Read Transfer Active/ Write Transfer Active may be not de-asserted after end of transaction. 2. Slow interrupt clearance at 400KHz may cause host driver interrupt handler to be called twice. 3. Controller does not support tuning commands as defined in SD 3.0 spec and CMD CRC errors are expected for tuning commands. 4. Improve the speed of secure discard operations by not using the calculated value, but the default one instead. 5. Controller can not handle large timeout values for R1B commands. Patches are based on v3.11-rc5.
