    ARM: mx5: use generic irq chip pm interface for pm functions on · 010dc8af
    Hui Wang authored
    Two problems exist in the current i.MX5 pm suspend/resume and idle
    functions. The first is the current i.MX5 suspend routine will call
    tzic_enable_wake(1) to set wake source, this will set all enabled
    irq as wake source rather than those wake capable. The second
    is i.MX5 idle will call mx5_cpu_lp_set() to prepare enter low power
    mode, but it forgets to call wfi instruction to enter this mode.
    
    To fix these two problems, using generic irq chip pm interface and
    modify function imx5_idle().
