The IP is shared on PPC and ARM, this rename it to qoriq for better
represention, and this also add the CLK_OF_DECLARE support for being
initialized by of_clk_init() on ARM.

This patch removes the redundant sysfs cacheinfo code by making use of
the newly introduced generic cacheinfo infrastructure.

This series adds a generic cacheinfo support similar to topology. The
implementation is based on x86 cacheinfo support. Currently x86, powerpc,
ia64 and s390 have their own implementations. While adding similar support

From: Sudeep Holla
This patch adds initial support for providing processor cache information
to userspace through sysfs interface. This is based on already existing
implementations(x86, ia64, s390 and powerpc) and hence the interface is
intended to be fully compatible.

Hi folks !
I've been tracking down some problems with the recent DRI on powerpc and
stumbled upon something that doesn't look right, and not necessarily
only for us.
Now it's possible that I haven't fully understood the code here and I
also don't know to what extent some of that behaviour is nece

Hit this on a Power8 LPAR. With the patch
LS1 is arm cpu and it has qe ip block.
move qe code from platform directory to public directory.
QE is an IP block integrates several comunications peripheral

In the PAMU driver we were again adding the device to the same group without
checking
if the device already had an iommu group. This resulted in the following
warning.
