[PATCH 0/2] hw/gpio/pca9552: add pca9535 support

Posted by Patrick Williams 2 weeks, 2 days ago

Add support in the PCA9552 model for the PCA9535 and leverage it in
the catalina system model, which has a PCA9535 rather than a PCA9552.

We presently have two PCA95xx chips modelled:
    - PCA9552: A 16-bit LED + GPIO controller.
    - PCA9554: An 8-bit GPIO controller.

PCA9535 is a 16-bit GPIO controller.  I considered creating a new model,
extending PCA9552, or extending PCA9554.  The least code change seemed
to be extending PCA9552 but I could take another approach if desired.
