From 813abcd98fb1b2cccf850cdfa092a4bfc50b2363 Mon Sep 17 00:00:00 2001

Date: Tue, 22 Nov 2022 16:42:32 +0800
Subject: [PATCH] net: phy: add Motorcomm YT8531S phy id.
We added patch for motorcomm.c to support YT8531S. This patch has
been tested on AM335x platform which has one YT8531S interface
card and passed all test cases.
The tested cases indluding: YT8531S UTP function with support of
10M/100M/1000M; YT8531S Fiber function with support of 100M/1000M;
and YT8531S Combo function that supports auto detection of media type.
Since most functions of YT8531S are similar to YT8521 and we reuse some
codes for YT8521 in the patch file.

Subject: [PATCH] net: phy: Add dts support for Motorcomm yt8521 gigabit
ethernet phy
Add dts support for Motorcomm yt8521 gigabit ethernet phy.
Add ytphy_rgmii_clk_delay_config function to support dst config for
the delay of rgmii clk. This funciont is common for yt8521, yt8531s
and yt8531.
This patch has been verified on AM335x platform.

Add dts support for Motorcomm yt8531s gigabit ethernet phy.
Change yt8521_probe to support clk config of yt8531s. Becase
yt8521_probe does the things which yt8531s is needed, so
removed yt8531s function.
This patch has been verified on AM335x platform with yt8531s board.

phy
Add a driver for the motorcomm yt8531 gigabit ethernet phy. We have
verified the driver on AM335x platform with yt8531 board. On the
board, yt8531 gigabit ethernet phy works in utp mode, RGMII
interface, supports 1000M/100M/10M speeds, and wol(magic package).

Subject: [PATCH] net: phy: motorcomm: uninitialized variables in
yt8531_link_change_notify()
These booleans are never set to false, but are just used without being
initialized.
