[PATCH 4.5 066/101] ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC

From: Greg Kroah-Hartman

4.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx>

commit aab0a4c83ceb344d2327194bf354820e50607af6 upstream.

The memory range assigned to the PMC (Power Management Controller) was
not including the PMC_PCR register which are used to control peripheral
clocks.

This was working fine thanks to the page granularity of ioremap(), but
started to fail when we switched to syscon/regmap, because regmap is
making sure that all accesses are falling into the reserved range.
