Currently, the channel value for each soundwire port is hardcoded in the wcd937x-sdw driver and the same channel value is configured in the soundwire master. The Qualcomm board like the QCM6490-IDP require static channel map settings for the soundwire master and slave ports. If another boards which are using enable wcd937x, the channel mapping index values between master and slave may be different depending on the board hw design and requirements. If the above properties are not used in a SoC specific device tree, the channel mapping index values are set to default. With the introduction of the following channel mapping properties, it is now possible to configure the master channel mapping directly from the device tree. Added qcom_swrm_set_channel_map api to set the master channel values which allows more flexible to configure channel values in runtime for specific active soundwire ports. Add get and set channel maps support from codec to cpu dais in common Qualcomm sdw driver. Changes since v4: - Update the order of channel map index values in v4-0001 dt-bindings patch as suggested by Krzysztof. Changes since v3: - Change the order of channel map index values in v3-0002 dt-bindings patch as suggested by Krzysztof. - Dropped V3-0001 patch which is not required. Changes since v2: - Rephrase commit description v2-0001 dt-bindings patch as suggested by Krzysztof. Changes since v1: - Modified the design and followed new approach to setting the master channel mask. - Used existing set_channel_map api as suggested by Pierre-Louis - Fixed the typo mistake in v1-0001 dt-bindings patch. - Rephrase the commit description for all v1 patches.
