openwrt/target/linux/brcm2708/patches-4.4/0187-BCM270X_DT-Use-spidev-labels-in-overlays.patch
Álvaro Fernández Rojas 2b1c6b21b5 brcm2708: update linux 4.4 patches to latest version 
As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.4.y

Also adds support for Raspberry Pi Compute Module 3 (untested).
