| * spi/mpc8xxx: don't use __exit_p to wrap plat_mpc8xxx_spi_removeUwe Kleine-König2009-12-081-1/+1
| | | | | | | | | | | | | | | | The function plat_mpc8xxx_spi_remove is defined using __devexit, so don't use __exit_p but __devexit_p to wrap it. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* | powerpc: Fix build of some FSL platformsBenjamin Herrenschmidt2009-11-241-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 87ec0e98cfdd8b68da6a7f9e70142ffc0e404fbb in kumar's next branch broke one of my test configs since it looks like Anton forgot about that mpc832x_rdb platform which still uses the old style probing for the SPI stuff. I'll let them do a cleaner fix that probably involves changing the probing method and getting rid of the platform device but for now this will do to fix it.

* | spi_mpc8xxx: Add support for QE DMA mode and CPM1/CPM2 chipsAnton Vorontsov2009-11-111-40/+500
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds QE buffer descriptors mode support for the spi_mpc8xxx driver, and as a side effect we now support CPM1 and CPM2 SPI controllers. That means that today we support almost all MPC SPI controllers: - MPC834x-style controllers (support PIO mode only); - CPM1 and CPM2 controllers (support DMA mode only); - QE SPI controllers in CPU mode (PIO mode with shift quirks); - QE SPI controllers in buffer descriptors (DMA) mode; The only controller we don't currently support is a newer eSPI (with a dedicated chip selects and a bit different registers map).

* | spi_mpc8xxx: Turn qe_mode into flagsAnton Vorontsov2009-11-111-11/+19
| | | | | | | | | | | | | | | | | | | | | | Soon there will be more flags introduced in subsequent patches, so let's turn qe_mode into flags. Also introduce mpc8xxx_spi_strmode() and print current SPI mode.

* spi_mpc8xxx: s/83xx/8xxx/gAnton Vorontsov2009-06-191-200/+200
| | | | | | | | | | | | | | Since we renamed the file, we might want to rename the file internals too. Though we don't bother with changing platform driver name and platform module alias. The stuff is legacy and hopefully we'll remove it soon.

* spi_mpc83xx: rename spi_83xx.c to spi_8xxx.cAnton Vorontsov2009-06-191-0/+945
The driver handles MPC83xx, MPC85xx and MPC86xx SPI controllers, so rename the file for clarity.
