* mmc: Fix omap compile by replacing dev_name with dma_dev_nameTony Lindgren2008-05-14
| | | | | | | | | | | | | | | | | | | | This patch fixes error: drivers/mmc/host/omap.c: In function 'mmc_omap_get_dma_channel': drivers/mmc/host/omap.c:1038: error: called object 'dev_name' is not a function Commit 06916639e2fed9ee475efef2747a1b7429f8fe76 adds a function called dev_name. This will cause a name conflict as dev_dbg calls dev_name(((host->mmc)->parent)). This same issue should not affect other drivers as they don't seem to use dev_name with dev_dbg. Thanks to Paul Walmsley <paul@pwsan.com> for figuring this one out. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* MMC: OMAP: Do not busy wait for end of command for everJarkko Lavinen2008-04-18
| | | | | | | | | | | The limit was a fixed 100k limit in the busy loop, which is not accurate. It would better to have time limit for the worst case which occurs when sending 80 cycles at 400 kHz and takes about 200 microseconds, so limit the max time spend in the busy loop for some 250 microseconds.

* MMC: OMAP: Start new commands from work queue instead of irqJarkko Lavinen2008-04-18
| | | | | | | | | Use work queues for starting new commands instead of starting them directly from irq handler. The command scheduling needs to be delayed a bit for some cards which should not be done from an interrupt.

* MMC: OMAP: Lazy clock shutdownJarkko Lavinen2008-04-18
| | | | | | | | | | MMCA spec says the mmc clock should be kept running for at least 8 cycles after the last RW request. Ensure this with lazy clock disable after a request, or with an explicit delay before switching a slot.

* MMC: OMAP: Move failing command abortion to workqueueJarkko Lavinen2008-04-18
| | | | | | | | Abort failed command from workqueue rather than from an interrupt, allowing longer delays in abortion. Signed-off-by: Jarkko Lavinen <jarkko.lavinen@nokia.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* MMC: OMAP: Use tasklet instead of workqueue for cover switch notificationJarkko Lavinen2008-04-18
| | | | | | | | | | | | | The cover waitqueue is occasionally scheduled twice from timer and the interrupt and oops follows. It would have been possible to fix this problem with spinlocks but using tasklet was a dropin solution with no need for locking. This path also adds some cleanups.

* MMC: OMAP: Abort stuck commandsJarkko Lavinen2008-04-18
| | | | | | | | | | | | | | When a card is removed while it is being accessed, a command can get stuck so that no timeout or end of command interrupt ever occurs. The command getting stuck is almost always CDM12, but also the other commands can get stuck. Catch a stuck command with a timer and try sending the initialization stream until the controller starts running again and responds with the end of command status.
