* sdhci: support for ADMA only hostsRichard Röjfors2009-09-231-1/+1
| | | | | | | | | | | Add support for ADMA on SDHCI hosts, not supporting SDMA. According to the SDHCI specifications a host can support ADMA but not SDMA Signed-off-by: Richard Röjfors <richard.rojfors@mocean-labs.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | Card insertion detection is broken without this quirk on a Sony Vaio Z11, as discussed on linux-mmc here: http://marc.info/?t=125017355000008 Signed-off-by: Chris Ball <cjb@laptop.org> Tested-by: Norbert Preining <preining@logic.at> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* sdhci: Specific quirk vor VIA SDHCI controller in VX855ESHarald Welte2009-06-211-0/+20
| | | | | | | | | | The SDHCI controller found in the VX855ES requires 10ms delay between applying power and applying clock. This issue has been discovered and documented by the OLPC XO1.5 team. Signed-off-by: Harald Welte <HaraldWelte@viatech.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>
* sdhci-pci: bad error handling in probe functionDan Carpenter2009-05-031-3/+5
| | | | | | | | | | | | The goto unmap is too early, we haven't allocated host or done the request_region(). Found by smatch (http://repo.or.cz/w/smatch.git). [ Second error path fix by Pierre Ossman ] Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>

* sdhci: Add NO_BUSY_IRQ quirk for Marvell CAFE host chipAndres Salomon2009-03-021-0/+1
| | | | | | | | | | | As described here: http://lkml.org/lkml/2009/2/20/265 The CAFE chip is broken due to commit e809517f6fa5803a5a1cd5602. Anton added a quirk here: http://lkml.org/lkml/2009/2/20/279 that fixes CAFE's problem. This adds the quirk for CAFE.

* Revert "sdhci: force high speed capability on some controllers"Pierre Ossman2009-02-181-2/+1
| | | | | | | | | | This reverts commit a4b76193774b463b922cab2f92450efb20d29ef0. It turned out that the controller had problem running at the higher speed, so go back to trusting the hardware capability bits. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* pci: use pci_ioremap_bar() in drivers/mmcArjan van de Ven2008-12-311-1/+1
| | | | | | | | | | Use the new pci_ioremap_bar() function in drivers/mmc. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

| * sdhci: force high speed capability on some controllersPierre Ossman2008-10-121-1/+2
| | | | | | | | | | | | | | Some high speed capable controllers forget to set the high speed capability bit. Make sure we enable the functionality anyway. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

* sdhci: scatter-gather (ADMA) supportPierre Ossman2008-07-151-0/+17
| | | | | | | | | | | Add support for the scatter-gather DMA mode present on newer controllers. As the mode requires 32-bit alignment, non-aligned chunks are handled by using a bounce buffer. Also add some new quirks to handle controllers that have bugs in the ADMA engine. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci-pci: don't penalize newer jmicron chipsPierre Ossman2008-07-151-4/+6
| | | | | | | The upcoming JMicron chips will have solved all the currently known bugs, so don't penalize them for older problems. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci-pci: unaligned data with ricoh controllersPierre Ossman2008-07-151-0/+1
| | | | | | The Ricoh controllers cannot handle unaligned data blocks. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: handle hot-removePierre Ossman2008-07-151-5/+16
| | | | | | | Gracefully handle when the device is suddenly removed. Do a test read and avoid any further access if that read returns -1. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: support JMicron secondary interfacePierre Ossman2008-07-151-2/+125
| | | | | | | 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 Ossman2008-07-151-0/+67
| | | | | | | | Some of the JMicron chips requires us to manually enable the power output stages of the chip. Add the necessary hooks and functions to manage this. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: make workaround for timeout bug more generalPierre Ossman2008-07-151-1/+1
| | | | | | | | Give the quirk for broken timeout handling a better chance of handling more controllers by simply classifying the system as broken and setting a fixed value. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: more complex quirks handlingPierre Ossman2008-07-151-43/+86
| | | | | | | Extend the quirks handling in the PCI driver to be able to have callbacks and not just flags. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
* sdhci: remove forced dma quirksPierre Ossman2008-07-151-20/+2
| | | | | | | | 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 Ossman2008-07-151-0/+486
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>
