    Subject[PATCH v2 0/3] sh: make early_platform code SuperH-specific
    Date
    I recently started a discussion about the need for a proper early device
    probing mechanism[1]. One that would be based on real platform drivers
    and support both platform data and device tree.

    While we're far from reaching any consensus on the implementation, Arnd
    suggested that I start off by moving the SuperH-specific early platform
    drivers implementation to arch/sh[2].

    This series is the first attempt at making way for a new, less hacky
    implementation.

    The first patch removes the last instance of a non-sh driver using the
    early_platform API. It can be removed since ARM no longer probes early
    drivers.

    The second patch moves all the early_platform code to arch/sh.

    The last patch prefixes all early_platform symbols with 'sh_'.

    v1 -> v2:
    - certain drivers are compiled for arm/mach-shmobile too - we need to
    add ifdefs for CONFIG_SUPERH around early_platform calls

    clocksource: timer-ti-dm: remove the early platform driver
    registration
    platform: move the early platform device support to arch/sh
    sh: add the sh_ prefix to early platform symbols
