spi: expose master transfer size limitation.

2016-01-05T16:33:54+00:00

On some SPI controllers it is not feasible to transfer arbitrary amount of data at once. When the limit on transfer size is a few kilobytes at least it makes sense to use the SPI hardware rather than reverting to gpio driver. The protocol drivers need a way to check that they do not sent overly long messages, though. Signed-off-by: Michal Suchanek Signed-off-by: Mark Brown

spi: add spi_message_init_no_memset to avoid zeroing the spi_message

2015-12-12T23:05:18+00:00

In the spi_loopback_test driver there is the need to initialize a spi_message that is filled with values from a static structure. Applying spi_message_init to such a prefilled structure results in all the settings getting reset to zero, which is not what we want. Copying each field of spi_message separately instead always includes the risk that some new fields have not been implemented in the copying code. So here we introduce a version of spi_message_init called spi_message_init_no_memset that does not fill the structure with zero first, but only initializes the relevant list_heads.

spi: Add THIS_MODULE to spi_driver in SPI core

2015-10-28T01:30:12+00:00

Add spi_register_driver helper macro that adds THIS_MODULE to spi_driver for the registering driver. We rename and modify the existing spi_register_driver to enable this. Signed-off-by: Andrew F. Davis Signed-off-by: Mark Brown

spi: fix kernel-doc warnings about missing return desc in spi.h

2015-10-23T16:28:35+00:00

When building docs with make htmldocs, warnings about not having a description for the return value are reported, i.e: warning: No description found for return value of 'spi_write' Fix these by following the kernel-doc conventions explained in Documentation/kernel-doc-nano-HOWTO.txt.
