spi-imx: strip down chipselect function to only drive the chipselect

2009-10-01T23:11:17+00:00

spi_imx_chipselect() made things that should be (and mostly are) done by
spi_imx_setupxfer.  Only setting the tx and rx functions was missing.

spi-imx: initialize complete config struct

2009-10-01T23:11:17+00:00

Otherwise the config function uses random data from the stack.  This
didn't stick out because config is called once more in the chipselect
function with correct parameters.

spi-imx: no need to assert bits_per_word being initialized

2009-10-01T23:11:16+00:00

spi_imx_setup() is only called by spi_setup().  The latter does the
initialization already.

spi-imx: fix initial chipselect settings

2009-10-01T23:11:16+00:00

We can only setup the gpio pins in spi_setup time when we know the
SPI_CS_HIGH setting.

spi-imx: rename source file to spi_imx.c

This makes the filename match the Kconfig symbol and the driver name.

spi: handle TX-only/RX-only

2009-09-23T14:39:44+00:00

Support two new half-duplex SPI implementation restrictions, for links
that talk to TX-only or RX-only devices.  (Existing half-duplex flavors
support both transfer directions, just not at the same time.)

Move spi_async() into the spi.c core, and stop inlining it.  Then make
that function perform error checks and reject messages that demand more
than the underlying controller can support.

Based on a patch from Marek Szyprowski which did this only for the
bitbanged GPIO driver.
