# # W1 subsystem configuration # menu "1-Wire support" config W1 bool "Enable 1-wire controllers support" depends on DM help Support for the Dallas 1-Wire bus. if W1 config W1_GPIO bool "Enable 1-wire GPIO bitbanging" depends on DM_GPIO help Emulate a 1-wire bus using a GPIO. config W1_MXC bool "Enable 1-wire controller on i.MX processors" depends on ARCH_MX31 || ARCH_MX5 help 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. endif endmenu
