of/spi: Fix build failure on spi_ppc4xx.c

2010-06-02T19:38:33+00:00

This patch fixes a build error caused by the OF device_node pointer
being moved into struct device.

Fixes bug introduced by commit 61c7a080a5a061c976988fd4b844dfb468dda255
(of: Always use 'struct device.of_node' to get device node pointer)

spi/xilinx: Fix compile error

2010-05-25T06:48:24+00:00

Commit 58f9b0b02414062eaff46716bc04b47d7e79add5, "of: eliminate
of_device->node and dev_archdata->{of,prom}_node" changed the location
of the device_node pointer.  Most drivers were converted to the new
location, but the xilinx_spi_of driver was missed and now fails to
compile.

This patch fixes up the xilinx_spi_of driver to use the new location.

spi/davinci: Fix clock prescale factor computation

2010-05-25T06:23:54+00:00

Computation of the clock prescaler value returned bogus results if
the requested SPI clock was impossible to set. It now sets either
the maximum or minimum clock frequency, as appropriate.

spi: move bitbang txrx utility functions to private header

2010-05-25T06:23:17+00:00

A number of files in drivers/spi fail checkincludes.pl due to the double
include of .

The first include is needed to get the struct spi_bitbang definition and
the spi_bitbang_* function prototypes.

The second include happens after defining EXPAND_BITBANG_TXRX to get the
inlined bitbang_txrx_* utility functions.

The  header is also included by a number of other
spi drivers, as well as some arch/ code, in order to use struct spi_bitbang
and the associated functions.

To fix the double include, and remove any potential confusion about it, move
the inlined bitbang_txrx_* functions to a new private header in drivers/spi
and also remove the need to define EXPAND_BITBANG_TXRX.

spi/omap2_mcspi: add turbo mode support

2010-05-25T06:23:15+00:00

Turbo mode allows to read data to shift register when rx-buffer
is full thus improving the perfomance. This feature is available
for RX-only mode.

In PIO turbo mode when the penultimate word is available
in RX-buffer the controller should be disabled before reading data
to prevent the next transaction triggering. The controller itself
handles the last word to be correctly loaded to shift-register and
then transferred to RX-buffer.

The turbo mode is enabled by setting turbo_mode parameter to 1.
This parameter is a part of omap2_mcspi_device_config structure
which is passed through the spi_device controller_data pointer.
