Martin Fuzzey a2e99a71b2 w1: Add driver for i.MX bus master controller
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).

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.
