32 .Nd Intel(R) fourth generation mobile CPU integrated I2C driver
34 To compile this driver into the kernel, place the following lines into
35 the kernel configuration file:
36 .Bd -ragged -offset indent
41 Alternatively, to load the driver as a module at boot time, place the following line in
43 .Bd -literal -offset indent
49 driver provides access to peripherals attached to an I2C controller.
52 supports the I2C controllers found in fourth generation Intel(R) Core(TM)
53 processors based on the mobile U-processor line for intelligent systems.
54 This includes the i7-4650U, i5-4300U, i3-4010U, and 2980U.
58 variables are available:
59 .Bl -tag -width "debug.ig4_dump"
61 This sysctl is a zero-based bit mask.
62 When any of the bits are set, a register dump is printed for
63 every I2C transfer on an
65 device with the same unit number.
74 driver was written for DragonFly BSD by
76 and subsequently ported to
