The RPMh clock driver assumes that the xo_board clock is named
"xo_board", not "xo-board". Add a "clock-output-names" property to
the device tree to get the right name.
Also add the proper speed for the xo-clock as 38400000. This is
internally divided in RPMh clock driver to get "bi_tcxo" at 19200000.
After this change the clock tree in /sys/kernel/debug/clk/clk_summary
looks much better.
NOTES:
- Technically you could argue that this clock could belong in board
.dts files, not in the SoC one. However at the moment it's believed
that 100% of sdm845 boards will have an external clock at 38.4. It
can always be moved later if necessary.
- We could rename the "xo-board" device tree node to "xo_board" to
achieve the same effect as this patch. Presumably device-tree folks
would rather keep node names using dashes though.
- We could change the RPMh clock driver to use a dash to achieve the
same effect as this patch, but all other clocks in the clock tree
use underscores. It seems silly to change just this one.
