From a98d90e7d588045716c3c85d63f93dc3f15a079b Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 20 Feb 2018 14:19:33 +0200 Subject: gpio: raspberrypi-exp: Driver for RPi3 GPIO expander via mailbox service Pi3 and Compute Module 3 have a GPIO expander that the VPU communicates with. There is a mailbox service that now allows control of this expander, so add a kernel driver that can make use of it.
