    soc: fsl: qe: move calls of qe_ic_init out of arch/powerpc/ · 4e0e161d
    Rasmus Villemoes authored
    Having to call qe_ic_init() from platform-specific code makes it
    awkward to allow building the QE drivers for ARM. It's also a needless
    duplication of code, and slightly error-prone: Instead of the caller
    needing to know the details of whether the QUICC Engine High and QUICC
    Engine Low are actually the same interrupt (see e.g. the machine_is()
    in mpc85xx_mds_qeic_init), just let the init function choose the
    appropriate handlers after it has parsed the DT and figured it out. If
    the two interrupts are distinct, use separate handlers, otherwise use
    the handler which first checks the CHIVEC register (for the high
    priority interrupts), then the CIVEC.
    
    All existing callers pass 0 for flags, so continue to do that from the
    new single caller. Later cleanups will remove that argument
    from qe_ic_init and simplify the body, as well as make qe_ic_init into
    a proper init function for an IRQCHIP_DECLARE, eliminating the need to
    manually look up the fsl,qe-ic node.
