Add device tree binding documentation for the Cadence I2C controller. Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> --- Changes in v5: - Document all properties - list clock-names as optional property (driver doesn't use it, though) - use lower case hex digits in 'reg' property - reword description of 'clocks' property - remove implementation specific notes regarding default speed - use #defines for interrupt specifier Changes in v4: - moved adding DT docs into this dedicated patch Changes in v3: None Changes in v2: None --- .../devicetree/bindings/i2c/i2c-cadence.txt | 24 ++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 Documentation/devicetree/bindings/i2c/i2c-cadence.txt
