CN3860 does not interrupt the CPU when the i2c status changes. If
we get a timeout, and see the status has in fact changed, we know we
have this problem, and drop back to polling.

cn78XX has a different interrupt architecture, so we have to manage

The implemented Cortex A57 events are not A57 specific.
They are recommended by ARM and can be found on other
ARMv8 SOCs like Cavium ThunderX too. Therefore move
these events to the common PMUv3 table.

counter always sets the upper
32 bits so overflow interrupts are generated as before.

ARMv8.1 increases the PMU event number space. Detect the
presence of this PMUv3 type and extend the event mask.
The event mask is moved to struct arm_pmu so different event masks
can exist, depending on the PMU type.

Hi Mark & Will,
I'm resending the arm64 PMU patches. The only difference to the first
version is that I dropped the x on thunder in order to be consistent
with the existing device tree name.
Thanks,
Jan

The ThunderX SOC uses the same i2c block as the Octeon SOC.
The main difference is that on ThunderX the device is a PCI device
so device probing is done via PCI.
Split the current Octeon driver into an Octeon and a common part
and add the ThunderX support.
