Tegra194 XUSB host controller has rearranged mailbox registers. This
commit makes mailbox registers address a part of "soc" data so that
xhci-tegra driver can be used for Tegra194.

I'd perhaps reformulate the subject a little to be something like:

	xhci: tegra: Parameterize mailbox register addresses

Two other minor comments below.

Perhaps make these unsigned int (or unsigned long). Making these
explicitly sized variables suggests (at least to me) that they are
register values, whereas they really are offsets. So I prefer to use
"unsized" types to distinguish between register offsets and values.

You're already giving these registers names via the new parameters, so I
don't think we need the symbolic names. This usually just leads to weird
things like:

	#define XUSB_CFG_ARU_MBOX_CMD_T194 ...
	#define XUSB_CFG_ARU_MBOX_DATA_IN_T194 ...
	#define XUSB_CFG_ARU_MBOX_DATA_OUT_T194 ...
	#define XUSB_CFG_ARU_MBOX_OWNER_T194 ...

	.mbox = {
		.cmd = XUSB_CFG_ARU_MBOX_CMD_T194,
		.data_in = XUSB_CFG_ARU_MBOX_DATA_IN_T194,
		.data_out = XUSB_CFG_ARU_MBOX_DATA_OUT_T194,
		.owner = XUSB_CFG_ARU_MBOX_OWNER_T194,
	},

Just remove the symbolic names and use the literal address in the
structure definition.

Thanks for review. I will modify accordingly and submit again.
