From: Sascha Hauer Date: Thu, 20 Sep 2012 13:04:33 +0000 (+0200) Subject: ARM i.MX25: Add devicetree X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5658a68fb578df8c9b9dd3071b2a56bf92c15324;p=openwrt%2Fstaging%2Fblogic.git ARM i.MX25: Add devicetree This adds a i.MX25 dtsi file along with the i.MX25 clock tree documentation. The devicetree should be fairly complete for: - uart - fec - i2c - spi - pwm - nand - gpio - wdog - esdhc - flexcan The more exotic devices currently miss clock bindings.
