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 under optional property list as this 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 Reviewed-by: Rob Herring --- Documentation/devicetree/bindings/i2c/i2c-ocores.txt | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/Documentation/devicetree/bindings/i2c/i2c-ocores.txt b/Documentation/devicetree/bindings/i2c/i2c-ocores.txt index 17bef9a..6b25a80 100644 --- a/Documentation/devicetree/bindings/i2c/i2c-ocores.txt +++ b/Documentation/devicetree/bindings/i2c/i2c-ocores.txt @@ -1,9 +1,13 @@ Device tree configuration for i2c-ocores Required properties: -- compatible : "opencores,i2c-ocores" or "aeroflexgaisler,i2cmst" +- compatible : "opencores,i2c-ocores" + "aeroflexgaisler,i2cmst" + "sifive,fu540-c000-i2c", "sifive,i2c0" + For Opencore based I2C IP block reimplemented in + FU540-C000 SoC.
