  9. help
  10. If you say yes to this option, support will be included for an
  11. I2C multimaster arbitration scheme using GPIOs and a challenge &
  12. response mechanism where masters have to claim the bus by asserting
  13. a GPIO.
  14. This driver can also be built as a module. If so, the module
  15. will be called i2c-arb-gpio-challenge.
  16. config I2C_MUX_GPIO

  18. depends on GPIOLIB
  19. help
  20. If you say yes to this option, support will be included for a
  21. GPIO based I2C multiplexer. This driver provides access to
  22. I2C busses connected through a MUX, which is controlled
  23. through GPIO pins.
  24. This driver can also be built as a module. If so, the module
  25. will be called i2c-mux-gpio.
  26. config I2C_MUX_PCA9541

  28. help
  29. If you say yes here you get support for the NXP PCA9541
  30. I2C Master Selector.
  31. This driver can also be built as a module. If so, the module
  32. will be called i2c-mux-pca9541.
  33. config I2C_MUX_PCA954x
  34. tristate "Philips PCA954x I2C Mux/switches"
  35. help
  36. If you say yes here you get support for the Philips PCA954x
  37. I2C mux/switch devices.
  38. This driver can also be built as a module. If so, the module
  39. will be called i2c-mux-pca954x.
  40. config I2C_MUX_PINCTRL
  41. tristate "pinctrl-based I2C multiplexer"
  42. depends on PINCTRL
  43. help
  44. If you say yes to this option, support will be included for an I2C
  45. multiplexer that uses the pinctrl subsystem, i.e. pin multiplexing.
  46. This is useful for SoCs whose I2C module's signals can be routed to
  47. different sets of pins at run-time.
  48. This driver can also be built as a module. If so, the module will be
  49. called pinctrl-i2cmux.
