[PATCHv2 0/5] arm: specify PMU type in platform data

[PATCHv2 0/5] arm: specify PMU type in platform data

[Mark Rutland]

Currently the ARMv6, ARMv7, and XScale PMU drivers are coupled with each
other, and all included in the same c file. To enable the splitting of
the ARMv6, ARMv7, and XScale PMU drivers, and the conversion of the
arm_pmu framework to a pure library, we need to be a be more precise
when describing PMUs, to enable association of the PMU with the right
driver. In device tree this is already implicit in the compatible
string, but platform data currently only specifies "arm-pmu".

Commit 253d8c3d2518ca6f (arm: perf: add more specific platform device
IDs) added "armv6-pmu", "armv7-pmu", and "xscale-pmu" platform device
IDs, enabling the three to be distinguished. This series updates
platform code to use these strings.

A later patch series will decouple the drivers.

Since v1 [1]:
* Rebase to v3.19-rc4.
* Add Acks.
* Drop vexpress patches (platform code deleted).

Simon, in v1 you mentioned you were happy to take the shmobile patch
through your tree. Are you still happy to do so, or to give your ack
such that these can go through arm-soc together?

While I'm not too concerned which route these patches take, it would be
nice to have a single base for the patches splitting the drivers.

Thanks,
Mark.

[PATCHv2 1/5] arm: realview: specify PMU types

[Mark Rutland]

Now that we can specify which PMU variant we're likely to deal with, do
so in the realview board code. This will allow us to split the ARMv6,
ARMv7, and XScale PMU drivers.

The Realview EB may be used with ARMv6 or ARMv7 CPUs, but luckily
there's only a single ARMv7 CPU, so we can match that explicitly to
determine whether or not we have an ARMv7 PMU.

Hi Mark,

assuming that this is targeted at v3.20 then it looks like your
changes do not conflict with anything I have queued up and
I am not likely to queue anything more up for the files in question
for that release. As my main concern is about conflicts I'm therefore
quite happy for you to take the shmobile patch through your tree.
I'll supply an ack accordingly.

Thanks, Simon, it's much appreciated.

Arnd, Olof, are you happy to pick this up for v3.20? I believe all the
patches have now been appropriately acked.

If it makes things any easier I've placed the series (with new acks) on
my arm/perf/platform-updates branch [2], based atop of v3.19-rc4.

Thanks,
Mark.

Thanks,
Mark.
