Subject: [PATCH v2 1/2] ASoC/soundwire: remove is_sdca boolean property

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The Device_ID registers already tell us if a device supports the SDCA
specification or not, in hindsight we never needed a property when the
information is reported by both hardware and ACPI.
