d3daba10f1 ARM: AM43xx: EPOS_EVM: Add support for LPDDR2
AM4372 EPOS EVM has 1GB LPDDR2(Part no: MT42L256M32D2LG-25 WT:A)
Adding LPDDR2 init sequence and register details for the same.
Below is the brief description of LPDDR2 init sequence:
-> Configure VTP
-> Configure DDR IO settings
-> Disable initialization and refreshes until EMIF registers are programmed.
-> Program Timing registers
-> Program PHY control and Temp alert and ZQ config registers.
-> Enable initialization and refreshes and configure SDRAM CONFIG register
-> Wait till initialization is complete and the configure MR registers.

cf04d0326b ARM: AM43xx: clocks: Update DPLL details
Updating the Multiplier and Dividers value for all DPLLs.
Safest OPP is read from DEV ATTRIBUTE register. Accoring to the value
returned the MPU DPLL is locked.
At different OPPs follwoing are the MPU locked frequencies.
OPP50	300MHz
OPP100	600MHz
OPP120	720MHz
OPPTB	800MHz
OPPNT	1000MHz
According to the latest DM following is the OPP table dependencies:
	VDD_CORE 	VDD_MPU
	OPP50		OPP50
	OPP50 		OPP100
	OPP100		OPP50
	OPP100		OPP100
	OPP100		OPP120
So at different OPPs of MPU it is safest to lock CORE at OPP_NOM.
Following are the DPLL locking frequencies at OPP NOM:
Core locks at 1000MHz
Per locks at 960MHz
LPDDR2 locks at 266MHz
DDR3 locks at 400MHz

Touching AM33xx files also to get DPLL values specific to board but no
functionality difference.

3d799c7f5e usb: am437x: Add support for am437x xhci USB host
Add the support for the am437x xhci usb host.

The xHCI host on AM437 is connected to a usb2 phy so need to
add support to enable those clocks.
