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@codeaurora....
Please let me know if you need any further information.
Thanks,
Kathiravan T.
