Subject: OMAP3: PM: fix scratchpad memory accesses for off-mode
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=de65815860f187cb43551bc833bf9d72720faa01;p=linux-beck.git

OMAP3: PM: fix scratchpad memory accesses for off-mode

Commit 914bab936fe0388a529079679e2f137aa4ff548d (OMAP: mach-omap2: Fix
incorrect assignment warnings) changed a pointer from 'u32 *' to
'void *' without also fixing up the pointer arithmetic.

Fix the scratchpad offsets so they are byte offsets instead of
word offsets and thus work correctly with a void pointer base.

Special thanks to Jean Pihet for taking the time track down this
problem and propose an initial solution.

Tested with off-idle and off-suspend on 36xx/Zoom3 and 34xx/omap3evm.
