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

+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. Should be one of "host", "peripheral" or
"otg".
+
+ - ti,usb2-phy-refclock-frequency : Integer. Defines the USB 2.0 PHY reference
clock input
+ frequency in Hz in case the clock is generated by the internal PLL.
Didn't you say it's needed in the case of external clock anyway?
+ Supported values are 12MHz, 13MHz, 19.2MHz, 20MHz, 24MHz, 26MHz, 38.4MHz,
40MHz, 48MHz
