Russell,
GPIO support using davinci driver for K2HK/L/E was there for a long time
here: arch/arm/boot/dts/keystone.dtsi
commit 970c225636ac4ae98739094d6b6bbf2bdc3694f9

ARM: dts: keystone: add gpio device entry
I have only added the k2g nodes now as it is different compared to other
keystone 2 platforms.
I believe there is no temperature sensor support for Keystone 2 yet.

Keerthy
