+Subject: [PATCH] leds-bcm6328: support second hw blinking interval
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Right now the driver uses only 3 LED modes:
+0: On
+1: HW Blinking (Interval 1)
+3: Off
+
+However, the controller supports a second HW blinking interval, which results
+in 4 possible LED modes:
+0: On
+1: HW Blinking (Interval 1)
+2: HW Blinking (Interval 2)
+3: Off
