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.
* Both UHS-1 SDR-50 and SDR-104 on the r8a7796/Salvator-X
It is based on the next branch of the mmc tree
The "mmc:" patches are targeted at the next branch of the mmc
tree. The "ARM:" and "arm64:" patches are targeted at the next branch of
the renesas tree.
To aid review the following git branches have been provided:
* topic/sdr104-v4 branch: This patchset
* topic/sdr104-v5+sdhi-dma-v3: This patchset merged with a rebase of
prototype DMA support for SDHI on R-Car Gen 3
Overview of changes since v4:
* Addressed review from Ulf Hansen
* Add Gen 3 support and enable on r8a7796/Salvator-X
TODO:
* Continue investigation of using saved tap values on resume
from suspend

results.
