spi: Add designware master SPI DM driver used on SoCFPGA

2014-12-06T12:52:47Z

This patch adds the driver for the Designware master SPI controller. This IP core is integrated on the Altera SoCFPGA. This implementation is a driver model (DM) implementation. So multiple SPI drivers can be used. Thats necessary, since SoCFPGA also integrates the Cadence QSPI controller used to connect the SPI NOR flashes. Without DM, using multiple SPI drivers is not possible. This driver is very loosely based on the Linux driver. Most of the Linux driver is removed. Only the polling loop for the transfer is really used from this driver, as we don't support interrupts and DMA right now. This is tested on the SoCrates SoCFPGA board using the SPI pins on the P14 header.

spi: Add Cadence QSPI DM driver used by SoCFPGA

2014-12-06T12:52:46Z

This driver is cloned from the Altera Rockerboard.org U-Boot repository. I used this git tag: ACDS14.0.1_REL_GSRD_RC2. With Some modification to support the U-Boot driver model (DM). As mentioned above, in this new version I ported this driver to the new driver model (DM). One big advantage of this move is that now multiple SPI drivers can be enabled on one platform. And since the SoCFPGA also has the Designware SPI master controller integrated, this feature is really needed to support both controllers. Because of this, this series needs the DT support for SoCFPGA to be applied. For DT based probing in the SPI DM.

dm: tegra: spi: Convert to driver model

2014-10-22T16:36:52Z

This converts the Tegra SPI drivers to use driver model. This is tested on: - Tegra20 - trimslice - Tegra30 - beaver - Tegra124 - dalmore (not tested on Tegra124) Reviewed-by: Jagannadha Sutradharudu Teki Signed-off-by: Simon Glass

dm: spi: Add soft_spi implementation

2014-10-22T16:36:48Z

Add a new implementation of soft_spi that uses device tree to specify the GPIOs. This will replace soft_spi_legacy for boards which use driver model. Signed-off-by: Simon Glass Reviewed-by: Jagannadha Sutradharudu Teki

dm: spi: Rename soft_spi.c to soft_spi_legacy.c

2014-10-22T16:36:48Z

Reserve the 'normal' name for use by driver model, and rename the old driver so that it is clear that it is for 'legacy' drivers only. Signed-off-by: Simon Glass Reviewed-by: Jagannadha Sutradharudu Teki

dm: sandbox: Add a SPI emulation uclass

2014-10-22T16:36:46Z

U-Boot includes a SPI emulation driver already but it is not explicit, and is hidden in the SPI flash code. Conceptually with sandbox's SPI implementation we have a layer which creates SPI bus transitions and a layer which interprets them, currently only for SPI flash. The latter is actually an emulation, and it should be possible to add more than one emulation - not just SPI flash. Add a SPI emulation uclass so that other emulations can be plugged in to support different types of emulated devices on difference buses/chip selects.

dm: spi: Add a uclass for SPI

2014-10-22T16:36:46Z

Add a uclass which provides access to SPI buses and includes operations required by SPI. For a time driver model will need to co-exist with the legacy SPI interface so some parts of the header file are changed depending on which is in use. The exports are adjusted also since some functions are not available with driver model. Boards must define CONFIG_DM_SPI to use driver model for SPI.
