8 bool "Enable 1-wire controllers support"
12 Support for the Dallas 1-Wire bus.
17 bool "Enable 1-wire GPIO bitbanging"
21 Emulate a 1-wire bus using a GPIO.
24 bool "Enable 1-wire controller on i.MX processors"
26 depends on ARCH_MX25 || ARCH_MX31 || ARCH_MX5
28 Support the one wire controller found in some members of the NXP
30 There are currently two silicon variants:
31 V1: i.MX21, i.MX27, i.MX31, i.MX51
32 V2: i.MX25, i.MX35, i.MX50, i.MX53
33 Newer i.MX SoCs such as the i.MX6 do not have one wire controllers.
35 The driver supports both silicon variants.
