Merge tag 'bcm2835-dt-next-2018-02-28' into devicetree/next
This pull request adds automatic BT probing to the Pi Zero W, OTG mode for the Zero W, the GPIO expander on the Pi3, and fixes I2S probe (which is disabled by default, but often used downstream) Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
