From: Feng Tang <feng.tang@intel.com>
Hi All,
Some x86 platforms like intel MID platforms don't have i8042 controllers, and i8042 driver's probe to some non-exist legacy IO ports may hang the MID processor.
Current solution for this is add dependency of SERIO_I8042 over !X86_MRST, then if we build a x86 kernel image with X86_MRST=y, it won't have i8042 driver support over common x86 platforms.
So we add a i8042 pre-detect hook into x86_platforms ops, so that i8042 driver can use it to run-time judge whether to go on with probe process.
Please review these patches.
Thanks, Feng
Changelog: v2: * only call x86_platforms.i8042_detect() for x86 platforms
---------------- Feng Tang (5): x86: add i8042 pre-detection hook to x86_platform_ops x86, mrst: add i8042_detect API for Moorestwon platform Revert "Input: do not force selecting i8042 on Moorestown" Revert "Input: fixup X86_MRST selects" input: i8042 - add runtime check in x86's i8042_platform_init
