From 88359b99d0841d0def5dffff911875dfc78a94fa Mon Sep 17 00:00:00 2001 From: Misael Lopez Cruz Date: Wed, 22 Apr 2015 16:23:00 +0300 Subject: ASoC: omap-hdmi-audio: Force channel allocation only for OMAP4 There is a constraint in the OMAP4 HDMI IP that requires to use the 8-channel code when transmitting more than two channels. The constraint doesn't apply for OMAP5 so don't force the channel allocation in the sound driver as it can be done specifically for OMAP4 later in the hdmi4 core.
