+Cortina Systems Gemini timer
+
+This timer is embedded in the Cortina Systems Gemini SoCs.
+
+Required properties:
+
+- compatible : Must be "cortina,gemini-timer"
+- reg : Should contain registers location and length
+- interrupts : Should contain the three timer interrupts with
+ flags for rising edge
+- syscon : a phandle to the global Gemini system controller
+
+Example:
+
+timer@43000000 {
+ compatible = "cortina,gemini-timer";
+ reg = <0x43000000 0x1000>;
+ interrupts = <14 IRQ_TYPE_EDGE_RISING>, /* Timer 1 */
+ <15 IRQ_TYPE_EDGE_RISING>, /* Timer 2 */
+ <16 IRQ_TYPE_EDGE_RISING>; /* Timer 3 */
+ syscon = <&syscon>;
+};

+* Renesas OS Timer (OSTM)
+
+The OSTM is a multi-channel 32-bit timer/counter with fixed clock
+source that can operate in either interval count down timer or free-running
+compare match mode.
+
+Channels are independent from each other.
+
+Required Properties:
+
+ - compatible: must be one or more of the following:
+ - "renesas,r7s72100-ostm" for the r7s72100 OSTM
+ - "renesas,ostm" for any OSTM
+ This is a fallback for the above renesas,*-ostm entries
+
+ - reg: base address and length of the register block for a timer channel.
+
+ - interrupts: interrupt specifier for the timer channel.
+
+ - clocks: clock specifier for the timer channel.
+
+Example: R7S72100 (RZ/A1H) OSTM node
+
+ ostm0: timer@fcfec000 {
+ compatible = "renesas,r7s72100-ostm", "renesas,ostm";
+ reg = <0xfcfec000 0x30>;
+ interrupts = <GIC_SPI 102 IRQ_TYPE_EDGE_RISING>;
+ clocks = <&mstp5_clks R7S72100_CLK_OSTM0>;
+ power-domains = <&cpg_clocks>;
+ };
