[PATCH net-next v8 00/13] net: phy: mediatek: Introduce mtk-phy-lib and add 2.5Gphy support

[Sky Huang <SkyLake.Huang@mediatek.com>]

From: "SkyLake.Huang" <skylake.huang@mediatek.com>

This patch series integrate MediaTek's built-in Ethernet PHY helper functions
into mtk-phy-lib and add more functions into it. Also, add support for 2.5Gphy
on MT7988 SoC.

Changes in v2:
- Apply correct PATCH tag.
- Break LED/Token ring/Extend-link-pulse-time features into 3 patches.
- Fix contents according to v1 comments.

Changes in v3:
- Rebase code and now this patch series can apply to net-next tree.
[PATCH 4/5]
Refactor mtk_gphy_cl22_read_status() with genphy_read_status().
[PATCH 5/5]
1. Add range check for firmware.
2. Fix c45_ids.mmds_present in probe function.
3. Still use genphy_update_link() in read_status because
genphy_c45_read_link() can't correct detect link on this phy.

Changes in v4:
[PATCH 4/5]
1. Change extend_an_new_lp_cnt_limit()'s return type and all return values
2. Refactor comments in extend_an_new_lp_cnt_limit()
[PATCH 5/5]
1. Move firmware loading function to mt798x_2p5ge_phy_load_fw()
2. Add AN disable warning in mt798x_2p5ge_phy_config_aneg()
3. Clarify the HDX comments in mt798x_2p5ge_phy_get_features()

Changes in v5:
- Fix syntax errors of comments in drivers/net/phy/mediatek/*
[PATCH 1/5]
- Change MEDIATEK_GE_SOC_PHY from bool back to tristate.
[PATCH 5/5]
1. Move md32_en_cfg_base & pmb_addr to local variables to achieve
symmetric code.
2. Print out firmware date code & version.
3. Don't return error if LED pinctrl switching fails. Also, add
comments to this unusual operations.
4. Return -EOPNOTSUPP for AN off case in config_aneg().

Changes in v6:
- Re-arrange patch and changes description in cover letter.
- Contraint code inside 80 columns wide.
[PATCH 4/5]
1. Add LP_DETECTED so extend_an_new_lp_cnt_limit() won't be called every
time we poll the PHY for its status. It'll be called only when cable is
plugged in and 1G training starts.
2. Call phy_read_paged() instead of calling phy_select_page() &
phy_restore_page() pair.
[PATCH 5/5]
1. Force casting (fw->data + MT7988_2P5GE_PMB_SIZE - 8) with __be16.
2. Remove parens on RHS of "phydev->c45_ids.mmds_present |=".
3. Add PHY_INTERFACE_MODE_INTERNAL check in
mt798x_2p5ge_phy_get_rate_matching()
4. Arrange local variables in reverse Xmas tree order.

Changes in v7:
[PATCH 5/5]
1. Add phy mode check(PHY_INTERFACE_MODE_INTERNAL) in config_init().
2. Always return RATE_MATCH_PAUSE in get_rate_matching().

Changes in v8:
- Make sure that each variables in drivers/net/phy/mediatek/* follows reverse
Xmas tree order.
- Split v7 patches in this way:

- Create another 2 patches to:

  - Remove unnecessary outer parens of "supported_triggers" var
- Replace token ring API, tr* & __tr* with mtk_tr* & __mtk_tr* and fix
alignment.
