+description: |
+ Special settings need to be configured by MediaTek DP based on the actual
+ hardware situation. For example, when using a certain brand's docking
+ station for display projection, garbage may appear. Adjusting the specific
+ ssc value can resolve this issue.
+
+properties:
+ status: disabled
+ description: |
+ Since the DP driver has already registered the DP PHY device
+ through mtk_dp_register_phy(), so the status is disabled.
+
+ dp-ssc-setting:
+ - ssc-delta-hbr
+ description: Specific values are set based on the actual HW situation.
+
+required:
+ - status
+ - dp-ssc-setting
+
+examples:
+ - |
+ soc {
+ #address-cells = <2>;
+ #size-cells = <2>;
+
+ phy-dp@1c600000 {
+ status = "disabled";
+ dp-ssc-setting {
+ ssc-delta-hbr = <0x01fe>;
+ }
+ };
