Recent DTS update brought in switch to the new PMC clock
bindings, however we do not support that yet. Revert this
change until PMC clock bindings support is implemented.
Fixes: 33fdc89d4cbd ("dts: update to v5.0-rc1")

dts/ contains a 1:1 copy from the upstream devicetree-rebasing
repository. I can't apply any patches to this directory.
You would have to merge the changes to the changes to the corresponding
files in arch/arm/dts. I'm not sure how feasible this is in this case
since not only the clock nodes are changed, but also the references to
the clocks.
For sure it should be enough to fix the trees you actually can test and
care about.

My board is not upstreamed as it does not make sense to do it so. It will
never hit the market. Also upstream barebox does not use DT on any
at91sam9g20 SoC, so it is safe. However there seem to be devices using
AT91SAM9X5, SAMA5D3 and SAM9263 which depends on DT clocks and those
are now broken. That said, I can live with one more offtree patch until
new PMC clock binding is implemented (reverting change in arch/arm/dts
is a bit painfull).
On the other hand, was the DT update to v5.0-rc1 and later to v5.0-rc2
motivated by any need or it is just an update to be in sync? If that
is the latter I'd just revert it for barebox-2019.02.0 :)
Best regards,
ladis

The breakage was anticipated for my part, no suprise.
I just do not have time to look into it at the moment.
The objective for my part is to have all at91 boards moved over to DT,
so we will have to face this.
Or in other words patching all DT files in arch/arm/dts is
not IMO a feasible long term solution.
I got a new at91sam9gxx board from Microchip two weeks ago,
and that is my next DT target.
Then I hope we can maybe mass convert the rest of the
at91 baords with some limited testing.
But this clock issue will need to be fixed first.
Sam

I have now ported the clk code from the kernel so barebox
have support for PMC bindings.
Can you give it a try and see if this works for you.
So far I have only tested this on at91sam9263ek - a DT enabled board.
It builds for non-DT boards.
Patch needs a bit love before it is ready to submit.
Could I get early feedback that would be great.

Subject: [PATCH v1 1/1] clk: at91: update to new bindings
Based on kernel 5.0-rc6 update at91 clk support
to match the new PMC bindings.
This add new drivers:
at91sam9260, at91sam9rl, at91sam9x5, sama5d2 and sama5d4
They were copied from the kernel and saw minimal modifications
required to build under barebox.
For the remaining files the updates in the kernel from last
kernel copy was identified and similar changes were made
in the files in barebox.
The kernel has a dt-compat file for all the backward
compatibility code.
As barebox has only a few DT enabled at91 targets this was not ported
over.
clk-programmable saw some extra changes - it had never been bulit.
It is used only by at91sama5d2 - and barebox has no baord support for
this cpu at the moment.
To match the kernel the CONFIG symbols used to select individual
files were updated and there are now specific CONFIG symbols
for SAMA5D2, SAM5D3 and SAMA5D4
In the kernel CLK_OF_DECLARE_DRIVER() can be used for a two step init.
In barebox this is a simple one step init.
It was added to have less differences between the kernel and the barebox
versions of the drivers.
