Subject: [PATCH net-next v3 0/2] Add built-in 2.5G ethernet phy support on MT7988

From: Sky Huang <skylake.huang@...iatek.com>

This patchset adds support for built-in 2.5Gphy on MT7988, change file
and config sequence in related Kconfig and Makefile.

---
Change in v2:
- Add missing dt-bindings and dts node.
- Remove mtk_phy_leds_state_init() temporarily. I'm going to add LED support
later.
- Remove "Firmware loading/trigger ok" log.
- Add macro define for 0x800e & 0x800f

Change in v3:
1. Remove unnecessary headers and unnecessary print log.
2. ioremap IO space (MT7988_2P5GE_PMB_FW_BASE/MTK_2P5GPHY_MCU_CSR_BASE)
directly instead of of_iomap() compatible node (mediatek,2p5gphy-fw) from dtsi
3. Call mt798x_2p5ge_phy_load_fw() from .probe instead of .config_init. This is
tested ok with openWRT-24.10 and "mediatek/mt7988/i2p5ge-phy-pmb.bin" firmware
is embedded into kernel image instead of rootfs image.
4. Use request_firmware_direct instead of request_firmware. We don't want sysfs
fallback in this driver to avoid blocking.
5. Remove mtk_i2p5ge_phy_priv sturct since it's not used anymore.
