    Subject[PATCH v2 0/5] patches to settle i8042 with Intel MID platforms
    From: Feng Tang <>

    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.


    * only call x86_platforms.i8042_detect() for x86 platforms

    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
