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. Patch to add Auto Enumeration supported by the controller is also part of this series. 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. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire 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. Changes since v3: - Fixed setting assigned bit during autoenumeration Srinivas Kandagatla (9): dt-bindings: soundwire: qcom: clarify data port bus parameters soundwire: qcom: add support to missing transport params 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 soundwire: export sdw_compare_devid() and sdw_extract_slave_id() soundwire: qcom: add auto enumeration support soundwire: qcom: wait for enumeration to be complete in probe .../bindings/soundwire/qcom,sdw.txt | 20 + drivers/soundwire/bus.c | 4 +- drivers/soundwire/qcom.c | 529 ++++++++++++++---- include/linux/soundwire/sdw.h | 2 + 4 files changed, 442 insertions(+), 113 deletions(-)
