X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d07c3df8019bf01306065c4271421d70ad23e5e8;p=linux-beck.git ARM: OMAP: dma: Make use of cpu_class_is_omap2() to avoid future patching. cpu_class_is_omap2() contains all OMAP2+ devices. So update the DMA code cpu checks accordingly so that there is no need to patch the file for any future OMAP2+ devices. In long run, all these attributes should come from hwmod dev_attr based on DMA IP version.
