+System reset
+------------
+
+Required properties:
+- compatible: should be one of the following:
+ "socionext,uniphier-sld3-reset" - for PH1-sLD3 SoC.
+ "socionext,uniphier-ld4-reset" - for PH1-LD4 SoC.
+ "socionext,uniphier-pro4-reset" - for PH1-Pro4 SoC.
+ "socionext,uniphier-sld8-reset" - for PH1-sLD8 SoC.
+ "socionext,uniphier-pro5-reset" - for PH1-Pro5 SoC.
+ "socionext,uniphier-pxs2-reset" - for ProXstream2/PH1-LD6b SoC.
+ "socionext,uniphier-ld11-reset" - for PH1-LD11 SoC.
+ "socionext,uniphier-ld20-reset" - for PH1-LD20 SoC.
+- #reset-cells: should be 1.
