2008-04-11spi: fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable SPI platform drivers, to allow module auto loading.

2008-03-04powerpc: mpc5200: fix build error on mpc52xx_psc_spi device driverGrant Likely
Commit id 94f389485e27641348c1951ab8d65157122a8939 (Separate MPC52xx PSC FIOF regsiters from the rest of PSC) split the PSC fifo registers away from the core PSC regs. Doing so broke the mpc52xx_psc_spi driver. This patch teaches the mpc52xx_psc_spi driver about the new PSC fifo register definitions.

2008-01-26[POWERPC] mpc52xx_psc_spi device driver must not touch port_config and cdmGrant Likely
It is dangerous for an mpc52xx device driver to modify the port_config register. If the driver is probed incorrectly, it will change the pin IO configuration in ways which may not be compatible with the board. port_config should be set up by the bootloader, or failing that, in the platform setup code in arch/powerpc/platforms/52xx. Also, modifying CDM registers directly can cause a race condition with other drivers. Instead call a common routine to modify CDM settings.

2008-01-26[POWERPC] mpc5200: normalize compatible property bindingsGrant Likely
Update MPC5200 drivers to also look for compatible properties in the form "fsl,mpc5200-*" to better conform to open firmware generic names recommended practice as published here: http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html This patch should *not* break compatibility with older device trees which do not use the 'fsl,' prefix. The drivers will still bind against the older names also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2008-01-18[POWERPC] mpc5200: eliminate mpc52xx_*_map_*() functions.Grant Likely
mpc5200 platform code defines a bunch of map functions which duplicate the functionality of of_iomap(). Remove them and use of_iomap() instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

2007-07-17SPI controller drivers: check for unsupported modesDavid Brownell
Minor SPI controller driver updates: make the setup() methods reject spi->mode bits they don't support, by masking aginst the inverse of bits they *do* support. This insures against misbehavior later when new mode bits get added. Most controllers can't support SPI_LSB_FIRST; more handle SPI_CS_HIGH. Support for all four SPI clock/transfer modes is routine.

Fix mpc5200 PSC SPI driver to actually work for CONFIG_PPC_MERGE - s/mpc52xx/mpc5200/, as this was changed in device tree some time ago - fix spi id detection The move from 'ppc' to 'powerpc' didn't quite match the latest kernel.org code.
