.Dt CHROMEBOOK_PLATFORM 4
|
|
.Os
|
|
.Sh NAME
|
|
.Nm chromebook_platform
|
|
.Nd support driver for hardware on various Chromebook models
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel, place the following lines into
|
|
the kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device chromebook_platform"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
chromebook_platform_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides automatic configuration for devices that cannot be enumerated
|
|
or safely probed.
|
|
In particular, I2C peripherals are different from model to model.
|
|
.Nm
|
|
has a model-specific information about the I2C peripherals, their drivers,
|
|
their bus attachments and slave addresses.
|
|
.Pp
|
|
Note that
|
|
.Nm
|
|
does not load driver modules for the peripherals.
|
|
Those have to be compiled into the kernel or loaded separately.
