* pxamci: fix byte aligned DMA transfersPhilipp Zabel2008-07-06
| | | | | | | | | | | | | | | The pxa27x DMA controller defaults to 64-bit alignment. This caused the SCR reads to fail (and, depending on card type, error out) when card->raw_scr was not aligned on a 8-byte boundary. For performance reasons all scatter-gather addresses passed to pxamci_request should be aligned on 8-byte boundaries, but if this can't be guaranteed, byte aligned DMA transfers in the have to be enabled in the controller to get correct behaviour.

* mmc: don't use DMA on newer ENE controllersPierre Ossman2008-07-04
| | | | | | | | | | | | Even the newer ENE controllers have bugs in their DMA engine that make it too dangerous to use. Disable it until someone has figured out under which conditions it corrupts data. This has caused problems at least once, and can be found as bug report 10925 in the kernel bugzilla.

* olpc: sdhci: add quirk for the Marvell CaFe's interrupt timeoutAndres Salomon2008-07-04
| | | | | | | | | | | | | | | | | | | | | | The CaFe chip has a hardware bug that ends up with us getting a timeout value that's too small, causing the following sorts of problems: [ 60.525138] mmcblk0: error -110 transferring data [ 60.531477] end_request: I/O error, dev mmcblk0, sector 1484353 [ 60.533371] Buffer I/O error on device mmcblk0p2, logical block 181632 [ 60.533371] lost page write due to I/O error on mmcblk0p2 Presumably this is an off-by-one error in the hardware. Incrementing the timeout count value that we stuff into the TIMEOUT_CONTROL register gets us a value that works. This bug was originally discovered by Pierre Ossman, I believe.

* olpc: sdhci: add quirk for the Marvell CaFe's vdd/powerup issueAndres Salomon2008-07-04
| | | | | | | | | | | | | | | | This has been sitting around unloved for way too long.. The Marvell CaFe chip's SD implementation chokes during card insertion if one attempts to set the voltage and power up in the same SDHCI_POWER_CONTROL register write. This adds a quirk that does that particular dance in two steps. It also adds an entry to pci_ids.h for the CaFe chip's SD device.

* | [ARM] 5024/1: Fix some minor clk issues in the MMCI PL18x driverLinus Walleij2008-05-04
|/ | | | | | | | | | | | | This fixes some two minor clk issues. The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing. The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem. This is not applied on top of the earlier mmci patch for race condition but rather a clean 2.6.25, but I guess it applies without major protests anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updated version of 4446/1. This also drops the suggested comparison of host_remain for == 0, since that doesn't make sense (still works for us, too). We have verified that this patch solve race problems on atleast 2 archs at high frequencies. (Verbatim copy of old patch text below.) The patch below fixes a race condition in the ARM MMCI PL18x driver. If new data arrives in the FIFO while existing data is being read then we get a second iteration of the loop in mmci_pio_read. However host->size is not updated until after mmci_pio_read returns, so we get count = number of new bytes PLUS number of bytes already copied in the first iteration. This results in a FIFO underrun as we try and read mode data than is available. The fix is to compensating for data read on previous iterations when calculating the amount of data in the FIFO.

Also that code uses use dev_*() for messaging, and has less abuse of KERN_ERR. Likewise with updating remove() cleanup. This had to free the GPIOs, and while adding that code I noticed and fixed two other problems: it was poking at a workqueue owned by the mmc core; and in one (rare) case would try freeing an IRQ that it didn't allocate.
