spi: bitbang: Make spi_bitbang_stop() return void

2014-03-29T11:09:26Z

spi_bitbang_stop() never fails, so make it return void. Signed-off-by: Axel Lin Signed-off-by: Mark Brown

spi/bitbang: Use core message pump

2013-07-17T17:13:01Z

Convert drivers using bitbang to use the core mesasge pump infrastructure, saving some code and meaning that these drivers get to take advantage of work done on improving the core implementation. Signed-off-by: Mark Brown

spi/bitbang: Unexport spi_bitbang_transfer()

2013-07-15T10:29:52Z

Currently no drivers use the ability to override spi_bitbang_transfer() and if any started this would make it harder to convert the bitbang code to use transfer_one_message() so remove the export in order to prevent anyone starting. Signed-off-by: Mark Brown

spi: move bitbang txrx utility functions to private header

2010-05-25T06:23:17Z

A number of files in drivers/spi fail checkincludes.pl due to the double include of . The first include is needed to get the struct spi_bitbang definition and the spi_bitbang_* function prototypes. The second include happens after defining EXPAND_BITBANG_TXRX to get the inlined bitbang_txrx_* utility functions. The header is also included by a number of other spi drivers, as well as some arch/ code, in order to use struct spi_bitbang and the associated functions. To fix the double include, and remove any potential confusion about it, move the inlined bitbang_txrx_* functions to a new private header in drivers/spi and also remove the need to define EXPAND_BITBANG_TXRX.

tree-wide: fix typos "selct" + "slect" -> "select"

SPI controller drivers: check for unsupported modes

2007-07-17T17:23:04Z

Minor SPI controller driver updates: make the setup() methods reject spi->mode bits they don't support, by masking aginst the inverse of bits they *do* support. This insures against misbehavior later when new mode bits get added. Most controllers can't support SPI_LSB_FIRST; more handle SPI_CS_HIGH. Support for all four SPI clock/transfer modes is routine.

[PATCH] spi: destroy workqueue after spi_unregister_master

2007-03-17T02:25:04Z

Fix a bug in the cleanup of an spi_bitbang bus. The workqueue associated with the bus was destroyed before the call to spi_unregister_master. That meant that spi devices on that bus would be unable to do IO in their remove method. The shutdown flag should have been able to prevent a segfault, but was never getting set. By waiting to destroy the workqueue until after the master is unregistered, devices are able to do IO in their remove methods. An added benefit is that neither the shutdown flag nor a wait for the queue of messages to empty is needed.

[PATCH] SPI cleanup() method param becomes non-const

2007-02-12T17:48:31Z

I'd like to assign NULL to kfree()d members of a structure. I can't do that without ugly casting (see the PXA patch) when the structure pointed to is const-qualified. I don't really see a reason why the cleanup method isn't allowed to alter the object it should clean up. :-) No, I didn't test the PXA patch, but I verified that the NULL-assignment doesn't stop me from doing rmmod/insmodding my own spi_bitbang-based driver.
