* au1xmmc: remove custom carddetect poll implementation.Manuel Lauss2008-07-15
| | | | | | | | The MMC core provides a carddetect poll feature, time to remove the driver's own implementation of it. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* au1xmmc: remove db1200 board code, rewrite probe.Manuel Lauss2008-07-15
| | | | | | | | | | | | | | Remove the DB1200 board-specific functions (card present, read-only, activity LED methods) and instead add platform data which is passed to the driver. This also allows for platforms to implement other carddetect schemes (e.g. dedicated irq) without having to pollute the driver code. The poll timer (used for pb1200) is kept for compatibility. With the board-specific stuff gone, the driver's ->probe() code can be cleaned up considerably.

* at91_mci: Fix byte mode transitions.Ville Syrjala2008-07-15
| | | | | | | | | | The byte mode support fails to clear the byte mode bit in the command register, possibly leaving byte mode enabled with the counters programmed in non-byte mode.

* at91_mci: Cover more AT91RM9200 and AT91SAM9261 errata.Ville Syrjala2008-07-15
| | | | | | | | | | | According to the documentation the AT91SAM9261 MCI shares the block size limitations of the AT91RM9200 MCI. Also the errata documentation for AT91RM9200 and AT91SAM9261 state that stream commands are not supported. This has not been tested on actual hardware.

* at91_mci: AT91SAM9260/9263 12 byte write erratum (v2)Ville Syrjala2008-07-15
| | | | | | | | | | AT91SAM926[0/3] PDC must write at least 12 bytes. The code compiles and runs but the actual condition for this erratum did not trigger in my tests so it's unclear if it actually works as intended.

* at91_mci: manage cmd error and data error independentlyNicolas Ferre2008-07-15
| | | | | | | | | In at91_mci_completed_command() function, this patch distinguishes command error and data error. It reports it in the corresponding error field. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* mmc: at91_mci: do not read irq status twice as it will forget some errorsNicolas Ferre2008-07-15
| | | | | | | | Reading AT91_MCI_SR again at the end of transfer can corrupt the error reporting. Some fields in the SR register are read-and-clear. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* mmc: at91_mci: update bytes_xfered value once xfer doneNicolas Ferre2008-07-15
| | | | | | | | | | | | | Modify bytes_xfered value after a write. That will report, as accurately as possible, the amount of sectors that are effectively written. This update introduces the check of the busy signal given by the card. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* 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

* 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. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* 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: Correct dependency on CONFIG_EXTRA_FIRMWARE_DIRDavid Woodhouse2008-07-14
| | | | | | | | | | | When CONFIG_EXTRA_FIRMWARE_DIR gets changed, the filename in the .S file (which uses .incbin to include the binary) needs to change. When we renamed the BUILTIN_FIRMWARE_DIR option to EXTRA_FIRMWARE_DIR, we forgot to update the manual dependency in firmware/Makefile, so it was depending on a non-existent file in include/config/ Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
