  This series brings a variety of fixes and enhancements for mtk_eth_soc,
adds support for the MT7981 SoC and facilitates sharing the SGMII PCS
code between mtk_eth_soc and mt7530.

Note that this series depends on commit 697c3892d825
("regmap: apply reg_base and reg_downshift for single register ops") to
not break mt7530 pcs register access.

The whole series has been tested on MT7622+MT7531 (BPi-R64),
MT7623+MT7530 (BPi-R2), MT7981+GPY211 (GL.iNet GL-MT3000) and
MT7986+MT7531 (BPi-R3).

Changes since v10:
 * improve mediatek,mt7981-eth dt-bindings
 * use regmap_set_bits instead of regmap_update_bits where possible
 * completely remove mtk_sgmii.c
 * no need to keep struct mtk_sgmii either as it had only a single
   element

Changes since v9:
 * fix path in mediatek,sgmiisys dt-binding

Changes since v8:
 * move mediatek,sgmiisys dt-bindings to correct net/pcs folder
 * rebase on top of net-next/main so series applies cleanly again

Changes since v7:
 * move mediatek,sgmiisys.yaml to more appropriate folder
 * don't include <linux/phylink.h> twice in PCS driver, sort includes

Changes since v6:
 * label MAC MCR bit 12 in 08/12, MediaTek replied explaining its function

Changes since v5:
 * drop dev pointer also from struct mtk_sgmii, pass it as function
   parameter instead
 * address comments left for dt-bindings
 * minor improvements to commit messages

Changes since v4:
 * remove unused dev pointer in struct pcs_mtk_lynxi
 * squash link timer check into correct follow-up patch

Changes since v3:
 * remove unused #define's
 * use BMCR_* instead of #define'ing our own constants
 * return before changing registers in case of invalid link timer

Changes since v2:
 * improve dt-bindings, convert sgmisys bindings to dt-schema yaml
 * fix typo

Changes since v1:
 * apply reverse xmas tree everywhere
 * improve commit descriptions
 * add dt binding documentation
 * various small changes addressing all comments received for v1
