Hi Shimoda-san,
I now upported this patch 55d2d2fb8b04 ("i2c: rcar: Fix I2C DMA
transmission by setting sequence") with this series:https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=87931 The issue of the BSP patch was understandable, but I think my refactored version needs less computation and is hopefully easy to understand, too. I did all the tests I can think of and had no regressions. But maybe the BSP team also wants to have a look at this series to check if it matches their needs? Thank you and happy hacking! Wolfram
