comments:
  - "planned for Q2/19"
  - "probably MMC core should call hs400_complete() before mmc_send_status() first, according to Shimoda-san"
  - "calling hs400_complete first: now merged"
  - "v1: https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=140049"
  - "Shimoda-san requested to wait because another HS400 issue is investigated at Renesas which will likely affect this series"
  - "still waiting for info from HW team"
  - "additional task was considered completed. Follow-up work depending on info from HW team is still needed, though"
  - "new code released in BSP 3.9.7. Needs to be refactored for upstream"
  - "So, we manage further actions on bsp397_SDHI and this gets marked Done"
