eef1276565 configs/stm32f103-minimum: Remove nonsensical #error. 2018-01-09 11:17:01 -06:00

1182702b80 drivers/ioexpander: The IRQ subsystem now supports passing a void * parameter to IRQ handlers. Use that method to support multiple pc9555 devices, by passing a pointer to the device to the board defined irq handler. Now the CONFIG_ for multiple PCA devices just allocates device structures dynamically instead of statically when not enabled. 
The same interrupt handler is entered with the device structure parameter in all situations,
multiple or single PCA. One should still be careful if multiple PCA devices share the same IRQ.

5f9ee79298 I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h definitons. Add support for an attach() method that may be used when any subset of pin interrupts occur. 
PCA9555 Driver:  Replace the signalling logic with a simple callback using the new definitons of ioexpander.h.  This repartitioning of functionality is necessary because (1) the I/O expander driver is the lower-lower part of any driver that uses GPIOs (include the GPIO driver itself) and should not be interacting directly with the much higher level application layer.  And (2) in order to be compatible with the GPIO driver (and any arbitrary upper half driver), the PCA9555 should not directly signal, but should call back into the upper half.  The upper half driver that interacts directly with the application is the appropriate place to be generating signal.
