Krzysztof Kozlowski 9fe58ecd1e mux: mmio: Fix missing CONFIG_REGMAP_MMIO 
MMIO mux uses now regmap_init_mmio(), so one way or another
CONFIG_REGMAP_MMIO should be enabled, because there are no stubs for
!REGMAP_MMIO case:

  ERROR: modpost: "__regmap_init_mmio_clk" [drivers/mux/mux-mmio.ko] undefined!

Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202505150312.dYbBqUhG-lkp@intel.com/
Fixes: 61de83fd82 ("mux: mmio: Do not use syscon helper to build regmap")

Multiplexer devices

config MULTIPLEXER tristate

menu "Multiplexer drivers" depends on MULTIPLEXER

config MUX_ADG792A tristate "Analog Devices ADG792A/ADG792G Multiplexers" depends on I2C help ADG792A and ADG792G Wide Bandwidth Triple 4:1 Multiplexers

  The driver supports both operating the three multiplexers in
  parallel and operating them independently.

  To compile the driver as a module, choose M here: the module will
  be called mux-adg792a.

config MUX_ADGS1408 tristate "Analog Devices ADGS1408/ADGS1409 Multiplexers" depends on SPI help ADGS1408 8:1 multiplexer and ADGS1409 double 4:1 multiplexer switches.

  To compile the driver as a module, choose M here: the module will
  be called mux-adgs1408.

config MUX_GPIO tristate "GPIO-controlled Multiplexer" depends on GPIOLIB || COMPILE_TEST help GPIO-controlled Multiplexer controller.

  The driver builds a single multiplexer controller using a number
  of gpio pins. For N pins, there will be 2^N possible multiplexer
  states. The GPIO pins can be connected (by the hardware) to several
  multiplexers, which in that case will be operated in parallel.

  To compile the driver as a module, choose M here: the module will
  be called mux-gpio.

config MUX_MMIO tristate "MMIO/Regmap register bitfield-controlled Multiplexer" depends on OF select REGMAP_MMIO help MMIO/Regmap register bitfield-controlled Multiplexer controller.

  The driver builds multiplexer controllers for bitfields in either
  a syscon register or a driver regmap register. For N bit wide
  bitfields, there will be 2^N possible multiplexer states.

  To compile the driver as a module, choose M here: the module will
  be called mux-mmio.
