      Chris Brandt authored
      The SDHI/MMC controller in the RZ/A2 is almost the same as R-Car gen3, but
      with some minor differences.

      mmc: atmel-mci: do not assume idle after atmci_request_end · ae460c11
      Jonas Danielsson authored
      On our AT91SAM9260 board we use the same sdio bus for wifi and for the
      sd card slot. This caused the atmel-mci to give the following splat on
      the serial console:

      This is:
        WARN_ON(host->cmd);
      
      This was fixed on our board by letting atmci_request_end determine what
      state we are in. Instead of unconditionally setting it to STATE_IDLE on
      STATE_END_REQUEST.

      mmc: dw_mmc-bluefield: simplify the probe() function · 3df407b2
      Liming Sun authored
      This commit removes the unnecessary of-node check since the
      dw_mci_bluefield_match[] structure has only one entry.
