Hi all,

This patch set extends PPMU on Samsung Exynos by choosing type of data
which shell be counter in the PPMU registers.
It is possible to count e.g. read or write requests, read or write data.
A new field has been added in the DT 'event' node called 'event-data-type'.
It is them used during the setup of the counter. In the prevoius
implementation there was always one option used: count read+write data.
Sometimes we need more precised information and this patch set tries to
address it.

Regards,
Lukasz Luba
