Some C22 PHYs do bad things when there are C45 transactions on the bus. In order to handle this, the bus needs to be scanned first for C22 at all addresses, and then C45 scanned for all addresses. The Marvell pxa168 driver scans a specific address on the bus to find its PHY. This is a C22 only device, so update it to use the c22 helper.
