2021-05-13soundwire: qcom: fix handling of qcom,ports-block-pack-modeSrinivas Kandagatla
Support to "qcom,ports-block-pack-mode" was added at later stages to support a variant of Qualcomm SoundWire controllers available on Apps processor. However the older versions of the SoundWire controller which are embedded in WCD Codecs do not need this property. So returning on error for those cases will break boards like DragonBoard DB845c and Lenovo Yoga C630. This patch fixes error handling on this property considering older usecases.

2021-04-06soundwire: qcom: cleanup internal port config indexingSrinivas Kandagatla
Internally used portconfig array for storing port bandwidth params starts from offset zero. However port zero is not really used and we also copy the bus parameters to offset zero. So basically we endup with a code which has to subtract 1 from port number to get to port parameters. This is bit confusing to the reader so, make this bit more obvious by only copying the parameters to offset 1 instead of zero. This will avoid doing -1 every time when we try to get port params. Similar thing has been recently done with din/dout_port_mask.

2021-03-30soundwire: qcom: update register read/write routineSrinivas Kandagatla
In the existing code every soundwire register read and register write are kinda blocked. Each of these are using a special command id that generates interrupt after it successfully finishes. This is really overhead, limiting and not really necessary unless we are doing something special. We can simply read/write the fifo that should also give exactly what we need! This will also allow to read/write registers in interrupt context, which was not possible with the special command approach. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire This has significantly not only reduced interrupting CPU during enumeration but also during streaming!

2020-05-19soundwire: bus_type: add sdw_master_device supportPierre-Louis Bossart
In the existing SoundWire code, Master Devices are not explicitly represented - only SoundWire Slave Devices are exposed (the use of capital letters follows the SoundWire specification conventions). With the existing code, the bus is handled without using a proper device, and bus->dev typically points to a platform device. The right thing to do as discussed in multiple reviews is use a device for each bus. The sdw_master_device addition is done with minimal internal plumbing and not exposed externally. The existing API based on sdw_bus_master_add() and sdw_bus_master_delete() will deal with the sdw_master_device life cycle, which minimizes changes to existing drivers.
