Subject: dt-bindings: firmware: xilinx: Add conditional pinctrl schema
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26dfe3a6d9a9ca055d5c8a2a40e1838ef09aff5e;p=thirdparty%2Fkernel%2Flinux.git

dt-bindings: firmware: xilinx: Add conditional pinctrl schema

Updates the Device Tree bindings for Xilinx firmware by introducing
conditional schema references for the pinctrl node.

Previously, the pinctrl node directly referenced
xlnx,zynqmp-pinctrl.yaml. However, this patch modifies the schema to
conditionally apply the correct pinctrl schema based on the compatible
property. Specifically:
- If compatible contains "xlnx,zynqmp-pinctrl", reference
  xlnx,zynqmp-pinctrl.yaml.
- If compatible contains "xlnx,versal-pinctrl", reference
  xlnx,versal-pinctrl.yaml.

Additionally, an example entry for "xlnx,versal-pinctrl" has been
added under the examples section.
