Signed-off-by: Brad Larson Reviewed-by: Krzysztof Kozlowski --- v14 changes: - Change GPL-2.0-only or BSD-2-Clause to GPL-2.0-only OR BSD-2-Clause v11 changes: - Fixed the compatible which should have stayed as 'amd,pensando-elba-ctrl', the commit message, and the filename - Reference spi-peripheral-props - Delete spi-max-frequency - Remove num-cs from example v10 changes: - Property renamed to amd,pensando-ctrl - Driver is renamed and moved to soc/drivers/amd affecting binding - Delete cs property, driver handles device node creation from parent num-cs fixing schema reg error in a different way v9 changes: - Instead of four nodes, one per chip-select, a single node is used with reset-cells in the parent. - No MFD API is used anymore in the driver so it made sense to move this to drivers/spi. - This driver is common for all Pensando SoC based designs so changed the name to pensando-sr.c to not make it Elba SoC specific. - Added property cs for the chip-select number which is used by the driver to create /dev/pensr0. --- .../soc/amd/amd,pensando-elba-ctrl.yaml | 58 +++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/amd/amd,pensando-elba-ctrl.yaml diff --git a/Documentation/devicetree/bindings/soc/amd/amd,pensando-elba-ctrl.yaml b/Documentation/devicetree/bindings/soc/amd/amd,pensando-elba-ctrl.yaml new file mode 100644 index 000000000000..e96978ad1e37 --- /dev/null +++ b/Documentation/devicetree/bindings/soc/amd/amd,pensando-elba-ctrl.yaml @@ -0,0 +1,58 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/soc/amd/amd,pensando-elba-ctrl.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: AMD Pensando Elba SoC Controller + +description: + The AMD Pensando Elba SoC Controller is a SPI connected device with essential + control/status registers accessed on chip select 0.
