OMAP GPIOs have many usages or use cases, so we can use gpiolib

Now this kind of DMA controllers are only used by MUSB or only for
MUSB, so it doesn't matter to access them by dmaengine or not.
Not entirely true. TUSB uses OMAP system DMA and AFAICT CPPI is used
also for ethernet.
Yes, but the CPPI registers are not compatible between MUSB and EMAC, only
the descriptors are, AFAIK.
