Subject: [PATCH v3 3/3] dt-bindings: clock: Add loongson-1 clock bindings
Date: Fri,  1 Feb 2019 14:35:40 +0800	[thread overview]
Message-ID: <20190201063540.19636-4-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20190201063540.19636-1-jiaxun.yang@flygoat.com>

Loongson-1 is a series of MIPS MCUs.
This patch add the clock bindings for loongson-1b and
loongson-1c clock subsystem.

+* Clock bindings for Loongson-1 MCUs
+
+Required properties:
+- compatible: must contain one of the following compatibles:
+                - "loongson,ls1b-clock"
+                - "loongson,ls1c-clock"
+
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- clocks: list of input clocks
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/ls1c-clock.h
+or include/dt-bindings/clock/ls1b-clock.h for the full list of clocks.
