We can use those helper functions in mtk-ge.c as well. That is to say, we have almost the same HW LED controller design in mt7530/mt7531/mt7981/mt7988's Giga ethernet phy. Also integrate read/write pages into one helper function. They are basically the same.

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 v3: Refactor mtk_gphy_cl22_read_status() with genphy_read_status(). v4: 1. Change extend_an_new_lp_cnt_limit()'s return type and all return values 2.

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. v2: 1. Move md32_en_cfg_base & pmb_addr detection in probe function. 2. Do not read PMB & MD32_EN_CFG base addresses from dts. We won't change that from board to board. Leave them in driver code. Also, release those addresses after firmware is triggered. 3. Remove half duplex code which leads to ambiguity. Those are for testing & developing previously. 4. Use correct BMCR definitions. 5. Correct config_aneg / get_features / read_status functions. 6. Change mt7988_2p5ge prefix to mt798x_2p5ge in case that our next platform uses this 2.5Gphy driver. v3: 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. v4: 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() v5: 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().
