From 737eb75a815f9c08dcbb6631db57f4f4b0540a5b Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Tue, 6 Feb 2024 18:31:07 +0100 Subject: [PATCH 04/10] net: phy: qcom: move more function to shared library Move more function to shared library in preparation for introduction of new PHY Family qca807x that will make use of both functions from at803x and qca808x as it's a transition PHY with some implementation of at803x and some from the new qca808x.
