Only the Layerscape SoCs have interrupts on bus idle, which facilitate sending events which complete slave bus transactions. Add support for synthesizing missing events. If we see a master request, or a newly addressed slave request, if the last event sent to the backend was I2C_SLAVE_READ_REQUESTED, send the backend a I2C_SLAVE_READ_PROCESSED followed by I2C_SLAVE_STOP. For all other events, send an I2C_SLAVE_STOP. Signed-off-by: Kevin Paul Herbert <redacted>
Applied to for-next, thanks!
