Signed-off-by: Kavyasree Kotagiri Reviewed-by: Rob Herring --- v7 -> v8: - Added back patternProperties for child nodes. 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 that is accepted, I will add back spi example through new patch. v4 -> v5: - Fixed indentations. v3 -> v4: - Corrected format of enum used for compatible string. v2 -> v3: - used enum for compatible string. - changed irq flag to IRQ_TYPE_LEVEL_HIGH in example. - fixed dtschema errors. v1 -> v2: - Fix title. .../bindings/mfd/atmel,sama5d2-flexcom.yaml | 92 +++++++++++++++++++ .../devicetree/bindings/mfd/atmel-flexcom.txt | 63 ------------- 2 files changed, 92 insertions(+), 63 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/atmel,sama5d2-flexcom.yaml delete mode 100644 Documentation/devicetree/bindings/mfd/atmel-flexcom.txt diff --git a/Documentation/devicetree/bindings/mfd/atmel,sama5d2-flexcom.yaml b/Documentation/devicetree/bindings/mfd/atmel,sama5d2-flexcom.yaml new file mode 100644 index 000000000000..bfa7d340a198 --- /dev/null +++ b/Documentation/devicetree/bindings/mfd/atmel,sama5d2-flexcom.yaml @@ -0,0 +1,92 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mfd/atmel,sama5d2-flexcom.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Atmel Flexcom (Flexible Serial Communication Unit) + +maintainers: + - Kavyasree Kotagiri + +description: + The Atmel Flexcom is just a wrapper which embeds a SPI controller, + an I2C controller and an USART.
