From ec6754a7b9e90a1eba7f3b2812003bb51d3dcf30 Mon Sep 17 00:00:00 2001 From: Jean-Christophe PLAGNIOL-VILLARD Date: Thu, 5 Jul 2012 16:56:09 +0800 Subject: arm: at91: dt: at91sam9 add serial pinctrl support Set the dbgu pinctrl config by default as we have only one possible config For other uart set the rxd/txd by default. For at91sam9x5ek create soc based dts as we need to include specific soc dtsi.
