Subject: [PATCH v2 1/5] dt-bindings: update device tree binding for Allwinner PRCM CCUs
Date: Thu, 16 Mar 2017 01:28:04 +0800	[thread overview]
Message-ID: <20170315172808.64011-2-icenowy@aosc.xyz> (raw)
In-Reply-To: <20170315172808.64011-1-icenowy-ymACFijhrKM@public.gmane.org>

Many Allwinner SoCs after A31 have a CCU in PRCM block.

Give the ones on H3 and A64 compatible strings.

Signed-off-by: Icenowy Zheng <icenowy-ymACFijhrKM@public.gmane.org>
---
Changes in v2:
- Add iosc for R_CCU's on H3/A64. (A31, A23 and A33 seem to have different
  clock for mux 3 of ar100 clk. Investgations are needed for them.)
