2010-02-27MMC: AU1xMMC: Allow platforms to disable host capabilitiesManuel Lauss1-0/+4
Although the hardware supports a 4/8bit SD interface and the driver unconditionally advertises all hardware caps to the MMC core, not all datalines may actually be wired up. This patch introduces another field to au1xmmc platform data allowing platforms to disable certain advanced host controller features.

2010-02-27MIPS: Alchemy: change dbdma to accept physical memory addressesManuel Lauss1-2/+2
DMA can only be done from physical addresses; move the "virt_to_phys" source/destination buffer address translation from the dbdma queueing functions (since the hardware can only DMA to/from physical addresses) to their respective users.

2010-02-27MIPS: Alchemy: remove dbdma compat macrosManuel Lauss1-2/+2
Remove dbdma compat macros, move remaining users over to default queueing functions and -flags. (Queueing function signature has changed in order to give a build failure instead of silent functional changes due to the no longer implicitly specified DDMA_FLAGS_IE flag) Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-08-01au1xmmc: raise segment size limit.Manuel Lauss1-1/+7
Raise the DMA block size limit from 2048 bytes to the maximum supported by the DMA controllers on the chip (64KB on Au1100, 4MB on Au1200). This gives a very small performance boost and apparently fixes an oops when MMC-DMA and network traffic are active at the same time.

2008-07-23au1xmmc: suspend/resume implementationManuel Lauss1-12/+42
Basic suspend/resume support: disable peripheral on suspend and reinit on resume. Tested on Au1200. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15au1xmmc: remove custom carddetect poll implementation.Manuel Lauss1-61/+18
The MMC core provides a carddetect poll feature, time to remove the driver's own implementation of it. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15au1xmmc: abort requests early if no card is present.Manuel Lauss1-0/+7
Don't process an MMC request if no card is present. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15au1xmmc: codingstyle tidying.Manuel Lauss1-92/+141

2008-07-15au1xmmc: remove db1200 board code, rewrite probe.Manuel Lauss1-233/+340
Remove the DB1200 board-specific functions (card present, read-only, activity LED methods) and instead add platform data which is passed to the driver. This also allows for platforms to implement other carddetect schemes (e.g. dedicated irq) without having to pollute the driver code. The poll timer (used for pb1200) is kept for compatibility. With the board-specific stuff gone, the driver's ->probe() code can be cleaned up considerably.

2008-04-16mmc: fix platform driver hotplug/coldplugKay Sievers1-0/+2
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable MMC host platform drivers, to re-enable auto loading. Also, add missing owner declarations in driver init.
