I will fix it in v2. Thanks.

Maybe, but breaks the ABI. It also looks like a step backwards.

Can you please give some more details about ABI breakage? mtk_wed driver is supposed to be backward compatible with respect to the older dts description (please take a look to patch 5/10 and 8/10). > > > > > Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> > > --- > > .../arm/mediatek/mediatek,mt7622-wed.yaml | 14 +++--- > > .../soc/mediatek/mediatek,mt7986-wo-ilm.yaml | 45 +++++++++++++++++++ > > 2 files changed, 53 insertions(+), 6 deletions(-) > > create mode 100644 Documentation/devicetree/bindings/soc/mediatek/mediatek,mt7986-wo-ilm.yaml > > > > diff --git a/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7622-wed.yaml b/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7622-wed.yaml > > index 7f6638d43854..5d2397ec5891 100644 > > --- a/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7622-wed.yaml > > +++ b/Documentation/devicetree/bindings/arm/mediatek/mediatek,mt7622-wed.yaml > > @@ -32,14 +32,12 @@ properties: > > memory-region: > > items: > > - description: firmware EMI region > > - - description: firmware ILM region > > - description: firmware DLM region > > - description: firmware CPU DATA region > > > > memory-region-names: > > items: > > - const: wo-emi > > - - const: wo-ilm > > - const: wo-dlm > > - const: wo-data > > > > @@ -51,6 +49,10 @@ properties: > > $ref: /schemas/types.yaml#/definitions/phandle > > description: mediatek wed-wo cpuboot controller interface. > > > > + mediatek,wo-ilm: > > + $ref: /schemas/types.yaml#/definitions/phandle > > + description: mediatek wed-wo ilm interface. > > + > > allOf: > > - if: > > properties: > > @@ -63,6 +65,7 @@ allOf: > > memory-region: false > > mediatek,wo-ccif: false > > mediatek,wo-cpuboot: false > > + mediatek,wo-ilm: false > > > > required: > > - compatible > > @@ -97,11 +100,10 @@ examples: > > reg = <0 0x15010000 0 0x1000>; > > interrupts = <GIC_SPI 205 IRQ_TYPE_LEVEL_HIGH>; > > > > - memory-region = <&wo_emi>, <&wo_ilm>, <&wo_dlm>, > > - <&wo_data>; > > - memory-region-names = "wo-emi", "wo-ilm", "wo-dlm", > > - "wo-data"; > > + memory-region = <&wo_emi>, <&wo_dlm>, &wo_data>; > > + memory-region-names = "wo-emi", "wo-dlm", "wo-data"; > > mediatek,wo-ccif = <&wo_ccif0>; > > mediatek,wo-cpuboot = <&wo_cpuboot>; > > + mediatek,wo-ilm = <&wo_ilm>; > > }; > > }; > > diff --git a/Documentation/devicetree/bindings/soc/mediatek/mediatek,mt7986-wo-ilm.yaml b/Documentation/devicetree/bindings/soc/mediatek/mediatek,mt7986-wo-ilm.yaml > > new file mode 100644 > > index 000000000000..2a3775cd941e > > --- /dev/null > > +++ b/Documentation/devicetree/bindings/soc/mediatek/mediatek,mt7986-wo-ilm.yaml > > @@ -0,0 +1,45 @@ > > +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) > > +%YAML 1.2 > > +--- > > +$id: http://devicetree.org/schemas/soc/mediatek/mediatek,mt7986-wo-ilm.yaml# > > +$schema: http://devicetree.org/meta-schemas/core.yaml# > > + > > +title: MediaTek Wireless Ethernet Dispatch (WED) WO ILM firmware interface for MT7986 > > Either this region is some memory or it's a device. Sounds like the > former and this is not a 'syscon'. ILM and DLM are mmio regions used to store Wireless Ethernet Dispatch firmware sections. AFAIU reserved-memory nodes are supposed to be used just for RAM areas, correct? What do you think would be the best dts node type for ILM and DLM? Another possibility I was discussing with Felix is to move ILM and DLM definitions in WED node reg section, something like: wed0: wed@15010000 { compatible = "mediatek,mt7986-wed"; reg = <0 0x15010000 0 0x1000>, <0 0x151e0000 0 0x8000>, <0 0x151e8000 0 0x2000>; ... }; Doing so we need to get rid of syscon in WED compatible string, right? Is it acceptable?

Since the cpuboot memory region is not part of the RAM SoC, move ilm in a deidicated syscon node. This patch helps to keep backward-compatibility with older version of uboot codebase where we have a limit of 8 reserved-memory dts child nodes.
