2 I2C device driver binding control from user-space in old kernels
10 Up to kernel 2.6.32, many I2C drivers used helper macros provided by
11 <linux/i2c.h> which created standard module parameters to let the user
12 control how the driver would probe I2C buses and attach to devices. These
17 With the conversion of the I2C subsystem to the standard device driver
18 binding model, it became clear that these per-module parameters were no
