From c4e1662550a3bd23df7cff4611eff67ba2afe078 Mon Sep 17 00:00:00 2001 From: Boojin Kim Date: Fri, 2 Sep 2011 09:44:35 +0900 Subject: ARM: SAMSUNG: Add common DMA operations This patch adds common DMA operations which are used for Samsung DMA drivers. Currently there are two types of DMA driver for Samsung SoCs. The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs. This patch provides funcion pointers for common DMA operations to DMA client driver like SPI and Audio. It makes DMA client drivers support multi-platform. In addition, this common DMA operations implement the shared actions that are needed for DMA client driver. For example shared actions are filter() function for dma_request_channel() and parameter passing for device_prep_slave_sg().

Samsung sound driver uses DMA generic API if architecture supports it. Otherwise, use samsung specific S3C-PL330 API driver to transfer PCM data.

Basically the samsung_xxx prefix is used in gpio-samsung.c instead of s3c_xxx, because unified name can reduce its complexity. Note: some s3c_xxx stil remains because it is used widely. It will be updated next time.
