| * sdhci: Add support for card-detection pollingAnton Vorontsov2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vorontsov2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | 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 Vorontsov2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Vorontsov2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)).

| * omap_hsmmc: Fix response type for busy after responseAdrian Hunter2009-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMC commands result in the card becoming busy after the response is received. 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>
