Subject: [PATCH net-next v14 0/9] net: ethernet: mtk_eth_soc: various
enhancements
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.
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). On the BananaPi R3 a variete of SFP modules
have been tested, all of them (some SGMII with PHY, others 2500Base-X
or 1000Base-X without PHY) are working well now, however, some of them
need manually disabling of autonegotiation for the link to come up.
Changes since v13:
* no longer pile Lorenzo's patches on top, they will be submitted
separately
* patches fixing existing code have been submitted already via 'net'
tree, so they are no longer included in this series.
Changes since v12:
* remove patches "fixing" ????Base-X modes. Turns out the cause are
buggy SFP modules for which we will need to introduce quirks rather
than trying to address this in the Ethernet driver.
Changes since v11:
* remove patch "net: ethernet: mtk_eth_soc: fix RX data corruption issue"
as it has already been merged via net tree
* add commits fixing 1000Base-X and 2500Base-X modes after phylink_pcs
conversion
* completely remove mtk_sgmii.c as only about 20 lines were left in that
file
* Add commits from Lorenzo for MT7988 as requested by him
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
