[PATCH net-next v12 0/7] MediaTek Ethernet Patches on MT8195

From: Biao Huang
Date: Mon Jan 17 2022 - 02:07:33 EST


Changes in v12:
1. add a new patch "stmmac: dwmac-mediatek: re-arrange clock setting" to
this series, to simplify clock handling in driver, which benefits to
binding file mediatek-dwmac.yaml.
2. modify dt-binding description in patch "net: dt-bindings: dwmac: add
support for mt8195" as Rob's comments in v10 series, put mac_cg to the
end of clock list.
3. there are small changes in patch "stmmac: dwmac-mediatek: add support
for mt8195", @AngeloGioacchino, please review it kindly.

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@xxxxxxxxxxxx/):
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

Changes in v1:
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
