cleanup asm/scatterlist.h includes

2007-11-02T07:47:06Z

Not architecture specific code should not #include . This patch therefore either replaces them with #include or simply removes them if they were unused. Signed-off-by: Adrian Bunk Signed-off-by: Jens Axboe

mmc: use common byte swap macros

2007-10-27T12:41:04Z

Use the more generic byte swapping macros instead of the socket variants. Signed-off-by: Pierre Ossman

MMC core learns about SPI

2007-09-23T19:51:30Z

Teach the MMC/SD/SDIO core about using SPI mode. - Use mmc_host_is_spi() so enumeration works through SPI signaling and protocols, not just the native versions. - Provide the SPI response type flags with each request issued, including requests from the new lock/unlock code. - Understand that cmd->resp[0] and mmc_get_status() results for SPI return different values than for "native" MMC/SD protocol; this affects resetting, checking card lock status, and some others. - Understand that some commands act a bit differently ... notably: * OP_COND command doesn't return the OCR * APP_CMD status doesn't have an R1_APP_CMD analogue Those changes required some new and updated primitives: - Provide utilities to access two SPI-only requests, and one request that wasn't previously needed: * mmc_spi_read_ocr() ... SPI only * mmc_spi_set_crc() ... SPI only (override by module parm) * mmc_send_cid() ... for use without broadcast mode - Updated internal routines: * Previous mmc_send_csd() modified into mmc_send_cxd_native(); it uses native "R2" responses, which include 16 bytes of data. * Previous mmc_send_ext_csd() becomes new mmc_send_cxd_data() helper for command-and-data access * Bugfix to that mmc_send_cxd_data() code: dma-to-stack is unsafe/nonportable, so kmalloc a bounce buffer instead. - Modified mmc_send_ext_csd() now uses mmc_send_cxd_data() helper - Modified mmc_send_csd(), and new mmc_spi_send_cid(), routines use those helper routines based on whether they're native or SPI The newest categories of cards supported by the MMC stack aren't expected to work yet with SPI: MMC or SD cards with over 4GB data, and SDIO. All those cards support SPI mode, so eventually they should work too. Signed-off-by: David Brownell Signed-off-by: Pierre Ossman

mmc: mmc_set_data_timeout() parameter write is redundant

2007-09-23T07:15:00Z

The write parameter in mmc_set_data_timeout() is redundant as the data structure contains information about the direction of the transfer. Signed-off-by: Pierre Ossman

mmc: remove custom error codes

2007-09-23T06:46:48Z

Convert the MMC layer to use standard error codes and not its own, incompatible values. Signed-off-by: Pierre Ossman

drivers/mmc/core/: make 3 functions static

2007-07-26T00:05:57Z

This patch makes the following needlessly global functions static: - sd_ops.c: mmc_app_cmd() - core.c: __mmc_release_bus() - core.c: mmc_start_request() Signed-off-by: Adrian Bunk Signed-off-by: Pierre Ossman

mmc: update header file paths

2007-07-25T23:53:31Z

Make sure all headers in the files reflect their true position in the tree. Signed-off-by: Pierre Ossman

mmc: Separate out protocol ops

2007-05-01T11:04:18Z

Move protocol operations and definitions into their own files in an effort to separate protocol handling and bus arbitration more clearly. Signed-off-by: Pierre Ossman
