* soundwire: intel: fix implicit header use of module.h/export.hPaul Gortmaker2019-04-142-0/+3
| | | | | | | | | | | | | | | | | | | | | | | These two files are implicitly relying on an instance of including module.h from <linux/acpi.h>. Ideally, header files under include/linux shouldn't be adding includes of other headers, in anticipation of their consumers, but just the headers needed for the header itself to pass parsing with CPP. The module.h is particularly bad in this sense, as it itself does include a whole bunch of other headers, due to the complexity of module support. Here, we make those includes explicit, in order to allow a future removal of module.h from linux/acpi.h without causing build breakage.

* soundwire: Add support to lock across bus instancesSanyog Kale2018-08-272-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the stream concept is limited to single Master and one or more Codecs. This patch extends the concept to support multiple Master(s) sharing the same reference clock and synchronized in the hardware. Modify sdw_stream_runtime to support a list of sdw_master_runtime for the same. The existing reference to a single m_rt is removed in the next patch. Typically to lock, one would acquire a global lock and then lock bus instances. In this case, the caller framework(ASoC DPCM) guarantees that stream operations on a card are always serialized. So, there is no race condition and hence no need for global lock. Bus lock(s) are acquired to reconfigure the bus while the stream is set-up. So, we add sdw_acquire_bus_lock()/sdw_release_bus_lock() APIs which are used only to reconfigure the bus.
