Hi, this series is based on work by Ai Kyuse to add UHS-I SDR-104 support for sh_mobile_sdhi. It builds on work by Shinobu Uehara, Rob Taylor, William Towle and Ian Molton, Ben Hutchings, Wolfram Sang and others to add UHS-I SDR-50 support to the same driver. This series enables UHS-I SDR-104 on the r8a7790/Lager where UHS-I SDR-50 is already enabled. It is based on the next branch of the mmc tree The first three mmc driver patches are targeted at the next branch of the mmc tree. The last DT patch is targeted at the devel branch of the renesas tree. To aid review this series is provided in the temporary topic/sdr104-v4 branch of the renesas tree. Changes since previous versions are described in individual patches. In this patchset I have attempted to address all review received for the v3 patch-set. I also believe that I have resolved a problem where tuning would timeout under some circumstances: this seems to have been due to several bugs introduced between v1 and v3. Please see http://elinux.org/Tests:SD-SDHI-SDR104 for indicative tests results. Highlights follow: * Currently I am seeing speeds of up to 48MB/s with these patches and 30MB/s without using a SanDisk Extreme Pro 8Gb microSDHC UHS-1 card. * I am also seeing 45MB/s with these patches and 34MB/s without using a SanDisk Ultra 64Gb microSDXC UHS-1 card. The above results are the same as previously reported for v2 and v3 of this patchset.
