That is more generic solution than "mediatek,mtd-eeprom" which is MTD specific. Add support for EEPROM NVMEM cells and deprecate existing MTD-based property. Cc: Christian Marangi Signed-off-by: Rafał Miłecki Acked-by: Krzysztof Kozlowski --- Ansuel is working on mt76 driver support for NVMEM based EEPROM access: https://github.com/openwrt/mt76/pull/765 I took the liberty to propose this binding patch. One important difference: my binding uses "eeprom" while Ansuel went with "precal". I found a lot of "eeprom" references and only one "precal". If you think however "precal" fits better please comment. --- .../bindings/net/wireless/mediatek,mt76.yaml | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml b/Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml index 67b63f119f64..0500caa4107c 100644 --- a/Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml +++ b/Documentation/devicetree/bindings/net/wireless/mediatek,mt76.yaml @@ -71,6 +71,14 @@ properties: ieee80211-freq-limit: true + nvmem-cells: + items: + - description: NVMEM cell with EEPROM + + nvmem-cell-names: + items: + - const: eeprom + mediatek,eeprom-data: $ref: /schemas/types.yaml#/definitions/uint32-array description: @@ -84,6 +92,7 @@ properties: - description: offset containing EEPROM data description: Phandle to a MTD partition + offset containing EEPROM data + deprecated: true big-endian: $ref: /schemas/types.yaml#/definitions/flag @@ -258,7 +267,8 @@ examples: interrupt-parent = <&cpuintc>; interrupts = <6>; - mediatek,mtd-eeprom = <&factory 0x0>; + nvmem-cells = <&eeprom>; + nvmem-cell-names = "eeprom"; }; - |
