+Aspeed JTAG driver for ast2400 and ast2500 SoC
+
+Required properties:
+- compatible:		Should be one of
+      - "aspeed,ast2400-jtag"
+      - "aspeed,ast2500-jtag"
+- reg			contains the offset and length of the JTAG memory
+			region
+- clocks		root clock of bus, should reference the APB
+			clock in the second cell
+- resets		phandle to reset controller with the reset number in
+			the second cell
+- interrupts		should contain JTAG controller interrupt
+
+Example:
+jtag: jtag@1e6e4000 {
+	compatible = "aspeed,ast2500-jtag";
+	reg = <0x1e6e4000 0x1c>;
+	clocks = <&syscon ASPEED_CLK_APB>;
+	resets = <&syscon ASPEED_RESET_JTAG_MASTER>;
+	interrupts = <43>;
+};
