This patchset combines three contributions:
Srinivas Kandagalta suggested creating a device even it's detected on the bus but not described in platform firmware. I suggested adding the device number and status to show the difference with 'ghost' devices, described in firmware but not physically present. Vinod suggested a simpler way to report the status.
I did not keep Vinod's patch separate since it was using the same group attribute as the other properties, which prevents status and device number from being reported if there is no firmware and no driver.
These patches were tested on Qualcomm and Intel platforms.
v2: as suggested by GregKH, add attribute group by default by setting the groups pointer at the device level.
Pierre-Louis Bossart (1): soundwire: sysfs: add slave status and device number before probe
Srinivas Kandagatla (1): soundwire: bus: add enumerated Slave device to device list
