FYI on this one patch - it won't be applied to the Tegra tree until
after Prashant's common clock framework changes are applied. As such, it
will need some rework once those patches are applied, or perhaps won't
even be relevant any more; see below.

I assume the only reason to add AUXDATA is to give the device a specific
name, which will then match the driver name in the clock driver:

If so, this shouldn't be needed once the common clock framework patches
are applied, since all device clocks will be retrieved from device tree,
and hence the device name will be irrelevant; the phandle in device tree
is all that will matter.
