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.
