Subject: [PATCH v3 2/4] dt-bindings: net: Add Loongson-1 Ethernet Controller
Date: Thu, 24 Aug 2023 20:50:10 +0800 [thread overview]
Message-ID: <20230824125012.1040288-3-keguang.zhang@gmail.com> (raw)
In-Reply-To: <20230824125012.1040288-1-keguang.zhang@gmail.com>
Add devicetree binding document for Loongson-1 Ethernet controller.
Signed-off-by: Keguang Zhang <keguang.zhang@gmail.com>
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
---
V2 -> V3: Split the DT-schema file into loongson,ls1b-gmac.yaml
and loongson,ls1c-emac.yaml (suggested by Serge Semin)
Change the compatibles to loongson,ls1b-gmac and loongson,ls1c-emac
Rename loongson,dwmac-syscon to loongson,ls1-syscon
Amend the title
Add description
Add Reviewed-by tag from Krzysztof Kozlowski(Sorry! I'm not sure)
V1 -> V2: Fix "clock-names" and "interrupt-names" property
Rename the syscon property to "loongson,dwmac-syscon"
Drop "phy-handle" and "phy-mode" requirement
Revert adding loongson,ls1b-dwmac/loongson,ls1c-dwmac
to snps,dwmac.yaml
