If the consensus is to drop this I can send a v3 with an updated driver to add the chip specific complatibles. .../bindings/spi/realtek,rtl9301-snand.yaml | 59 +++++++++++++++++++ 1 file changed, 59 insertions(+) create mode 100644 Documentation/devicetree/bindings/spi/realtek,rtl9301-snand.yaml diff --git a/Documentation/devicetree/bindings/spi/realtek,rtl9301-snand.yaml b/Documentation/devicetree/bindings/spi/realtek,rtl9301-snand.yaml new file mode 100644 index 000000000000..397b32b41e86 --- /dev/null +++ b/Documentation/devicetree/bindings/spi/realtek,rtl9301-snand.yaml @@ -0,0 +1,59 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/spi/realtek,rtl9301-snand.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: SPI-NAND Flash Controller for Realtek RTL9300 SoCs + +maintainers: + - Chris Packham + +description: + The Realtek RTL9300 SoCs have a built in SPI-NAND controller.
