Hi Bjorn, thanks for the review!

"xo_board" is actually the crystal feeding the PMIC with a reference
clock, of interest here is that this is split up in the 2 digital and 3
analog RPM_SMD_CX_{Dx,Ay} clocks. Out of these you have RPM_SMD_CXO_D0
being wired up on the CXO pin on the msm8974.

Back when this was devices we didn't have the means of dealing with
rpmcc as parent to gcc, so you can in gcc_msm8974_probe() find the
registration of a clock "xo" which is a 19.2MHz clock parented by
"xo_board".

As such, the appropriate .name here would be "xo".

Likewise "xo" (or actually "cxo") would be a better name for the
DT-based input clock - and it should point to &rpmcc RPM_SMD_CXO_D0
(iiuc).

I'll try to fix the mentioned issue and send a v2 in series of patches
with other gcc-msm8974 improvements.

Regards,
Ivaylo
