Adds support for lan966x flexcom chip-select configurations and its DT bindings. v8 -> v9: - Use full schema path for i2c bindings. v7 -> v8: - Added back patternProperties for child nodes. - Changed compatible string to microchip,lan9668-flexcom. v6 -> v7: - Change filename to atmel,sama5d2-flexcom.yaml - Add #address-cells, #size-cells to flexcom node - Fixed warnings. v5 -> v6: - Removed spi node from example as suggested by Rob and also pattern properties(spi dt-bindings conversion to yaml patch is under review). https://patchwork.kernel.org/project/linux-arm-kernel/patch/20220629125804.137099-1-sergiu.moga@microchip.com/ Once this is accepted, I will add back spi example through new patch. v4 -> v5: - Fix indentations of DT example. - Fix dt-schema errors - removed minItems, maxItems for allOf:if:then "reg" property as it is not required. v3 -> v4: - Fix dtschema errors. - Add a condition to flexcom chip-selects configuration as chip-select lines are optional. v2 -> v3: - changed IRQ flag in dt-bindings example. - added reg property specific to lan66x which is missed in v2. - used goto label for clk_disable in error cases. v1 -> v2: - minor fix in title of dt-bindings. - Modified new dt properties usage in atmel,flexcom.yaml. - Used GENMASK and macros for maximum allowed values. - Use u32 values for flexcom chipselects instead of strings. - disable clock in case of errors.
