#1710458 — [PATCH v2 3/3] reset: uniphier: add analog amplifiers reset control

Subject[PATCH v2 3/3] reset: uniphier: add analog amplifiers reset control
Message-ID<udX4e-5hn-7@gated-at.bofh.it>
In reply to#1710456
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.
