Subject: [POWERPC] Fix storcenter DTS typos, feedback, IRQs.
X-Git-Tag: v2.6.25-rc1~303^2~25^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0367aad1ad5f8085ed15e9e30604f50108a1ea06;p=linux-2.6

[POWERPC] Fix storcenter DTS typos, feedback, IRQs.

Cleaned up IRQ layout and removed unsused ISU allocations.
Fixed RTC address typo from /dts-v1/ conversion.
Incorporated list suggestions to use an "iomega," vendor prefix,
and to use a node reference rather than a hard path.
