[PATCH v2 0/2] arm64: dts: rockchip: Support PMU for rk3399 SoCs

From: Caesar Wang <hidden>
Date: 2016-07-06 08:06:24

Hello Heiko, Marc & ARM guys

When Jay first submitted the rk3399.dtsi upstream
<https://patchwork.kernel.org/patch/8885821/> he had the PMU node in there,
but then took it out because the upstream binding wasn't done yet.
It looks as if the upstream stuff has landed, since in linux/master I see:
287e9357abcc DT/arm,gic-v3: Documment PPI partition support
e3825ba1af3a irqchip/gic-v3: Add support for partitioned PPIs
9e2c986cb460 irqchip: Add per-cpu interrupt partitioning library
222df54fd8b7 genirq: Allow the affinity of a percpu interrupt to be set/retrieved
651e8b54abde irqdomain: Allow domain matching on irq_fwspec

This series patches add to support the rk3399 SoCs PMU.
I pick up the https://patchwork.kernel.org/patch/9209369/.

As do some tests with ChromeOs for my rk3399 board.
Tested with linus master 4.7-rc6 kernel on rk3399 board.

Changes in v2:
- AS Mark comments on https://patchwork.kernel.org/patch/9209369/
  remove the interrupt-affinity property, we need depend on Marc' perf
  code on https://patchwork.kernel.org/patch/9209369/.

[PATCH v2 2/2] arm64: dts: rockchip: support the pmu node for rk3399

From: Caesar Wang <hidden>
Date: 2016-07-06 08:06:39

This patch add to enable the ARM Performance Monitor Units for rk3399.
ARM cores often have a PMU for counting cpu and cache events like cache
misses and hits.

Also, as the Marc posted the patches [0] to support Partitioning per-cpu
interrupts. Let's add this patch to match it on rk3399 SoCs.

[PATCH v2 1/2] arm64: dts: rockchip: change all interrupts cells for 4 on rk3399 SoCs

From: Caesar Wang <hidden>
Date: 2016-07-06 08:07:10

Add the interrupts cells value for 4, and the 4th cell is zero.

Due to the doc[0] said:" the system requires describing PPI affinity,
then the value must be at least 4"
The 4th cell is a phandle to a node describing a set of CPUs this
interrupt is affine to. The interrupt must be a PPI, and the node
pointed must be a subnode of the "ppi-partitions" subnode. For
interrupt types other than PPI or PPIs that are not partitionned,
this cell must be zero. See the "ppi-partitions" node description
below.

Hi,

These patches themselves look fine, so FWIW:

Acked-by: Mark Rutland <mark.rutland@arm.com>

The prerequisite patch from Marc [1] also largely looks fine, but there
are some minor details to sort out [2], so at this point in time I'm
guesssing this is all v4.9 material.

Thanks,
Mark.

When Jay first submitted the rk3399.dtsi upstream
<https://patchwork.kernel.org/patch/8885821/> he had the PMU node in there,
but then took it out because the upstream binding wasn't done yet.
It looks as if the upstream stuff has landed, since in linux/master I see:
287e9357abcc DT/arm,gic-v3: Documment PPI partition support
e3825ba1af3a irqchip/gic-v3: Add support for partitioned PPIs
9e2c986cb460 irqchip: Add per-cpu interrupt partitioning library
222df54fd8b7 genirq: Allow the affinity of a percpu interrupt to be set/retrieved
651e8b54abde irqdomain: Allow domain matching on irq_fwspec

This series patches add to support the rk3399 SoCs PMU.
I pick up the https://patchwork.kernel.org/patch/9209369/.

As do some tests with ChromeOs for my rk3399 board.
Tested with linus master 4.7-rc6 kernel on rk3399 board.

Heiko,

What do you think of it?
Maybe I need re-update these patches on next kernel, and re-test them.

I checked linux-next and the underlying changes seem to all have gone in now, 
so we should be fine.

Updating the patches would be cool. I tried applying them to my dts64 branch 
just now, but they don't apply cleanly anymore due to other changes going in 
before.

When you check against linux-next, please take into account that there is no 
new linux-next since 20160825 and 20160905 is the next planned linux-next 
release (probably Stephen being on holiday).
