tegra114: add SPI driver

2013-03-25T16:56:07Z

Add driver for tegra114 SPI controller. This controller is not compatible with either the tegra20 or tegra30 controllers, so it requires a new driver. Signed-off-by: Allen Martin Signed-off-by: Tom Warren Reviewed-by: Stephen Warren

spi: add common fdt SPI driver interface

2013-03-25T16:56:06Z

Add a common interface to fdt based SPI drivers. Each driver is represented by a table entry in fdt_spi_drivers[]. If there are multiple SPI drivers in the table, the first driver to return success from spi_init() will be registered as the SPI driver.

tegra: spi: rename tegra SPI drivers

x86: spi: Add Intel ICH driver

2013-03-19T15:45:36Z

This supports Intel ICH7/9. The Intel controller is a little unusual in that it is mostly intended for use with SPI flash, and has some optimisations and features specifically for that application. In particular it is not possible to support ongoing transactions that continue over many calls with SPI_XFER_BEGIN and SPI_XFER_END. This driver supports writes of up to 64 bytes at a time, the limit for the controller. Future work will improve this.

spi: Add function to allocate a new SPI slave

2013-03-19T15:45:36Z

At present it is difficult to extend the SPI structure since all drivers allocate it themselves, and few of them zero all fields. Add a new function spi_alloc_slave() which can be used by SPI drivers to perform this allocation, and thus ensure that all drivers can better cope with SPI structure changes.

blackfin: add bf6xx spi driver

tegra: add SPI SLINK driver

2013-02-11T17:35:25Z

Add driver for tegra SPI "SLINK" style driver. This controller is similar to the tegra20 SPI "SFLASH" controller. The difference is that the SLINK controller is a genernal purpose SPI controller and the SFLASH controller is special purpose and can only talk to FLASH devices. In addition there are potentially many instances of an SLINK controller on tegra and only a single instance of SFLASH. Tegra20 is currently ths only version of tegra that instantiates an SFLASH controller. This driver supports basic PIO mode of operation and is configurable (CONFIG_OF_CONTROL) to be driven off devicetree bindings. Up to 4 devices per controller may be attached, although typically only a single chip select line is exposed from tegra per controller so in reality this is usually limited to 1. To enable this driver, use CONFIG_TEGRA_SLINK Signed-off-by: Allen Martin Signed-off-by: Tom Warren

ColdFire: Queued SPI driver

2012-09-20T12:39:27Z

This patch adds a driver for Freescale Colfire Queued SPI bus. Coded to work with 8 bits per transfer to use with SPI flash. CPOL, CPHA, and CS_ACTIVE_HIGH can be configured. Tested with MCF5270 which have 4 chip selects. Activate by #define CONFIG_CF_QSPI in board config. Signed-off-by: Richard Retanubun
