From 9dcaa7b25f2c8f6a0485854cd3641f585a154072 Mon Sep 17 00:00:00 2001 From: Rafael Ignacio Zurita Date: Tue, 3 Nov 2009 17:16:27 -0300 Subject: ALSA: sh: add SuperH DAC audio driver for ALSA V4 This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx). Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed.
