Two variants of controllers are supported: V1 (bitwise only) found in i.MX21, i.MX27, i.MX31, i.MX51 V2 (byte operations) found in i.MX25, i.MX35, i.MX50, i.MX53 Only tested on i.MX53 hardware but in both modes (by modifying the device tree).

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.
