| | | | | | | | | | SD/MMC card timeouts can be very high. So avoid busy-waiting, using the scheduler. Calculate all timeouts in jiffies units, because this will give us the correct sign when to involve the scheduler.

* mmc_spi: do not check CID and CSD blocks with CRC16Wolfgang Muees2009-04-081-9/+12
| | | | | | | | | | | | Some cards are not able to calculate a valid CRC16 value for CID and CSD reads (CRC for 512 byte data blocks is OK). By moving the CRC enable after the read of CID and CSD, these cards can be used. This patch was tested with a faulty 8 GByte takeMS Class 6 SDHC card. This patch was suggested by Pierre Ossman.

| | | | | | | | | | | | | | | Spurious IRQs seen on MMC after 2.6.29. Flush posted write in IRQ handler. The interrupt line is released by clearing the error status bits in the MMCHS_STAT register, which must occur before the interrupt handler returns to avoid unwanted irqs. Hence the need to flush the posted write.

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new driver: sdhci-of. The driver is similar to the sdhci-pci, it contains common probe code, and controller-specific ops and quirks.

| * sdhci: Add quirk for forcing maximum block size to 2048 bytesAnton Vorontsov2009-03-242-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | FSL eSDHC controllers can support maximum block size up to 4096 bytes, the MBL (Maximum Block Length) field in the capabilities register extended by one bit, and is set to 0x3. But the SDHCI core doesn't support blocks of 4096 bytes, and thus forces blksz to the lowest value -- 512 bytes. With this patch we can pin up the blksz to the maximum supported block size, i.e. 2048 bytes. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

| * sdhci: Add quirk for controllers that need small delays for PIOAnton Vorontsov2009-03-242-0/+5
| | | | | | | | | | | | | | | | | | | | | | Small udelay is needed to make eSDHC work in PIO mode. Without the delay reading causes endless interrupt storm, and writing corrupts data. The first guess would be that we must wait for some bit in some register, but I didn't find any reliable bits that change before and after the delay.

| * sdhci: Add set_clock callback and a quirk for nonstandard clocksAnton Vorontsov2009-03-242-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FSL eSDHC hosts have incompatible register map to manage the SDCLK. This patch adds set_clock callback so that drivers could overwrite set_clock behaviour. Similar patch[1] was posted by Ben Dooks, though in Ben's version the callback is named change_clock, plus the patch has some unrelated bits that makes the patch difficult to reuse.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some controllers do not provide clock information in their capabilities (in the Samsung case, it is because there are multiple clock sources available to the controller). Add hooks to allow the system to supply clock information. p.s. In the original Ben's patch there was a bug that makes sdhci_add_host() return -ENODEV even if callbacks were specified.

| | | | | | | | | | | | | | | | | | | | | | This patch adds SDHCI_QUIRK_INVERTED_WRITE_PROTECT quirk. When specified, the sdhci driver will invert WP state. p.s. Actually, the quirk is more board-specific than controller-specific. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
| * sdhci: Add support for card-detection pollingAnton Vorontsov2009-03-242-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds SDHCI_QUIRK_BROKEN_CARD_DETECTION quirk. When specified, sdhci driver will set MMC_CAP_NEEDS_POLL MMC host capability, and won't enable card insert/remove interrupts. This is needed for hosts with unreliable card detection, such as FSL eSDHC. The original eSDHC driver was tring to "debounce" card-detection IRQs by reading present state and disabling particular interrupts. But with this debouncing scheme I noticed that sometimes we miss card insertion/removal events.

| * sdhci: Enable only relevant (DMA/PIO) interrupts during transfersAnton Vorontsov2009-03-241-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | Some hosts (that is, FSL eSDHC) throw PIO interrupts during DMA transfers, this causes tons of unneeded interrupts, and thus highly degraded speed. This patch modifies the driver so that now we only enable relevant (DMA or PIO) interrupts during transfers.

| * sdhci: Split card-detection IRQs management from sdhci_init()Anton Vorontsov2009-03-242-17/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Card detection interrupts should be handled separately as they should not be enabled before mmc_add_host() returns and should be disabled before calling mmc_remove_host(). The same is for suspend and resume routines. sdhci_init() no longer enables card-detection irqs. Instead, two new functions implemented: sdhci_enable_card_detection() and sdhci_disable_card_detection(). New sdhci_reinit() call implemented to behave the same way as the old sdhci_init(). Also, this patch implements and uses few new helpers to manage IRQs in a more conveinient way, that is: - sdhci_clear_set_irqs() - sdhci_unmask_irqs() - sdhci_mask_irqs() - SDHCI_INT_ALL_MASK constant sdhci_enable_sdio_irq() converted to these new helpers, plus the helpers will be used by the subsequent patches.

| * sdhci: Add support for bus-specific IO memory accessorsAnton Vorontsov2009-03-243-81/+180
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the SDHCI driver works with PCI accessors (write{l,b,w} and read{l,b,w}). With this patch drivers may change memory accessors, so that we can support hosts with "weird" IO memory access requirments. For example, in "FSL eSDHC" SDHCI hardware all registers are 32 bit width, with big-endian addressing. That is, readb(0x2f) should turn into readb(0x2c), and readw(0x2c) should be translated to le16_to_cpu(readw(0x2e)).

This needs to be specified for the omap_hsmmc host controller, which is what this patch does. However, the effect is that some commands with no data will cause a Transfer Complete (TC) interrupt in addition to the Command Complete (CC) interrupt. In order to deal with that, the irq handler has needed a few changes also. The benefit of this change is that the omap_hsmmc host controller driver now waits for the TC interrupt while the card is busy, so the mmc_block driver needs to poll the card status just once instead of repeatedly. i.e. the net result is more sleep and less cpu. The command sequence for open-ended multi-block write with DMA is now: Issue write command CMD25 Receive CC interrupt Data is sent Receive TC interrupt (DMA is done) Issue stop command CMD12 Receive CC interrupt Card is busy Receive TC interrupt Card is now ready for next transfer Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
