<p class="Pp">The <code class="Nm">chromebook_platform</code> driver provides
    automatic configuration for devices that cannot be enumerated or safely
    probed. In particular, I2C peripherals are different from model to model.
    <code class="Nm">chromebook_platform</code> has a model-specific information
    about the I2C peripherals, their drivers, their bus attachments and slave
    addresses.</p>
<p class="Pp">Note that <code class="Nm">chromebook_platform</code> does not
    load driver modules for the peripherals. Those have to be compiled into the
    kernel or loaded separately.</p>
