[PATCH net-next v9 00/13] net: phy: mediatek: Introduce mtk-phy-lib and add 2.5Gphy support

[Sky Huang]

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

This patch series integrate MediaTek's built-in Ethernet PHY helper functions

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:

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

Changes in v9:

[PATCH net-next v9 03/13] net: phy: mediatek: Move LED helper functions into mtk phy lib

[Sky Huang]

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

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.

Signed-off-by: SkyLake.Huang <skylake.huang@mediatek.com>
---
Changes in v8:
- Break this patch into smaller slices. Now this patch only shows that we
move LED code from mtk-ge-soc.c to mtk-phy-lib.c & mtk-phy.h. And sure, we
need to slighly modify mtk-ge-soc.c so it can use those helper functions.

Changes in v9:
- Also integrate led number checking and delay time setting in mtk phy
  lib.

[PATCH net-next v9 04/13] net: phy: mediatek: Improve readability of mtk-phy-lib.c's mtk_phy_led_hw_ctrl_set()

[Sky Huang]

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

This patch removes parens around TRIGGER_NETDEV_RX/TRIGGER_NETDEV_TX in
mtk_phy_led_hw_ctrl_set(), which improves readability.

[PATCH net-next v9 06/13] net: phy: mediatek: Hook LED helper functions in mtk-ge.c

[Sky Huang]

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

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.

Signed-off-by: SkyLake.Huang <skylake.huang@mediatek.com>
---
Changes in v9:
- Led number checking & delay settings are integrated into common code, so
  just use it.

[PATCH net-next v9 07/13] net: phy: mediatek: add MT7530 & MT7531's PHY ID macros

[Sky Huang]

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

This patch adds MT7530 & MT7531's PHY ID macros in mtk-ge.c so that
it follows the same rule of mtk-ge-soc.c.

Signed-off-by: SkyLake.Huang <skylake.huang@mediatek.com>
---
Changes in v9:
- Remove ".led_hw_is_supported = mt753x_phy_led_hw_is_supported," in
  MT7530's callback function hooking of mtk-ge.c because it's
  mistakenly added.

[PATCH net-next v9 09/13] net: phy: mediatek: Add token ring access helper functions in mtk-phy-lib

[Sky Huang]

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

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.

[PATCH net-next v9 10/13] net: phy: mediatek: Extend 1G TX/RX link pulse time

[Sky Huang]

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

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

[PATCH net-next v9 11/13] net: phy: add driver for built-in 2.5G ethernet PHY on MT7988

[Sky Huang]

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

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.

[PATCH net-next v9 12/13] net: phy: mediatek: Fix alignment in callback functions' hook

[Sky Huang]

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

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.

Hi Sky,

Sorry for not providing this review earlier in the process.

It seems that this leaks any resources allocated by request_firmware():
I think a call to release_firmware() is needed in this unwind path.

I'm feeling that I'm missing something incredibly obvious,
but could this simply be:

	return ret;

Thanks. I'll fix like this:

static int mt798x_2p5ge_phy_load_fw(struct phy_device *phydev)
{
	int ret, i;
	...

	if (!md32_en_cfg_base) {
		ret = -ENOMEM;
		goto free_pmb;
	}

	ret = request_firmware(&fw, MT7988_2P5GE_PMB_FW, dev);
	if (ret) {
		dev_err(dev, "failed to load firmware: %s, ret: %d\n",
			MT7988_2P5GE_PMB_FW, ret);
		goto free;
	}

	if (fw->size != MT7988_2P5GE_PMB_FW_SIZE) {
		dev_err(dev, "Firmware size 0x%zx != 0x%x\n",
			fw->size, MT7988_2P5GE_PMB_FW_SIZE);
		ret = -EINVAL;
		goto release_fw;
	}

	...
	for (i = 0; i < MT7988_2P5GE_PMB_FW_SIZE - 1; i += 4)
		writel(*((uint32_t *)(fw->data + i)), pmb_addr + i);
	/* Remove original release_firmware(fw) here */
	...

release_fw:
	release_firmware(fw);
free:
	iounmap(md32_en_cfg_base);
free_pmb:
	iounmap(pmb_addr);

	return ret;
}

BRs,
