Subject[PATCH v2 3/3] reset: uniphier: add analog amplifiers reset control
Date
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.

+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 {
+ compatible = "socionext,uniphier-ld11-adamv",
+ "simple-mfd", "syscon";
+ reg = <0x57920000 0x1000>;
