From 5452030c564686a3dafd355da5456fbeca1de111 Mon Sep 17 00:00:00 2001 From: Ricardo Neri Date: Fri, 18 May 2012 01:42:33 -0500 Subject: ASoC: OMAP: HDMI: Introduce codec Introduce codec for HDMI. At the moment, this is a dummy codec. In the future it will parse the EDID to modify the supported parameters, such as the number of channels and the sample rates. At the moment, it blindly supports all the sample rates and audio channels described in the HDMI 1.4a specification.

We can use 16bit data stream mode if it was valid connection, and it is required for 16bit data DMA transfer / SPDIF sound output. We can use 24bit data transfer if it was invalid connection. We can select connection type if CPU is SH7372, and it is always valid connection if latest SuperH. This patch adds new bus_option and fsi_bus_setup() for supporting these feature.
