Can you please confirm this? The documentation for GCC says that the
incoming sleep clock is 32000Hz.

Bjorn,
I checked the internal documents and it is derived from the PMIC as
32.7645KHz. I rounded off it to 32768Hz. Looks like GCC documentation
is not up-to-date.
All these information is available in the link
https://lore.kernel.org/all/e2a447f8-6024-0369-f698-2027b6edcf9e@xxxxxxxxxxxxxx/
Please let me know if you need any further information.
Thanks,
Kathiravan T.
Bjorn,
Gentle Ping.
Thanks,
Kathiravan T.
