Subject: [PATCH 03/13] net: phy: mediatek: Move LED helper functions into mtk
phy lib
This patch creates mtk-phy-lib.c & mtk-phy.h and integrates mtk-ge-soc.c's
LED helper functions so that we can use those helper functions in other
MTK's ethernet phy driver.

Subject: [PATCH 04/13] net: phy: mediatek: Improve readability of
mtk-phy-lib.c's mtk_phy_led_hw_ctrl_set()
This patch removes parens around TRIGGER_NETDEV_RX/TRIGGER_NETDEV_TX in
mtk_phy_led_hw_ctrl_set(), which improves readability.

functions
This patch integrates read/write page helper functions as MTK phy lib.
They are basically the same in mtk-ge.c & mtk-ge-soc.c.

Subject: [PATCH 06/13] net: phy: mediatek: Hook LED helper functions in
mtk-ge.c
We have mtk-phy-lib.c now so that we can use LED helper functions in
mtk-ge.c(mt7531 part). It also means that mt7531/mt7981/mt7988's
Giga ethernet phys share almost the same HW LED controller design.
Also, add probe function for mt7531 so that it can initialize LED state.

From 60228de48d8bfde62b4db5945314e6a62079f091 Mon Sep 17 00:00:00 2001
From: "SkyLake.Huang" <skylake.huang@mediatek.com>
Date: Mon, 1 Jul 2024 18:54:13 +0800
Subject: [PATCH 09/13] net: phy: mediatek: Add token ring access helper
functions in mtk-phy-lib
This patch adds TR(token ring) manipulations and adds correct
macro names for those magic numbers. TR is a way to access
proprietary registers on page 52b5. Use these helper functions
so we can see which fields we're going to modify/set/clear.
This patch doesn't really change registers' settings but just
enhances readability and maintainability.

From 3c05195fc2c232cd853fc8cebf55310c4605111d Mon Sep 17 00:00:00 2001
From: "SkyLake.Huang" <skylake.huang@mediatek.com>
Date: Mon, 1 Jul 2024 18:54:14 +0800
Subject: [PATCH 10/13] net: phy: mediatek: Extend 1G TX/RX link pulse time
We observe that some 10G devices' (mostly Marvell's chips inside) 1G
training time violates specification, which may last 2230ms and affect
later TX/RX link pulse time. This will invalidate MediaTek series
gigabit Ethernet PHYs' hardware auto downshift mechanism.
Without this patch, if someone is trying to use "4-wire" cable to
connect above devices, MediaTek' gigabit Ethernet PHYs may fail
to downshift to 100Mbps. (If partner 10G devices' downshift mechanism
stops at 1G)
This patch extends our 1G TX/RX link pulse time so that we can still
link up with those 10G devices.
Tested device:
- Netgear GS110EMX's 10G port (Marvell 88X3340P)
- QNAP QSW-M408-4C

Subject: [PATCH 11/13] net: phy: add driver for built-in 2.5G ethernet PHY on
MT7988
Add support for internal 2.5Gphy on MT7988. This driver will load
necessary firmware, add appropriate time delay and figure out LED.
Also, certain control registers will be set to fix link-up issues.

Align declarations in mtk_gephy_driver(mtk-ge.c) and
mtk_socphy_driver(mtk-ge-soc.c). At first, some of them are
".foo<tab>= method_foo", and others are ".bar<space>= method_bar".
Use space instead for all of them here in case line is longer than
80 chars.
