While testing the eMMC access in a Banana Pi M3, I found and fixed
some problems:
- the driver was trying to set a strange rate when clk_round_rate()
  was returning an error
- the 'new timing mode' could not work because a register was not set
- with a parent clock at 1.2GHz, the output and sample phases were
  not correct for the A83T

Jean-Francois Moine (3):
  mmc: sunxi: Check the value returned by clk_round_rate
  mmc: sunxi: Set the 'New Timing' register for 8 bits DDR transfers
  mmc: sunxi: Add support to the Allwinner A83T
