spi: add spi_tegra driver
v2 changes:
from Thierry Reding:
* add "select TEGRA_SYSTEM_DMA" to Kconfig
from Grant Likely:
* add oneline description to header
* inline references to DRIVER_NAME
* inline references to BUSY_TIMEOUT
* open coded bytes_per_word()
* spi_readl/writel -> spi_tegra_readl/writel
* move transfer validation to spi_tegra_transfer
* don't request_mem_region iomem as platform bus does that for us
* __exit -> __devexit
v3 changes:
from Russell King:
* put request_mem_region back int
from Grant Likely:
* remove #undef DEBUG
* add SLINK_ to register bit defines
* remove unused bytes_per_word
* make spi_tegra_readl/writel static linine
* various refactoring for clarity
* mark err if BSY bit is not cleared after 1000 retries
* move spinlock to protect setting of RDY bit
* subsys_initcall -> module_init
v3 changes:
from Grant Likely:
* update spi_tegra to use PTR_ERRless dma API
v4 changes:
from Grant Likely:
* remove empty spi_tegra_cleanup fucntion
* allow device ids of -1
