I just wish it was easier to try out git kernels (ones with the prototype patches for video decode) on ARM devices. Having to deal with hacking up device tree files is a bit daunting. It's a good learning experience nonetheless.
It's nice to be able to collect random patches for things and apply them to your kernel and pretty much being good to go on x86. With ARM you have to ensure you instantiated the driver in the device tree file which gets stuck in the boot partition along with the kernel .
