Changes in v3: * Fix the MAINTAINERS file. * Fix the bindings (clocks description, size-cells, etc) * Add Rob's Ack on one patch. * Dropped unnecessary locks. * Used a hardware feature to automatically NACK IBI's during regular data transfers. * Stopped flushing FIFOs (not needed). * Entirely reworked the IBI handling logic. * Dropped the warning when a device does not advertise it's dynamic address during an IBI. * Moved the IBI logic into the master's workqueue instead of a threaded handler. * Added a svc_i3c_master_readb() helper. * Used consistent bit definitions (BIT() vs. FIELD_GET()). Changes in v2: * Change the manufacturer name from svc to silvaco.
