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.

Regards,
Bjorn

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.org/

Please let me know if you need any further information.

Thanks,

Kathiravan T.
