configure usb phy transmitter control linux kernel

I am trying to figure out how to set the USB PHY Tx Control Reg via the device tree. If I have to do from userspace, I have to (ideas on this are appreciated also) but I think I should be able to define a register address (0x020CA010 for the i.MX6) and value to be loaded (0xC).

 

The POR default value for D_CAL may be insufficient to allow the on-chip PHY to drive a signal w/ all cables.

 

Any assistance is appreciated.
