From 45e513b689b8b0a01ec2b01cc21816e4780d7ea6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 15 Jan 2009 18:21:48 +0100 Subject: [PATCH 1/2] ALSA: snd-aoa: handle older machines This patch changes snd-aoa to handle some older machines that are currently handled by snd-powermac. snd-aoa has a number of advantages though, notably it can autoload better and is generally a more modern driver. By hardcoding the accepted device-ids (last hunk of the patch) I'm trying to avoid regressions because this driver will otherwise load automatically and not let snd-powermac load. People who are unhappy with snd-powermac and have a device-id property in the device tree are encouraged to read this patch and make a patch to amend this as appropriate.

This makes snd-aoa handle it, if present in the device tree, thus making snd-aoa be able to output sound on PowerMac3,6, which was previously handled by snd-powermac which also doesn't use the master amp GPIO.
