+PDC Global
+======================================
+
+This binding describes a reset-controller found on PDC-Global (Power Domain
+Controller) block for Qualcomm Technologies Inc SDM845 SoCs.
+
+Required properties:
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be:
+ "qcom,sdm845-pdc-global"
+
+- reg:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: must specify the base address and size of the register
+ space.
+
+- #reset-cells:
+ Usage: required
+ Value type: <uint>
+ Definition: must be 1; cell entry represents the reset index.
+
+Example:
+
+pdc_reset: reset-controller@b2e0000 {
+ compatible = "qcom,sdm845-pdc-global";
+ reg = <0xb2e0000 0x20000>;
+ #reset-cells = <1>;
+};
+
+PDC reset clients
+======================================
+
+Device nodes that need access to reset lines should
+specify them as a reset phandle in their corresponding node as
+specified in reset.txt.
+
+For a list of all valid reset indices see
+<dt-bindings/reset/qcom,sdm845-pdc.h>
+
+Example:
+
+modem-pil@4080000 {
+ ...
+
+ resets = <&pdc_reset PDC_MODEM_SYNC_RESET>;
+ reset-names = "pdc_reset";
+
+ ...
+};
