+Subject: [PATCH 1/1] geos: Platform driver for Geos and Geos2 single-board
+ computers.
+
+Trivial 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.
