I spent a bit of time looking at this, but I still do not fully
understand the cause of the hang. It appears to hang initialisation of
the FB subdev and it appears to be around the point where the L2 cache
is flushed. I will see if anyone else has a clue what is happening here.
Ben, in the meantime with the holiday season upon us, should we remove
the bar1 teardown for gk20a?

* [PATCH 43/45] ARM: dts: at91: sama5d2: TC blocks are also simple-mfd and syscon devices
From: Alexandre Belloni @ 2017-12-19 21:32 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171219213209.13823-1-alexandre.belloni@free-electrons.com>
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time and free up the remaining
channels for other use.

The third TC block is missing from the dtsi. It has no output pins but can
still be used for timers as the IRQ is wired.
