  After some initial confusion, we've finally settled how the UFS ref
clocks are used.

The first patch fixes the UFS controller and PHY nodes so that they
reflect the hardware. This one should go in 6.1-rc where the two
previous attempts to address this are heading.

Note this patch depends on first updating the clock driver to reflect
that the device ref clock is fed from CXO. This is needed as the UFS
controller driver requires a valid frequency for the ref clock. A patch
that addresses the this has been submitted, but a v2 is in the works.

The second patch updates the UFS PHY nodes so that they reflect the
fixed UFS PHY binding that is now in linux-next. This one is 6.2
material but depends on first fixing the clocks.

So to summarise the dependency order:

 1. clock driver should be fixed in 6.1-rc
 2. patch 1/2 should go in 6.1-rc (after 1)
 3. patch 2/2 should go in 6.2 (after 1 and 2)
