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.
