Subject: ARM: OMAP2xxx: hwmod: Add DMA support for SHAM module
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fa7807b4cc77376b3ec245f8663201780e6c7450;p=linux-beck.git

ARM: OMAP2xxx: hwmod: Add DMA support for SHAM module

The current OMAP2 SHAM support doesn't enable DMA
so add that support so it can use DMA just like OMAP3.
