Subject: [PATCH v2 2/4] arm64: dts: r8a7796: Add reset control properties
Date: Thu, 16 Mar 2017 15:07:24 +0100 [thread overview]
Message-ID: <1489673246-11015-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1489673246-11015-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>
Add properties to describe the reset topology for on-SoC devices:
- Add the "#reset-cells" property to the CPG/MSSR device node,
- Add resets and reset-names properties to the various device nodes.
This allows to reset SoC devices using the Reset Controller API.
Note that all resets added match the corresponding module clocks.
Signed-off-by: Geert Uytterhoeven <geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>
---
v2:
- Add reset properties to recently added device nodes (i2c_dvfs,
hscif[0-4], scif[01345], tsc).
