Add StarFive JH8100 dwmac support.
The JH8100 dwmac shares the same driver code as the JH7110 dwmac
and has only one reset signal.
Please refer to below:
JH8100: reset-names = "stmmaceth";
JH7110: reset-names = "stmmaceth", "ahb";
JH7100: reset-names = "ahb";
Example usage of JH8100 in the device tree:
gmac0: ethernet@16030000 {
compatible = "starfive,jh8100-dwmac",
"starfive,jh7110-dwmac",
"snps,dwmac-5.20";
...
};
[1] https://lore.kernel.org/lkml/20231222101001.2541758-2-cristian.ciocaltea@collabora.com
Changes in v3:
- Postpone until the patch [1] is merged.
- Reorganize the content to accommodate all compatibility specifications.

I guess if the Linux driver treated it that way, we can get away with it. It would simplify the conditionals in the schema if the schema also treated the 2nd entry as optional on JH7110 as well. > JH7100: reset-names = "ahb"; > > Example usage of JH8100 in the device tree: > > gmac0: ethernet@16030000 { > compatible = "starfive,jh8100-dwmac", > "starfive,jh7110-dwmac", > "snps,dwmac-5.20"; > ... > }; > > Signed-off-by: Tan Chun Hau <chunhau.tan@starfivetech.com> > --- > .../devicetree/bindings/net/snps,dwmac.yaml | 1 + > .../bindings/net/starfive,jh7110-dwmac.yaml | 82 +++++++++++++------ > 2 files changed, 58 insertions(+), 25 deletions(-) > > diff --git a/Documentation/devicetree/bindings/net/snps,dwmac.yaml b/Documentation/devicetree/bindings/net/snps,dwmac.yaml > index 6b0341a8e0ea..a6d596b7dcf4 100644 > --- a/Documentation/devicetree/bindings/net/snps,dwmac.yaml > +++ b/Documentation/devicetree/bindings/net/snps,dwmac.yaml > @@ -97,6 +97,7 @@ properties: > - snps,dwxgmac-2.10 > - starfive,jh7100-dwmac > - starfive,jh7110-dwmac > + - starfive,jh8100-dwmac > > reg: > minItems: 1 > diff --git a/Documentation/devicetree/bindings/net/starfive,jh7110-dwmac.yaml b/Documentation/devicetree/bindings/net/starfive,jh7110-dwmac.yaml > index 0d1962980f57..da3cc984fec9 100644 > --- a/Documentation/devicetree/bindings/net/starfive,jh7110-dwmac.yaml > +++ b/Documentation/devicetree/bindings/net/starfive,jh7110-dwmac.yaml > @@ -18,6 +18,7 @@ select: > enum: > - starfive,jh7100-dwmac > - starfive,jh7110-dwmac > + - starfive,jh8100-dwmac > required: > - compatible > > @@ -30,6 +31,10 @@ properties: > - items: > - const: starfive,jh7110-dwmac > - const: snps,dwmac-5.20 > + - items: > + - const: starfive,jh8100-dwmac > + - const: starfive,jh7110-dwmac > + - const: snps,dwmac-5.20 > > reg: > maxItems: 1 > @@ -83,29 +88,13 @@ allOf: > - if: > properties: > compatible: > - contains: > - const: starfive,jh7100-dwmac > - then: > - properties: > - interrupts: > - minItems: 2 > - maxItems: 2 > - > - interrupt-names: > - minItems: 2 > - maxItems: 2 > - > - resets: > - maxItems: 1 > - > - reset-names: > - const: ahb > - > - - if: > - properties: > - compatible: > - contains: > - const: starfive,jh7110-dwmac > + allOf: > + - contains: > + enum: > + - starfive,jh8100-dwmac > + - contains: > + enum: > + - starfive,jh7110-dwmac There's no need for the 2nd entry.
