mmc: Move atmel_mci driver into drivers/mmc

2008-07-09T22:05:52+00:00

This makes it easier to use the driver on other platforms.

avr32: Use CONFIG_ATMEL_MCI to select the atmel_mci driver

2008-07-09T22:04:47+00:00

After we move the atmel_mci driver into drivers/mmc, we can't select
it with CONFIG_MMC anymore. Introduce a new symbol specifically for
this driver so that there's no ambiguity.

MMC: Consolidate MMC/SD command definitions

2008-06-28T20:40:15+00:00

This moves the MMC and SD Card command definitions from
include/asm/arch/mmc.h into include/mmc.h. These definitions are
given by the MMC and SD Card standards, not by any particular
architecture.

There's a lot more room for consolidation in the MMC drivers which
I'm hoping to get done eventually, but this patch is a start.

Compile-tested for all avr32 boards as well as lpc2292sodimm and
lubbock. This should cover all three mmc drivers in the tree.

avr32: Fix SPI portmux initialization

2008-06-20T10:46:43+00:00

Use the new GPIO manipulation functions to set up the chip select lines,
and make sure both busses use GPIO for chip select control.

atmel_spi: Driver for the Atmel SPI controller

2008-06-03T18:30:05+00:00

This adds a driver for the SPI controller found on most AT91 and AVR32
chips, implementing the new SPI API.

Changed in v4:
  - Update to new API
  - Handle zero-length transfers appropriately. The user may send a
    zero-length SPI transfer with SPI_XFER_END set in order to
    deactivate the chip select after a series of transfers with chip
    select active. This is useful e.g. when polling the status
    register of DataFlash.

avr32: Fix theoretical race in udelay()

2008-05-27T13:27:31+00:00

If the specified delay is very short, the cycle counter may go past the
"end" time we are waiting for before we get around to reading it.

Fix it by checking the different between the cycle count "now" and the
cycle count at the beginning. This will work as long as the delay
measured in number of cycles is below 2^31.

avr32: Compile atmel_mci.o conditionally

2008-05-27T13:27:31+00:00

Remove #ifdef CONFIG_MMC from the source file and use conditional
compilation in the Makefile instead.

avr32: Fix wrong error flags in atmel_mci driver

2008-05-27T13:27:31+00:00

Make sure we check for CRC errors when sending commands that use CRC
checking.
