regmap: select REGMAP if REGMAP_MMIO and REGMAP_IRQ enabled
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 drivers/mfd/syscon.c:95:2: error: unknown field 'reg_bits' specified in initializer drivers/mfd/syscon.c:95:2: warning: excess elements in struct initializer [enabled by default] drivers/mfd/syscon.c:95:2: warning: (near initialization for 'syscon_regmap_config') [enabled by default] drivers/mfd/syscon.c:96:2: error: unknown field 'val_bits' specified in initializer drivers/mfd/syscon.c:96:2: warning: excess elements in struct initializer [enabled by default] drivers/mfd/syscon.c:96:2: warning: (near initialization for 'syscon_regmap_config') [enabled by default] drivers/mfd/syscon.c:97:2: error: unknown field 'reg_stride' specified in initializer drivers/mfd/syscon.c:97:2: warning: excess elements in struct initializer [enabled by default] drivers/mfd/syscon.c:97:2: warning: (near initialization for 'syscon_regmap_config') [enabled by default] drivers/mfd/syscon.c: In function 'syscon_probe': drivers/mfd/syscon.c:124:2: error: invalid use of undefined type 'struct regmap_config' drivers/mfd/syscon.c:125:2: error: implicit declaration of function 'devm_regmap_init_mmio' [-Werror=implicit-function-declaration] drivers/mfd/syscon.c:125:17: warning: assignment makes pointer from integer without a cast [enabled by default] cc1: some warnings being treated as errors drivers/mfd/Kconfig: config MFD_SYSCON bool "System Controller Register R/W Based on Regmap" depends on OF select REGMAP_MMIO help Select this option to enable accessing system control registers via regmap.
