Subject: [PATCHv5 4/9] ARM: at91: dt: sam9rl: Device Tree for the at91sam9rlek
Date: Wed, 12 Mar 2014 10:43:40 +0100 [thread overview]
Message-ID: <1394617425-641-5-git-send-email-alexandre.belloni@free-electrons.com> (raw)
In-Reply-To: <1394617425-641-1-git-send-email-alexandre.belloni@free-electrons.com>
Add a device tree for the at91sam9rl-ek. For now it supports:
- MMC
- dbgu
- usart1
- watchdog
- nand
- leds
- buttons
