2010-05-27mmc: s3c6410: add new quirk in sdhci driver and update ADMA descriptor buildThomas Abraham2-5/+17
The s3c6410 sdhci controller does not support the 'End' attribute and NOP attribute in the same 8-Byte ADMA descriptor. This patch adds a new quirk to identify sdhci host contollers with such behaviour. In addition to this, for controllers using the new quirk, the last entry in the ADMA descritor table is marked with the 'End' attribute (instead of using a NOP descriptor with 'End' attribute).

2010-05-27sdhci: build fix: rename SDHCI I/O accessor functionsMatt Fleming3-30/+30
Unfortunately some architectures #define their read{b,w,l} and write{b,w,l} I/O accessors which makes the SDHCI I/O accessor functions of the same names subject to preprocessing. This leads to the following compiler error, In file included from drivers/mmc/host/sdhci.c:26: drivers/mmc/host/sdhci.h:318:35: error: macro "writel" passed 3 arguments, but takes just 2 Rename the SDHCI I/O functions so that CONFIG_MMC_SDHCI_IO_ACCESSORS can be enabled for architectures that implement their read{b,w,l} and write{b,w,l} functions with macros.

2010-05-27mmc: atmel-mci: Add support for SDIO interruptsAnders Grahn1-4/+38
Atmel-mci support for SDIO interrupts. This adds the enable_sdio_irq() function and the configuration of sdio irq mask per slot. With this irq mask information, we keep the idea of multiple slot per sd/mmc host (not only A and B). MMC_CAP_SDIO_IRQ is added according to slot configuration. A new little function is added to run mmc_signal_sdio_irq() during interrupt handling routine.

2010-05-27mmc-omap: add support for 16-bit and 32-bit registersMarek Belisko1-29/+33
The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring a modification of the register addresses in the mmc-omap driver. To resolve this, a bit shift is performed on base register addresses, either by 1 or 2 bits depending on the CPU in use. This yields the correct registers for each CPU.

2010-05-27davinci: mmc: pass number of SG segments as platform dataSudhakar Rajashekhara2-7/+20
On some platforms like DM355, the number of EDMA parameter slots available for EDMA_SLOT_ANY usage are few. In such cases, if MMC/SD uses 16 slots for each instance of MMC controller, then the number of slots available for other modules will be very few. By passing the number of EDMA slots to be used in MMC driver from platform data, EDMA slots available for other purposes can be controlled. Most of the platforms will not use this platform data variable. But on DM355, as the number of EDMA resources available is limited, the number of scatter- gather segments used inside the MMC driver can be 8 (passed as platform data) instead of 16. On DM355, when the number of scatter-gather segments was reduced to 8, I saw a performance difference of about 0.25-0.4 Mbytes/sec during write. Read performance variations were negligible.

2010-05-26Input: ads7846 - return error on regulator_get() failureKevin Hilman1-2/+2
In probe(), if regulator_get() failed, an error code was not being returned causing the driver to be successfully bound, even though probe failed. This in turn caused the suspend, resume and remove methods to be registered and accessed via the SPI core. Since these functions all access private driver data using pointers that had been freed during the failed probe, this would lead to unpredictable behavior. This patch ensures that probe() returns an error code in this failure case so the driver is not bound. Found using lockdep and noticing the lock used in the suspend/resum path pointed to a bogus lock due to the freed memory.
