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] Register the clocks early during the boot process, so that
|
|
special/critical clocks can get enabled early on in the boot process avoiding
|
|
the risk of disabling a clock, pll_divider or pll when a claiming driver
|
|
fails to install propperly - maybe it needs to defer.
