We need the char/misc driver fixes in here as well. Signed-off-by: Greg Kroah-Hartman

soundwire: intel: fix PDI/stream mapping for Bulk

2019-11-09T11:14:44Z

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: cadence_master: make clock stop exit configurable on init

2019-10-24T11:52:01Z

The use of clock stop is not a requirement, the IP can e.g. be completely power gated and not detect any wakes while in s2idle/deep sleep. For now clock-stop is not supported anyways so the control parameter is always false. This will be revisited when we add clock stop.

soundwire: intel/cadence: add flag for interrupt enable

soundwire: intel/cadence: fix startup sequence

2019-10-24T11:52:01Z

Multiple changes squashed in single patch to avoid tick-tock effect and avoid breaking compilation/bisect 1. Per the hardware documentation, all changes to MCP_CONFIG, MCP_CONTROL, MCP_CMDCTRL and MCP_PHYCTRL need to be validated with a self-clearing write to MCP_CONFIG_UPDATE. Add a helper and do the update when the CONFIG is changed. 2. Move interrupt enable after interrupt handler registration 3. Add a new helper to start the hardware bus reset with maximum duration to make sure the Slave(s) correctly detect the reset pattern and to ensure electrical conflicts can be resolved. 4. flush command FIFOs Better error handling will be provided after interrupt disable is provided in follow-up patches.

soundwire: intel: fix intel_register_dai PDI offsets and numbers

2019-10-21T04:21:02Z

There are two issues, likely copy/paste: 1. Use cdns->pcm.num_in instead of stream_num_in for consistency with the rest of the code. This was not detected earlier since platforms did not have input-only PDIs. 2. use the correct offset for bi-dir PDM, based on IN and OUT PDIs. Again this was not detected since PDM was not supported earlier.

soundwire: cadence_master: improve PDI allocation

PDI number should match dai->id, there is no need to track if a PDI is allocated or not. Signed-off-by: Bard Liao Signed-off-by: Pierre-Louis Bossart Link: https://lore.kernel.org/r/20190916192348.467-7-pierre-louis.bossart@linux.intel.com Signed-off-by: Vinod Koul

soundwire: cadence/intel: simplify PDI/port mapping

2019-10-21T04:20:53Z

The existing Linux code uses a 1:1 mapping between ports and PDIs, but still has an independent allocation of ports and PDIs. Let's simplify the code and remove the port layer by only using PDIs. This patch does not change any functionality, just removes unnecessary code. This will also allow for further simplifications where the PDIs are not dynamically allocated but instead described in a topology file.
