From c840fc745f6ec8a3b7062d72de193ab9c397d725 Mon Sep 17 00:00:00 2001 From: Michael Williamson Date: Tue, 18 Jan 2011 12:21:44 -0500 Subject: davinci: da850: move da850_evm specific mcasp pins to board file. The da850_mcasp_pins pinmux array is specific to the da850_evm, and is not generic. Move the array to the board file, make it static initdata, and rename it accordingly.
