Some controllers don't implement these individual operations and have only a transfer method. In that case, we should return an indication that the device is present but doesn't support the method, as opposed to the kobj default error ENXIO which makes it look like the whole device is missing. Userland tools such as i2c(8) can use the differing return values to switch between the two different i2c IO mechanisms. r323553: Defer attaching and probing iicbus and its children until interrupts are available, in i2c controller drivers that require interrupts for transfers. This is the result of auditing all 22 existing drivers that attach iicbus. These drivers were the only ones remaining that require interrupts and were not using config_intrhook to defer attachment. That has led, over the years, to various i2c slave device drivers needing to use config_intrhook themselves rather than performing bus transactions in their probe() and attach() methods, just in case they were attached too early. r323691: Give icee(4) a detach() method so it can be used as a module. Add a module makefile for it. |
