Probe/remove functions need to be marked as __devinit and __devexit (not __init an __exit) to prevent trying to run code that has been discarded. This patch fixes the spi_imx driver to mark probe and remove correctly. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

This change adds the OMAP SPI 100k driver created by Fabrice Crohas <fcrohas@gmail.com>. This SPI bus is found on OMAP7xx-series smartphones, and for many, the touchscreen is attached to this bus. The lion's share of the work was done by Fabrice on this driver -- I am merely porting it from the Linwizard project on his behalf.

This patch is V2 of SPI Master support for the SuperH MSIOF. Full duplex, spi mode 0-3, active high cs, 3-wire and lsb first should all be supported, but the driver has so far only been tested with "mmc_spi". The MSIOF hardware comes with 32-bit FIFOs for receive and transmit, and this driver simply breaks the SPI messages into FIFO-sized chunks. The MSIOF hardware manages the pins for clock, receive and transmit (sck/miso/mosi), but the chip select pin is managed by software and must be configured as a regular GPIO pin by the board code. Performance wise there is still room for improvement, but on a Ecovec board with the built-in sh7724 MSIOF0 this driver gets Mini-sd read speeds of about half a megabyte per second. Future work include better clock setup and merging of 8-bit transfers into 32-bit words to reduce interrupt load and improve throughput.

i.MX35-provided chipselects are represented using negative numbers. If gpio_request() fails and the previous chipselect was a negative number, the while loop is endless (i is never decremented). Also, the error loop would never call gpio_free on chipselect[0]. And finally, the error message was missing an endline.

On the MX31litekit, the bootloader seems to communicate with the MC13783 PMIC chip before booting Linux. However, it does not flush all the buffers properly after that, which makes the imx-spi driver read bogus data when probing the MC13783. Fix that by draining the SPI receive buffer on startup.

This patch adds in support for the DS570 IP. It's register compatible with the DS464, but adds support for 8/16/32 SPI. The 8/16/32 support is added by attaching callbacks reading/writing the proper amount of data. To indicate to the driver which amount of bits to use a new field is introduced in the platform data struct.

This one enables the mpc52xx_spi driver for usage of user defined gpio lines as chipselect. This way we can control some more spi devices than only one V2 Changes: * preinitialize the gpio as output in probe function and call gpio_set_value in the chip select function instead of calling direction_output every time. * initialize the gpio line with output high, since we don't support CS_HIGH in the driver currently any way. change gpio value setting to default active low in chip select call. * free the gpio array while error or removing.

Before reading status register to check MODF failure, we have to clear it first since the MODF flag will be set after initializing the spi master, if the hardware comes up with a low SS. The processor datasheet reads: Mode Fault flag -- bit sets if SS input goes low while SPI is configured as a master. Flag is cleared automatically by an SPI status register read (with MODF set) followed by a SPI control register 1 write. Hence simply rereading the register is not sufficient to clear the flag. We redo the write also to make sure to clear the flag.
