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 a merge of the next branches of the mmc and renesas trees. 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 are provided: * https:://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git topic/sdr104-v6 This patch set * https:://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git topic/sdr104-v6+sdhi-dma-v3 This patch set merged with a rebase of prototype DMA support for SDHI on R-Car Gen 3 Overview of changes since v5: * Drop retune handling from tmio suspend handler: it hs handled by MMC core * Allow restoration of saved tuning parameters on resume Please see http://elinux.org/Tests:SD-SDHI-SDR104 for indicative tests results.
