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