From: "Philip A. Prindeville" <philipp@xxxxxxxxxxxxxxxxxxxxx>
Subject: geos: platform driver for Geos and Geos2 single-board computers
Platform driver for Traverse Technologies Geos and Geos2 single-board
computers. Uses SMBIOS to identify platform. Based on progressive
revisions of the leds-net5501 driver that was rewritten by Ed Wildgoose as
a platform driver.
Supports GPIO-based LEDs (3) and 1 polled button which is typically used
for a soft reset.
