28.Sh NAME
29.Nm chromebook_platform
30.Nd support driver for hardware on various Chromebook models
31.Sh SYNOPSIS
32To compile this driver into the kernel, place the following lines into
33the kernel configuration file:
34.Bd -ragged -offset indent
35.Cd "device chromebook_platform"
36.Ed
37.Pp
38Alternatively, to load the driver as a module at boot time, place the following line in
39.Xr loader.conf 5 :
40.Bd -literal -offset indent
41chromebook_platform_load="YES"
42.Ed
43.Sh DESCRIPTION
44The
45.Nm
46driver provides automatic configuration for devices that cannot be enumerated
47or safely probed.
48In particular, I2C peripherals are different from model to model.
49.Nm
50has a model-specific information about the I2C peripherals, their drivers,
51their bus attachments and slave addresses.
52.Pp
53Note that
54.Nm
55does not load driver modules for the peripherals.
56Those have to be compiled into the kernel or loaded separately.
