Add the Device Tree binding documentation for the non-standard BCM63xx UART hardware block found in the BCM63xx DSL SoCs. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> --- Changes in v2: - update the compatible property to be "brcm,bcm6345-uart" as suggested - reword the clocks and clock-names properties based on feedback from Mark .../devicetree/bindings/serial/bcm63xx-uart.txt | 27 ++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 Documentation/devicetree/bindings/serial/bcm63xx-uart.txt
