Martin Hicks 833b51170f mmc: Throttle calls to MMC_SEND_STATUS during mmc_do_erase() ... This drastically reduces the rate at which the MMC_SEND_STATUS cmd polls for completion of the MMC Erase operation. The patch does this by adding a backoff sleep that starts by sleeping for short intervals (128-256us), and ramps up to sleeping for 32-64ms. Even on very quickly completing erase operations, the loop iterates a few times, so not too much extra latency is added to these commands. For long running discard operarations, like a full-device secure discard, this change drops the interrupt rates on my single-core NXP I.MX6UL from 45000/s to about 20/s, and greatly improves system responsiveness.
