openwrt/target/linux/brcm2708/patches-4.9/950-0143-BCM270x-DT-Consolidate-audio-card-overlays.patch
Rafał Miłecki fce21ae4cc brcm2708: rename all patches from raspberrypi git tree to use 950 prefix 
Right now all brcm2708 patches are extracted from the non-mainline
raspberrypi/linux git tree. Many of them are hacks and/or are unneeded
in LEDE. Raspberry Pi is getting better and better mainline support so
it would be nice to finally start maintaining patches in a cleaner way:
1) Backport patches accepted in upstream tree
2) Start using upstream drivers
3) Pick only these patches that are needed for more complete support

Handling above tasks requires grouping patches - ideally using the same
prefixes as generic ones. It means we should rename existing patches to
use some high prefix. This will allow e.g. use 0xx for backported code.

Subject: [PATCH] BCM270x DT: Consolidate audio card overlays
Reference 3.3V / 5V system rails instead of instantiating local
regulators.
Add missing power supply properties for codecs where these are
required according to the DT bindings docs.
