Subject: [PATCH] Add attributes neccessary for LED flashes to devicetree/bindings/leds/common.txt
Date: Thu, 20 Nov 2014 14:17:13 +0100 [thread overview]
Message-ID: <20141120131713.GC27527@amd> (raw)
Add attributes neccessary for LED flashes to
devicetree/bindings/leds/common.txt .
This will allow me to add device tree support for adp1653 i2c flash
LED driver, and allow Jacek Anaszewski to add support for more LED
drivers..
