-Subject: [yocto][meta-raspberrypi][PATCH v4 4/5] linux-raspberrypi_4.4.inc:
- support for .dtbo files for dtb overlays
-
-Upstream-Status: Pending
-
-Kernel 4.4.6+ on RaspberryPi support .dtbo files for overlays, instead of .dtb.
-Patch the kernel, which has faulty rules to generate .dtbo the way yocto does
