commit b2f00c2db71aeffed23936d0f79439236176b1a9 Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Mon May 26 04:35:48 2014 +1000
superio/winbond/w83627ehg: Remove pnp_enter symbol from global
Part 2/2: Break this poor relationship between boards and Super I/O support to be more well-defined. The Super I/O pnp_entry/exit functions should not be exposed into the global name-space, rather should be static-local.
Provide Winbond w83627eh(f/g) input clock rate selection. This is selected by bit 6 of CR 24h by mask & 0xbf map (1 = 48MHz default) -> (0 = 24MHz), see data-sheet page 98.
