Subject: [RESEND PATCH v9 0/3] Add support for lan966x flexcom chip-select configuration

This patch series converts atmel-flexcom bindings into json-schema format.
Adds support for lan966x flexcom chip-select configurations and its
DT bindings.

v8 -> v9:
 - generated patches on linux-next v6.0.0-rc4 to resend.
 - Changed reference provided for spi bindings to atmel,at91rm9200-spi.yaml

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).

   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.

Kavyasree Kotagiri (3):
  dt-bindings: mfd: Convert atmel-flexcom to json-schema
  dt-bindings: mfd: atmel,sama5d2-flexcom: Add new compatible string for
    lan966x
  mfd: atmel-flexcom: Add support for lan966x flexcom chip-select
    configuration
