| * spi/xilinx: Fix compile errorGrant Likely2010-05-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | 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: move bitbang txrx utility functions to private headerhartleys2010-05-257-111/+98

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 <linux/spi/spi_bitbang.h> 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.

| * | powerpc/mpc5121: move PSC FIFO memory init to platform codeAnatolij Gustschin2010-05-252-69/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since PSC could also be used in other modes than UART mode we move PSC FIFO memory initialization from serial driver to common platform code. The initialized FIFO memory slices may not overlap, so the most easy way would be to configure them all at once at init time for all PSC devices. This is now done by this patch.

| * | spi/omap2_mcspi: add turbo mode supportRoman Tereshonkov2010-05-251-21/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When one regulator supplies another allow the relationship to be specified using names rather than struct regulators, in a similar manner to that allowed for consumer supplies. This allows static configuration at compile time, reducing the need for dynamic init code. Also change the references to LINE supply to be system supply since line is sometimes used for actual supplies and therefore potentially confusing.

Also the timeout values in the module description and error message were clarified. And the _STS registers are 16 bit instead of 8 bit.

Some are simple as add a parenthesis. Others are problems from __stringify() being used on a variable name instead of a macro name, so the variable name is produced in the string instead of its build-time value. In these cases, create a macro for the value so that the module param description string is useful. Only pc87413_wdt has been built (due to toolchains).
