soundwire: intel: fix PDI/stream mapping for Bulk

2019-12-31T15:35:55+00:00

[ Upstream commit c134f914e9f55b7817e2bae625ec0e5f1379f7cd ] The previous formula is incorrect for PDI0/1, the mapping is not linear but has a discontinuity between PDI1 and PDI2. This change has no effect on PCM PDIs (same mapping).

soundwire: intel: fix channel number reported by hardware

2019-10-07T16:57:11+00:00

[ Upstream commit 18046335643de6d21327f5ae034c8fb8463f6715 ] On all released Intel controllers (CNL/CML/ICL), PDI2 reports an invalid count, force the correct hardware-supported value This may have to be revisited with platform-specific values if the hardware changes, but for now this is good enough.

soundwire: Remove cdns_master_ops

2018-05-11T16:18:05+00:00

There can be instances where drivers using Cadence IP might want to set sdw_master_ops differently per instance of it's use, so remove the cdns_master_ops and export the APIs. Signed-off-by: Shreyas NC Signed-off-by: Vinod Koul

soundwire: intel: fix missing assignment to ret

2018-01-08T16:53:21+00:00

Currently the return status ret is being checked but it has not been updated since the previous check on ret. It appears that assignment of ret from return status of the call to sdw_cdns_enable_interrupt was accidentally ommited. Fix this.
