[PATCH v5 1/2] dt-bindings: net: Add ICSSG Ethernet
Posted by MD Danish Anwar 2 years, 7 months ago
From: Puranjay Mohan <p-mohan@ti.com>

Add a YAML binding document for the ICSSG Programmable real time unit
based Ethernet hardware. The ICSSG driver uses the PRU and PRUSS consumer
APIs to interface the PRUs and load/run the firmware for supporting
ethernet functionality.

Odd line wrap length. It should be 80 chars.

I believe we have a standard 'sram' property to point to SRAM nodes 
assuming this is just mmio-sram or similar.

Yes, we have standard 'sram' property but Krzysztof had asked me to make the
sram property vendor specific in last revision of this series.

Sorry about that. I missed that we already have a 'sram'. The question
remains whether this is a phandle to MMIO SRAM or similar (sram.yaml).

The SRAM that we are using here is phandle to MMIO-SRAM only. In the example
section you can see, sram node points to msmc_ram (ti,sram = <&msmc_ram>;) And
msmc_ram has compatible as "mmio-sram" in k3-am65-main.dtsi [1].

	msmc_ram: sram@70000000 {
		compatible = "mmio-sram";
		reg = <0x0 0x70000000 0x0 0x200000>;

So I can use 'sram' property as there is no need to make this as ti specific.
Let me know if it seems good to you.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hi Rob,
This patch depends on the patch [1] which is posted through series [2]. Patch
[1] is currently approved, reviewed and will soon be merged to mainline Linux.
Once it is merged this patch won't throw the above error.

In the meantime I have posted this patch to get it reviewed so that once patch
[1] gets merged, this will be ready to be merged.
