Wed Sep 8 07:06:38 EDT 2010
This patch updates Audio and SPI for S5P6440 and S5P6450 SoCs.
Signed-off-by: Kukjin Kim <kgene.kim at samsung.com>
Cc: Jassi Brar <jassi.brar at samsung.com>
---
Changes since v2:
- Merged platform_device for spi
Changes since v1:
- Fix mis-name s3c64x0-xxx
- Fix mis-name S5P6440_SPI_SRCCLK
- Build tested with modifying Makefile for test
- Merged s5p6440_spi_set_info and s5p6450_xxx to one function
