[PATCH 1/4] platform/x86: pmc_atom: Annotate d3_sts register bit defines

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The include/linux/platform_data/x86/pmc_atom.h d3_sts register bit defines
are named after how these bits are used on Bay Trail devices.

On Cherry Trail (CHT) devices some of these bits have a different meaning
according to the datasheet.

At a comment to the defines for bits which have a different meaning
on Cherry Trail devices.
