Sleep clock frequency should be 32768Hz. Lets fix it.

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/[email protected]/
Please let me know if you need any further information.
Thanks,
Kathiravan T.
