Reformatted compatibility strings to one valid combination on each line. 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 <sagar.kadam@sifive.com> --- Documentation/devicetree/bindings/i2c/i2c-ocores.txt | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-)
