From 773b1d3d31bbf7257c48f6257b4ab06bcf4f5dfa Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 12 Apr 2011 11:40:39 -0600 Subject: ASoC: Tegra: Support more boards * Ventana is identical to Harmony. * Seaboard, Kaen, and Aebl are all pretty similar, mainly with slightly different sets of GPIOs, and slightly different WM8903 pin connectivity.
