Subject: ARM: OMAP: dma: Make use of cpu_class_is_omap2() to avoid future patching.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d07c3df8019bf01306065c4271421d70ad23e5e8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.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.
