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.
