    Subject[PATCH 4.4 28/67] cpufreq: Add Loongson machine dependencies
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: James Hogan <jhogan@kernel.org>


    [ Upstream commit 0d307935fefa6389eb726c6362351c162c949101 ]

    The MIPS loongson cpufreq drivers don't build unless configured for the
    correct machine type, due to dependency on machine specific architecture
    headers and symbols in machine specific platform code.

    More specifically loongson1-cpufreq.c uses RST_CPU_EN and RST_CPU,
    neither of which is defined in asm/mach-loongson32/regs-clk.h unless
    CONFIG_LOONGSON1_LS1B=y, and loongson2_cpufreq.c references
    loongson2_clockmod_table[], which is only defined in
    arch/mips/loongson64/lemote-2f/clock.c, i.e. when
    CONFIG_LEMOTE_MACH2F=y.

    Add these dependencies to Kconfig to avoid randconfig / allyesconfig
    build failures (e.g. when based on BMIPS which also has a cpufreq
    driver).
