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 Likely1-3/+8
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 Likely1-75/+2
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 Likely1-2/+3
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>

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 Brownell1-0/+9
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.
