    regmap: select REGMAP if REGMAP_MMIO and REGMAP_IRQ enabled · 5784ee4d

    The regmap_mmio and regmap_irq depend on regmap core, if not select,
    we may not compile regmap core and meet compiling errors as follows
    if REGMAP_MMIO is selected by client drivers:
    drivers/mfd/syscon.c:94:15: error: variable 'syscon_regmap_config' has initializer but incomplete type
