From fce21ae4ccfcee0c28fb18f5507e145fb0b02dec Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 22 Mar 2017 21:09:00 +0100 Subject: brcm2708: rename all patches from raspberrypi git tree to use 950 prefix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
