[PATCH v5 1/3] dt-bindings: i2c: extend existing opencore bindings.
Add FU540-C000 specific device tree bindings to already available i2-ocores file. This device is available on HiFive Unleashed Rev A00 board. Move interrupt and interrupt parents under optional property list as these can be optional. The FU540-C000 SoC from sifive, has an Opencore's I2C block reimplementation. The DT compatibility string for this IP is present in HDL and available at. https://github.com/sifive/sifive-blocks/blob/master/src/main/scala/devices/i2c/I2C.scala#L73 Signed-off-by: Sagar Shrikant Kadam --- Documentation/devicetree/bindings/i2c/i2c-ocores.txt | 7 ++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/i2c/i2c-ocores.txt b/Documentation/devicetree/bindings/i2c/i2c-ocores.txt index 17bef9a..b73960e 100644 --- a/Documentation/devicetree/bindings/i2c/i2c-ocores.txt +++ b/Documentation/devicetree/bindings/i2c/i2c-ocores.txt @@ -2,8 +2,11 @@ Device tree configuration for i2c-ocores Required properties: - compatible : "opencores,i2c-ocores" or "aeroflexgaisler,i2cmst" +"sifive,fu540-c000-i2c" or "sifive,i2c0". + for Opencore based I2C IP block reimplemented in + FU540-C000 SoC.Please refer sifive-blocks-ip-versioning.txt + for additional details. - reg : bus address start and address range size of device -- interrupts : interrupt number - clocks : handle to the controller clock; see the note below.
