These low-power link states, designed to reduce power consumption during idle periods, can cause issues in latency-sensitive or high throughput use cases. Over the years, some of the issues seen are as follows: 1. In device mode of operation, when UVC is active, enabling U1/U2 is sometimes causing packets drops due to delay in entry/exit of intermittent these low power states. These packet drops are often reflected as missed isochronous transfers, as the controller wasn't able to send packet in that microframe interval and hence glitches are seen on the final transmitted video output. 2. On older targets like SM8150/SM8250/SM8350, there have been throughput issues seen during tethering use cases. 3. On targets like SDX75, intermittent disconnects were observed with certain cables due to impedence variations. Disabling these intermittent power states enhances device stability without affecting power usage.

This enables USB devices to be ready for use faster and reduces wear and risk of data loss on storage devices. A particularly annoying case was booting from a mechanical disk, which takes time to spin up again. Vendor kernel also kept these ports powered, and by the same means.

The block may be used as DMA engine for some of the peripherals (maybe the EMMC controller found in the same group of peripherals?) but it can always be used as a memcpy engine, which is a generic "blitter". I tested it with the dmatest module, and it copies lots of data very fast and fires hundreds of thousands of interrupts so it works just fine. Add it to the BCM6846 DTSI file.
