+Socionext UniPhier HSC (High-speed Stream Controller)
+
+The Socionext UniPhier HSC subsystem consists of MPEG2-TS input/output and
+demultiplexer cores in the same register space.
+
+This interface supports TS serial signals (clock, valid, sync, data) from
+external demodulators.
+
+Required properties:
+- compatible : should be one of the following:
+ "socionext,uniphier-ld11-hsc"
+ "socionext,uniphier-ld20-hsc"
+- reg : offset and length of the register set for the device.
+- interrupts : should contain DMA and TSI error interrupt.
+- pinctrl-names : should be "default".
+- pinctrl-0 : defined TS serial signal pins for external demodulators.
+- clock-names : should include the following entries:
+ "hsc", "stdmac"
+- clocks : a list of phandle, should contain an entry for each
+ entry in clock-names.
+- reset-names : should include the following entries:
+ "hsc", "stdmac"
+- resets : a list of phandle, should contain an entry for each
+ entry in reset-names.
+
+Example:
+ hsc {
+ compatible = "socionext,uniphier-ld20-hsc";
+ reg = <0x5c000000 0x100000>;
+ interrupts = <0 100 4>, <0 101 4>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_hscin2_s>,
+ <&pinctrl_hscin3_s>;
+ clock-names = "stdmac", "hsc";
+ clocks = <&sys_clk 8>, <&sys_clk 9>;
+ reset-names = "stdmac", "hsc";
+ resets = <&sys_rst 8>, <&sys_rst 9>;
+ };
