DT binding for the TI DA8xx/OMAP-L1x/AM17xx/AM18xx MUSB driver. Signed-off-by: Petr Kulhavy <petr@xxxxxxxxx> --- v1: <initial> v2: - using standard properties "dr_mode", "mentor,power", "mentor,num-eps", "mentor,multipoint", "mentor,ram-bits" - using "ti," prefix instead of "da8xx," for specific property names - no wildcards in compatibility string v3: - added "reg", "interrupts" and "interrupt-names" properties - wildcards in compatibility string v4: - compatibility string set to "ti,da830-musb" - "mentor,num-eps", "mentor,multipoint", "mentor,ram-bits" properties removed and hardcoded - "ti,phy20-clkmux-cfg" renamed to "ti,phy20-clkmux-pll" and changed to boolean - removed "ti,hwmods" v5: - "ti,phy20-refclock-frequency" property made mandatory v6: - using "ti,usb2-phy-" prefix instead of "ti,phy20-" for the specific properties v7: - removed the "mentor,power" property; hard coded to 500mA in the code v8: - "ti,usb2-phy-refclock-frequency" renamed to "ti,usb2-phy-refclock-hz" and description amended - "ti,usb2-phy-clkmux-pll" changed to "ti,usb2-phy-clkmux-refclkin" to reflect the more common case - USB maximum power modelled via a regulator "vbus-supply" v9: <no change> v10: <no change> .../devicetree/bindings/usb/da8xx-usb.txt | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/da8xx-usb.txt diff --git a/Documentation/devicetree/bindings/usb/da8xx-usb.txt b/Documentation/devicetree/bindings/usb/da8xx-usb.txt new file mode 100644 index 0000000..a6eda5b --- /dev/null +++ b/Documentation/devicetree/bindings/usb/da8xx-usb.txt @@ -0,0 +1,45 @@ +TI DA8xx MUSB +~~~~~~~~~~~~~ +For DA8xx/OMAP-L1x/AM17xx/AM18xx platforms. + +Required properties: +~~~~~~~~~~~~~~~~~~~~ + - compatible : Should be set to "ti,da830-musb". + + - reg: Offset and length of the USB controller register set. + + - interrupts: The USB interrupt number. + + - interrupt-names: Should be set to "mc". + + - dr_mode: The USB operation mode.
