The Clocking Wizard for Versal adaptive compute acceleration platforms generates multiple configurable number of clock outputs. Add device tree binding for Versal clocking wizard support. Signed-off-by: Shubhrajyoti Datta <shubhrajyoti.datta@xxxxxxx> --- Changes in v3: rename the clocks to clk_in1 and s_axi_clk dt Changes in v2: rename the clocks clk_in1 to in1 and s_axi_clk to s_axi in dt .../clock/xlnx,versal-clk-wizard.yaml | 65 +++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/xlnx,versal-clk-wizard.yaml diff --git a/Documentation/devicetree/bindings/clock/xlnx,versal-clk-wizard.yaml b/Documentation/devicetree/bindings/clock/xlnx,versal-clk-wizard.yaml new file mode 100644 index 000000000000..cd3c329ddd29 --- /dev/null +++ b/Documentation/devicetree/bindings/clock/xlnx,versal-clk-wizard.yaml @@ -0,0 +1,65 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/clock/xlnx,versal-clk-wizard.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Xilinx Versal clocking wizard + +maintainers: + - Shubhrajyoti Datta <shubhrajyoti.datta@xxxxxxx> + +description: + The clocking wizard is a soft ip clocking block of Xilinx Versal.
