Back in July, Qualcomm submitted a patch that added this information
into the device tree:
http://marc.info/?t=137185166100003&r=1&w=2
However, this was rejected. Now it appears that this information is
again being added to the device tree, but it's being accepted. What's
different now?
Another problem is that these device tree changes makes it difficult to
support ACPI. It's easy to move information between the drivers and the
device tree, because they're kept together. It's not so easy with ACPI.
I'm trying to add ACPI support to the 8x74 pinctrl driver, but it's a
moving target.
