Commit Message

Add a reset line for analog signal amplifier core (ADAMV) on
UniPhier LD11/LD20 SoCs.

Signed-off-by: Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com>

Changes for v2:
  - ID changes to 0 because ADAMV reset controller independents
    from other reset controllers.
  - Add DT-binding documents.

Thank you, applied all three to the reset/next branch with Masahiro's
acks.

+Analog signal amplifier reset
+-----------------------------

+Required properties:
+- compatible: should be one of the following:
+    "socionext,uniphier-ld11-adamv-reset" - for LD11 SoC
+    "socionext,uniphier-ld20-adamv-reset" - for LD20 SoC
+- #reset-cells: should be 1.

+Example:
+
+	adamv@57920000 {

+			     "simple-mfd", "syscon";
