[PATCH 0/5] mmc: sdhci: Add quirks for Qualcomm MSM SDHCI controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset adds quirks for various workarounds and performance
improvements required for Qualcomm MSM SDHCI driver.

1. 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.
