* mmc: at91_mci: avoid timeoutsMarc Pignat2008-07-15
| | | | | | | | | | | The at91 mci controller internal state machine seems to often crash. This can be fixed by resetting the controller after each command for at91rm9200 and by setting the MCI_BLKR register on at91sam926*.

* mmc: change .get_ro() callback semanticsAnton Vorontsov2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | Now get_ro() callback must return 0/1 values for its logical states, and negative errno values in case of error. If particular host instance doesn't support RO/WP switch, it should return -ENOSYS. This patch changes some hosts in two ways: 1. Now functions should be smart to not return negative values in "RO asserted" case (particularly gpio_ calls could return negative values for the outermost GPIOs). Also, board code usually passes get_ro() callbacks that directly return gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro() handlers need take special care when returning platform's values to the mmc core. 2. In case of host instance didn't implement get_ro() callback, it should really return -ENOSYS and let the mmc core decide what to do about it (mmc core thinks the same way as the hosts, so it isn't functional change).

* mmc_spi: add support for card-detection pollingAnton Vorontsov2008-07-15
| | | | | | | | | | | | This patch adds new platform data variable "caps", so platforms could pass theirs capabilities into MMC core (for example, platforms without interrupt on the CD line will most probably want to pass MMC_CAP_NEEDS_POLL). New platform get_cd() callback provided to optimize polling. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: add support for card-detection pollingAnton Vorontsov2008-07-15
| | | | | | | | | | | | | Some hosts (and boards that use mmc_spi) do not use interrupts on the CD line, so they can't trigger mmc_detect_change. We want to poll the card and see if there was a change. 1 second poll interval seems resonable. This patch also implements .get_cd() host operation, that could be used by the hosts that are able to report card-detect status without need to talk MMC.

* sdhci: support JMicron secondary interfacePierre Ossman2008-07-15
| | | | | | | JMicron chips sometimes have two interfaces to work around limitations in Microsoft's sdhci driver. This patch allows us to use either interface. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: toggle JMicron PMOS settingPierre Ossman2008-07-15

* sdhci: make workaround for timeout bug more generalPierre Ossman2008-07-15

* sdhci: remove forced dma quirksPierre Ossman2008-07-15
| | | | | | | | Remove the quirk to force DMA on the Ricoh and TI controllers as it is no longer needed. The only bug they have is that they use an incorrect PCI interface value, and that is not respected anymore. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: move pci stuff to separate modulePierre Ossman2008-07-15
| | | | | | | | | | | The SDHCI interface is not PCI specific, yet the Linux driver was intimitely connected to the PCI bus. This patch properly separates the PCI specific portion from the bus independent code. This patch is based on work by Ben Dooks but he did not have time to complete it.

* sdhci: don't check block count for progressPierre Ossman2008-07-15
| | | | | | | | The specification is insufficiently strict when it comes to how the hardware should update the block count register, making it useless for checking transfer progress. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

| | * firmware: Add CONFIG_FIRMWARE_IN_KERNEL option.David Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will control whether we build firmware into the kernel image for _every_ driver which we convert to request_firmware(), to avoid a proliferation of 'CONFIG_XXX_FIRMWARE' options for each one. Default to 'y' for now, which is the wrong thing to do but people seem to be insisting on it and refusing to even review patches until it's done. And it does preserve the existing behaviour for built-in drivers. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

| | * firmware: allow firmware files to be built into kernel imageDavid Woodhouse2008-07-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers have their own hacks to bypass the kernel's firmware loader and build their firmware into the kernel; this renders those unnecessary. Other drivers don't use the firmware loader at all, because they always want the firmware to be available. This allows them to start using the firmware loader. A third set of drivers already use the firmware loader, but can't be used without help from userspace, which sometimes requires an initrd. This allows them to work in a static kernel.
