During testing SoundWire controller on SM8250 MTP, we found
few issues like all the interrupts are not handled,
all transport parameters are not read from device tree.

Other major issue was register read/writes which was interrupt based
was an overhead and puts lot of limitation on context it can be used from.

So this patchset add various improvements to the existing driver
to address above issues.

Tested it on SM8250 MTP with 2x WSA881x speakers, HeadPhones on
WCD938x via lpass-rx-macro and Analog MICs via lpass-tx-macro.
Also tested on DragonBoard DB845c with 2xWSA881x speakers.

Srinivas Kandagatla (6):
  soundwire: qcom: add support to missing transport params
  soundwire: qcom: extract version field
  soundwire: qcom: set continue execution flag for ignored commands
  soundwire: qcom: start the clock during initialization
  soundwire: qcom: update register read/write routine
  soundwire: qcom: add support to new interrupts
