[PATCH 2/4] mmc: tmio: add references to bit defines in the header

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

 



When defining bits, make sure we always have a reference to the register
they belong to. For now, renaming all bits properly seems too intrusive,
so at least make sure we have proper documentation.
