2009-06-14mxcmmc: remove frequency workaroundPierre Ossman1-2/+0
The MMC core has now been fixed to not send silly frequencies to the drivers which means we can remove this workaround. Signed-off-by: Pierre Ossman <pierre@ossman.eu>

2009-06-14mmc: Driver for CB710/720 memory card reader (MMC part)Michał Mirosław4-0/+922
The code is divided in two parts. There is a virtual 'bus' driver that handles PCI device and registers three new devices one per card reader type. The other driver handles SD/MMC part of the reader.

2009-06-14pxamci: add regulator support.Daniel Ribeiro1-5/+41
Changes pxamci.c to use the regulator subsystem. Uses the regulator case CONFIG_REGULATOR is defined and a matching is regulator is provided, or falls back to pdata->setpower otherwise. A warning is displayed case both a valid regulator and pdata is set, and the regulator is used.

2009-06-14sdhci: avoid changing voltage needlesslyPierre Ossman2-26/+29
Because of granularity issues, sometimes we told the hardware to change to the voltage we were already at. Rework the logic so this doesn't happen. Signed-off-by: Pierre Ossman <pierre@ossman.eu>
2009-06-14mmc/omap: make mmci-omap using platform_driver_probeUwe Kleine-König1-2/+1
A pointer to mmc_omap_probe which lives in .init.text is passed to the core via platform_driver_register and so the kernel might oops if probe is called after the init code is discarded. As requested by David Brownell platform_driver_probe is used instead of moving the probe function to .devinit.text. This saves some memory, but might have the downside that a device being registered after the call to mmc_omap_init but before the init sections are discarded will not be bound anymore to the driver.

2009-06-14mmc_spi: speedup for slow cards, less wear-outWolfgang Muees1-0/+12

2009-06-03sdhci-of: Fix the wrong accessor to HOSTVER registerDave Liu1-1/+7
Freescale eSDHC controller has the special order for the HOST version register. that is not same as the other's registers. The address of HOSTVER in spec is 0xFE, and we need use the in_be16(0xFE) to access it, not in_be16(0xFC).

2009-06-03mvsdio: fix config failure with some high speed SDHC cardsNicolas Pitre1-0/+25
Especially with Sandisk SDHC cards, the second SWITCH command was failing with a timeout and the card was not recognized at all. However if the system was busy, or debugging was enabled, or a udelay(100) was inserted before the second SWITCH command in the core code, then the timing was so that the card started to work. With some unusual block sizes, the data FIFO status doesn't indicate a "empty" state right away when the data transfer is done. Queuing another data transfer in that condition results in a transfer timeout. The empty FIFO bit eventually get set by itself in less than 50 usecs when it is not set right away. So let's just poll for that bit before configuring the controller with a new data transfer. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <pierre@ossman.eu>
2009-06-03mvsdio: ignore high speed timing requests from the coreNicolas Pitre1-0/+9
Empirical evidences show that this is causing far more problems than it solves when this mode is enabled in the host hardware. Amongst those cards that are known to be non functional when this bit is set are: A-Data "Speedy" 2GB SD card Kodak 512MB SD card Ativa 1GB MicroSD card Marvell 8688 (WIFI/Bluetooth) SDIO card Since those cards do work on other host controllers which do honnor the hs timing, the issue must be with this particular host hardware.

2009-06-03mmc/omap: Use disable_irq_nosync() from within irq handlers.Ben Nizette1-1/+1
disable_irq() should wait for all running handlers to complete before returning. As such, if it's used to disable an interrupt from that interrupt's handler it will deadlock. This replaces the dangerous instances with the _nosync() variant which doesn't have this problem.

2009-03-24mmc: Add OpenFirmware bindings for SDHCI driverAnton Vorontsov3-0/+321
This patch adds a new driver: sdhci-of. The driver is similar to the sdhci-pci, it contains common probe code, and controller-specific ops and quirks. So far there are only Freescale eSDHC ops and quirks. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2009-03-24sdhci: Add quirk for forcing maximum block size to 2048 bytesAnton Vorontsov2-7/+15
FSL eSDHC controllers can support maximum block size up to 4096 bytes, the MBL (Maximum Block Length) field in the capabilities register extended by one bit, and is set to 0x3. But the SDHCI core doesn't support blocks of 4096 bytes, and thus forces blksz to the lowest value -- 512 bytes. With this patch we can pin up the blksz to the maximum supported block size, i.e. 2048 bytes. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2009-03-24sdhci: Add quirk for controllers that need IRQ re-init after resetAnton Vorontsov2-0/+9

2009-03-24sdhci: Add quirk for controllers that need small delays for PIOAnton Vorontsov2-0/+5
Small udelay is needed to make eSDHC work in PIO mode. Without the delay reading causes endless interrupt storm, and writing corrupts data. The first guess would be that we must wait for some bit in some register, but I didn't find any reliable bits that change before and after the delay.

2009-03-24sdhci: Add set_clock callback and a quirk for nonstandard clocksAnton Vorontsov2-0/+10
FSL eSDHC hosts have incompatible register map to manage the SDCLK. This patch adds set_clock callback so that drivers could overwrite set_clock behaviour. Similar patch[1] was posted by Ben Dooks, though in Ben's version the callback is named change_clock, plus the patch has some unrelated bits that makes the patch difficult to reuse.

2009-03-24sdhci: Add get_{max,timeout}_clock callbacksBen Dooks2-7/+17
Some controllers do not provide clock information in their capabilities (in the Samsung case, it is because there are multiple clock sources available to the controller). Add hooks to allow the system to supply clock information. p.s. In the original Ben's patch there was a bug that makes sdhci_add_host() return -ENODEV even if callbacks were specified.

2009-03-24sdhci: Add support for card-detection pollingAnton Vorontsov2-2/+17
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.

2009-03-24sdhci: Enable only relevant (DMA/PIO) interrupts during transfersAnton Vorontsov1-3/+14
Some hosts (that is, FSL eSDHC) throw PIO interrupts during DMA transfers, this causes tons of unneeded interrupts, and thus highly degraded speed.

2009-03-24sdhci: Split card-detection IRQs management from sdhci_init()Anton Vorontsov2-17/+62
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.

2009-03-24sdhci: Add support for bus-specific IO memory accessorsAnton Vorontsov3-81/+180
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)).
