From: Conor Dooley <conor.doo...@microchip.com> Here's a U-Boot implementation of the changes I'm trying to make in https://lore.kernel.org/all/20241002-private-unequal-33cfa6101338@spud/ that affect how the clocks are described in devicetree for PolarFire SoC. There's been no complaints about the only part that impacts U-Boot, so I figured it was time to send patches here.
I've implemented things here in a backwards compatible manner, so that these changes can be applied now without the relevant devicetree patches (since the dust has not settled on all aspects of the rework) and the revised devicetree can make its way into U-Boot via a regular OF_UPSTREAM update once merged "upstream". ~There's minor duplication with Hal's work in patch 3, but I think that's~ ~not particularly important, given it is the addition of a trivial~ ~Makefile we both require:~ ~https://lore.kernel.org/all/20240930155919.111738-1-hal.f...@starfivetech.com~ In v2, I rebased on top of master as Sumit suggested to pick up the movement of some dts Makefile, so while there's still a bit of duplication, what's here is "better" than what's linked above. Cheers, Conor.
