spi: correct the transfer_one_message documentation wording

2014-01-27T18:45:02Z

The transfer_one_message callback handles messages, not transfers. Signed-off-by: Baruch Siach Signed-off-by: Mark Brown

spi: spi.h: clarify the documentation of transfer_one

2014-01-27T18:43:36Z

Explicitly note the transfer_one and transfer_one_message are mutually exclusive, to make the text a little more newcomers friendly. Signed-off-by: Baruch Siach Signed-off-by: Mark Brown

Pull spi updates from Mark Brown: "A respun version of the merges for the pull request previously sent with a few additional fixes. The last two merges were fixed up by hand since the branches have moved on and currently have the prior merge in them. Quite a busy release for the SPI subsystem, mostly in cleanups big and small scattered through the stack rather than anything else: - New driver for the Broadcom BC63xx HSSPI controller - Fix duplicate device registration for ACPI - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA changes upon which the transiton depends) - Some small optimisations to reduce the amount of time we hold locks in the datapath, eliminate some redundant checks and the size of a spi_transfer - Lots of fixes, cleanups and general enhancements to drivers, especially the rspi and Atmel drivers" * tag 'spi-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (112 commits) spi: core: Fix transfer failure when master->transfer_one returns positive value spi: Correct set_cs() documentation spi: Clarify transfer_one() w.r.t. spi_finalize_current_transfer() spi: Spelling s/finised/finished/ spi: sc18is602: Convert to use bits_per_word_mask spi: Remove duplicate code to set default bits_per_word setting spi/pxa2xx: fix compilation warning when !CONFIG_PM_SLEEP spi: clps711x: Add MODULE_ALIAS to support module auto-loading spi: rspi: Add missing clk_disable() calls in error and cleanup paths spi: rspi: Spelling s/transmition/transmission/ spi: rspi: Add support for specifying CPHA/CPOL spi/pxa2xx: initialize DMA channels to -1 to prevent inadvertent match spi: rspi: Add more QSPI register documentation spi: rspi: Add more RSPI register documentation spi: rspi: Remove dependency on DMAE for SHMOBILE spi/s3c64xx: Correct indentation spi: sh: Use spi_sh_clear_bit() instead of open-coded spi: bitbang: Grammar s/make to make/to make/ spi: sh-hspi: Spelling s/recive/receive/ spi: core: Improve tx/rx_nbits check comments ...

spi: Correct set_cs() documentation

2014-01-21T18:11:49Z

The documentation for spi_master.set_cs() says: assert or deassert chip select, true to assert i.e. its "enable" parameter uses assertion-level logic. This does not match the implementation of spi_set_cs(), which calls spi_master.set_cs() with the wanted logic level of the chip select line, which depends on the polarity of the chip select signal. Correct the documentation to match the implementation. Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

spi: Kill superfluous cast in spi_w8r16()

2014-01-13T11:20:21Z

spi_write_then_read() takes a "void *" for rxbuf, so there's no need to cast the buffer pointer to "u8 *". Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

spi: Use bitfields for multiple data lines

2014-01-13T10:13:28Z

Trent Piepho observed that since the current realistic maximum number of data lines is four we can pack the spi_transfer struct more efficiently if we use a bitfield for the number of bits, allowing the fields to fit in a single byte along with cs_change. If space becomes an issue further optimiation is possible by only using the constants and packing the values chosen for them. Reported-by: Trent Piepho Signed-off-by: Mark Brown
