Subject: [PATCH net-next v11 0/6] MediaTek Ethernet Patches on MT8195

Changes in v11:
1. add reivewed-by in "net: dt-bindings: dwmac: Convert mediatek-dwmac to
   DT schema" as Rob's comments.
2. fall back "net: dt-bindings: dwmac: add support for mt8195" to v8 version
   as mentioned in previous reply(https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20211216055328.15953-7-biao.huang@mediatek.com/):
   2.1 there is already a special clock named "rmii_internal", which need to
       be put to the end of the clock list(driver special handling),
       so we can't simply put new "mac_cg" for mt8195 to the end of the clock
       list.
   2.2 we prefer the if-then schema, which will make mt8195 clock list clearer
       with some duplicated information.
   2.3 we expect the future IC will follow mt2712 or mt8195, so we only need
       add new IC name to compatible list for future IC, and will not make the
       clock list binding files worse.

Changes in v10:
1. add detailed description in "arm64: dts: mt2712: update ethernet
   device node" to make the modifications clearer as Matthias's comments.
2. modify dt-binding description as Rob's comments, and "make dtbs_check" runs
   pass locally with "arm64: dts: mt2712: update ethernet device node"
   in this series.

Changes in v9:
1. remove oneOf for 1 entry as Rob's comments.
2. add new clocks to the end of existing clocks to simplify
   the binding as Rob's comments.

Changes in v8:
1. add acked-by in "stmmac: dwmac-mediatek: add platform level clocks
   management" patch

Changes in v7:
1. fix uninitialized warning as Jakub's comments.

Changes in v6:
1. update commit message as Jakub's comments.
2. split mt8195 eth dts patch("arm64: dts: mt8195: add ethernet device
   node") from this series, since mt8195 dtsi/dts basic patches is still
   under reviewing.
   https://patchwork.kernel.org/project/linux-mediatek/list/?series=579071
   we'll resend mt8195 eth dts patch once all the dependent patches are
   accepted.

Changes in v5:
1. remove useless inclusion in dwmac-mediatek.c as Angelo's comments.
2. add acked-by in "net-next: stmmac: dwmac-mediatek: add support for
   mt8195" patch

Changes in v4:
1. add changes in commit message in "net-next: dt-bindings: dwmac:
   Convert mediatek-dwmac to DT schema" patch.
2. remove ethernet-controller.yaml since snps,dwmac.yaml already include it.

Changes in v3:
1. Add prefix "net-next" to support new IC as Denis's suggestion.
2. Split dt-bindings to two patches, one for conversion, and the other for
   new IC.
3. add a new patch to update device node in mt2712-evb.dts to accommodate to
   changes in driver.
4. remove unnecessary wrapper as Angelo's suggestion.
5. Add acked-by in "net-next: stmmac: dwmac-mediatek: Reuse more common
   features" patch.

Changes in v2:
1. fix errors/warnings in mediatek-dwmac.yaml with upgraded dtschema tools

This series include 5 patches:
1. add platform level clocks management for dwmac-mediatek
2. resue more common features defined in stmmac_platform.c
3. add ethernet entry for mt8195
