From: Boris Brezillon Date: Wed, 11 May 2016 09:00:02 +0000 (+0200) Subject: ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC X-Git-Tag: v4.5.5~36 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bef800fb18cba0052314ef90c3f278db500e5490;p=thirdparty%2Fkernel%2Fstable.git ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC 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.
