When the DMA must perform read/write accesses, the DMADISABLE bit is cleared by the hardware. But when the DMA must stop for power management, software must set the DMADISABLE bit back to 1. In cases where the ROMCODE/BOOTLOADER uses dma, the hardware clears the DMADISABLE bit (but the romcode/bootloader might not set it back to 1). In order for the kernel to start in a clean state, it is necessary for the kernel to set DMADISABLE bit back to 1 (irrespective of whether it's been set to 1 in romcode or bootloader). During _reset of the (hwmod)device, the DMADISABLE bit is set so that it does not prevent idling of the system. (NOTE: having DMADISABLE to 0, prevents the system to idle) DMADISABLE bit is present in usbotgss module of omap5.

But while adding complete baseport support (like, clock, power and hwmod) support, it is observed that, we are creating more and more problems by treating am33xx device as omap3 family, as nothing matches between them (except cortex-A8 mpu). So, after long discussion we have came to the conclusion that, we should not consider am33xx device as omap3 family, instead create separate class (SOC_AM33XX) under OMAP2PLUS. This means, for am33xx device, cpu_is_omap34xx() will return false, and only cpu_is_am33xx() will be true.
