[PATCH 0/5] Support for LEGO MINDSTORTMS EV3

This patch series adds support for LEGO MINDSTORTMS EV3[1]. This is a TI AM1808
based board.

This patch series has been tested working (along with some hacks to fix the
GPIOs) on an EV3.

There are still quite a few additional new drivers that need to be submitted
to get everything working. This patch series just adds support for the parts
that already have mainline kernel drivers.

I have a plan/driver in progress for many of the components[2], but I could use
some advice on a few particulars.

Bluetooth: This needs a driver to sequence a GPIO to take the Bluetooth chip
out of shutdown *after* the Bluetooth clock has been configured and started.
Is there a generic driver that can do this sort of thing? Or, if not, which
subsystem should the new driver go in?

Input and output ports: These ports are capable of hotplugging various devices,
such as sensors and motors. I have written a driver for these that can detect
most devices. I created a new subsystem for this called `lego-port`. However,
I am wondering if the existing phy or extcon subsystems might be a good fit for
this sort of thing.
