From 2e1117d307dba8185a72bac94e57f057e70590ca Mon Sep 17 00:00:00 2001 From: Martin Michlmayr Date: Mon, 7 Jul 2008 21:23:09 +0300 Subject: [ARM] Orion: LED support for HP mv2120 The HP mv2120 has several LEDs that are controlled through gpio. Export the health LED, the red SATA LEDs as well as two gpios that control the brightness of _all_ LEDs to userland. The Ethernet and power LEDs can't be controlled through gpio and the blue SATA LEDs are handled via the SATA driver.
