+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
+- interrupts should contain JTAG controller interrupt
+
+Example:
+jtag: jtag@1e6e4000 {
+ compatible = "aspeed,ast2500-jtag";
+ reg = <0x1e6e4000 0x1c>;
+ clocks = <&clk_apb>;
+ interrupts = <43>;
+};
