This patch does not build, suggesting it has not been tested. I fixed
it by adding the extra fan nodes that rainier was missing.

How about we support only the latest planar in the mainline tree, and
support for older versions can be carried in the downstream tree?

This has been applied, but without the properties that are not upstream.

These need to be re-worked to use the PCA driver directly instead of
exposing PCA LED devices as GPIO controllers and then attaching
gpio-leds to those GPIOs.

Country to previous concerns raised, there was no issue with "holes"
in the layout but instead a desire to avoid the "pca955x:" prefix in
sysfs. For now userspace will ignore that prefix when matching
devices. I also have a proposed patch to remove them:

The changes I have merged have been pushed here. Please double check
that I've merged what you expected:
