| * mmc: correct request error handlingPierre Ossman2006-12-01
| | | | | | | | | | | | | | | | We need to jump to the part of just flushing the request when we cannot claim the bus. Sending commands to a bus we do not own will give unpredictable results. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * mmc: Flush block queue when removing cardPierre Ossman2006-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | After mmc_block's remove function has exited, we must not touch the card structure in any way. This means we not only must remove the gendisk, we must also flush out any remaning requests already queued up. We previously removed the disk, but didn't flush it, causing oops:es when removing a card in the middle of a transfer. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * mmc: sdhci high speed supportPierre Ossman2006-12-01

| * mmc: Support for high speed SD cardsPierre Ossman2006-12-01
| | | | | | | | | | | | | | | | | | | | | | Modern SD cards support a clock speed of 50 MHz. Make sure we test for this capability and do the song and dance required to activate it. Activating high speed support actually modifies the TRAN_SPEED field of the CSD. But as the spec says that the cards must report 50 MHz, we might as well skip re-reading the CSD.

| * mmc: Fix mmc_delay() functionPierre Ossman2006-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Several fixes for mmc_delay(): * Repair if-clause that was supposed to detect sub-hz delays. * Change yield() to cond_resched() as yield() no longer has the semantics we desire. * mmc_delay() is used to guarantee protocol delays, so we cannot return early (i.e. use _interruptable). Based on patch by Amol Lad. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * mmc: Add support for mmc v4 wide-bus modesPhilip Langdale2006-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds support for the mmc4 4-bit wide-bus mode. The mmc4 spec defines 8-bit and 4-bit transfer modes. As we do not support any 8-bit hardware, this patch only adds support for the 4-bit mode, but it can easily be built upon when the time comes. The 4-bit mode is electrically compatible with SD's 4-bit mode but the procedure for turning it on is different. This patch implements only the essential parts of the procedure as defined by the spec. Two additional steps are recommended but not compulsory. I am documenting them here so that there's a record. 1) A bus-test mechanism is implemented using dedicated mmc commands which allow for testing the functionality of the data bus at the electrical level. This is pretty paranoid and they way the commands work is not compatible with the mmc subsystem (they don't set valid CRC values). 2) MMC v4 cards can indicate they would like to draw more than the default amount of current in wide-bus modes. We currently will never switch the card into a higher draw mode. Supposedly, allowing the card to draw more current will let it perform better, but the specs seem to indicate that the card will function correctly without the mode change. Empirical testing supports this interpretation. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * [PATCH] mmc: Add support for mmc v4 high speed modePhilip Langdale2006-12-01
| | | | | | | | | | | | | | | | | | | | | | | | This adds support for the high-speed modes defined by mmc v4 (assuming the host controller is up to it). On a TI sdhci controller, it improves read speed from 1.3MBps to 2.3MBps. The TI controller can only go up to 24MHz, but everything helps. Another person has taken this basic patch and used it on a Nokia 770 to get a bigger boost because that controller can run at 48MHZ.

When SoftMAC re-enables transmits, it may override the wishes of a driver that may have very good reasons for disabling transmits. At least one failure in bcm43xx can be traced to this problem. In addition, several unexplained problems may arise from the unexpected enabling of transmits. Note that making this change introduces a new bug that would allow transmits for the current session to be transmitted on the wrong channel; however, the new bug is much less severe than the one being fixed, as the new one only leads to a few retransmits, whereas the old one can bring the interface down. A fix that will not introduce new bugs is being investigated; however, the current, more serious one should be fixed now.

The IRQ status bit indicates interface error or protocol mismatch and ahci driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI device raises check condition, ahci interprets it as ATA bus error and thus resets it which, in turn, raises check condition thus creating a reset loop and rendering the device unuseable. This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when interpreting error condition. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Justin Tsai <justin@jmicron.com>
