[PATCH v4 0/5] Add USB nodes for am43xx epos and gp evm

[George Cherian]

The patch series adds USB dt nodes for am43xx epos and gp evm
Boot tested with linux-next + Tony's omap-for-v3.15/dt

Changes from v1 -> v2
	* Reorder "doc: Add "ti,am437x-dwc3" comaptible for dwc3 glue"
	* Address v1 coments on "ARM: dts: AM4372: Add USB nodes"  

Changes from v2 -> v3
	* Removed unwanted dwc3_1 and dwc3_2 nodes from am437x-gp-evm.dts 
	  and am43x-epos-evm.dts 

Changes from v3 -> v4
	* Refreshed on top of Tony's omap-for-v3.15/dt tree
	* Added usb_phy0_always_on_clk32k and usb_phy1_always_on_clk32k Patch 2
	* Used the above clocks in Patch 3 
	* Patch 4 and 5 edited the unwanted portions of commit log
