# W1 subsystem configuration
menu "1-Wire support"
config W1
bool "Enable 1-wire controllers support"
default no
depends on DM
Support for the Dallas 1-Wire bus.
if W1
config W1_GPIO
bool "Enable 1-wire GPIO bitbanging"
default no
depends on DM_GPIO
Emulate a 1-wire bus using a GPIO.
config W1_MXC
bool "Enable 1-wire controller on i.MX processors"
default no
depends on ARCH_MX25 || ARCH_MX31 || ARCH_MX5
Support the one wire controller found in some members of the NXP
i.MX SoC family.
There are currently two silicon variants:
V1: i.MX21, i.MX27, i.MX31, i.MX51
V2: i.MX25, i.MX35, i.MX50, i.MX53
Newer i.MX SoCs such as the i.MX6 do not have one wire controllers.
The driver supports both silicon variants.
