2018-03-28	stm class: Make dummy's master/channel ranges configurable	Alexander Shishkin
	To allow for more flexible testing of the stm class, make it possible to specify the ranges of masters and channels that the dummy_stm devices cover. This is done via module parameters. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>
2018-03-28	stm class: Add SPDX GPL-2.0 header to replace GPLv2 boilerplate	Alexander Shishkin
	This adds SPDX GPL-2.0 header to to stm core files and removes the GPLv2 boilerplate text. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>
2016-11-22	stm dummy: Mark dummy_stm_packet() with notrace	Chunyan Zhang
	If CONFIG_STM_SOURCE_FTRACE is selected, Function trace data can be writen to sink via STM, all functions that related to writing data packets to STM should be marked 'notrace' to avoid being traced by Ftrace, otherwise the program would stall into an endless loop.

2016-04-08	stm class: dummy_stm: Make nr_dummies parameter read-only	Alexander Shishkin
	Changing nr_dummies after the module has been loaded doesn't actually change anything, so just make it read-only. Reported-by: Alan Cox <alan.cox@intel.com> Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com> Reviewed-by: Laurent Fert <laurent.fert@intel.com>
2016-02-20	stm class: dummy_stm: Add link callback for fault injection	Alexander Shishkin
	STM device's link callback has the power to abort master/channel assignment by returning a negative error code. Use this in dummy stm device to optionally abort assigning certain channel IDs. This is useful as fault injection into the stm class core, for testing purposes.

2016-02-20	stm class: dummy_stm: Create multiple devices	Alexander Shishkin
	STM framework should be able to handle multiple STM devices at a time, each one with its own master allocation policy. This patch changes dummy_stm driver to create multiple STM sinks to help testing the framework.

2015-10-04	stm class: dummy_stm: Add dummy driver for testing stm class	Alexander Shishkin
	This is a simple module that pretends to be an stm device and discards all the data that comes in. Useful for testing stm class and its users.
