Hi Mark, Cc: Geert, Sergei Thanks for your comments and advices. I separated my patch into two patches as you've shown me. These patches fix: 3be09bec42a800d4 "spi: rspi: supports 32bytes buffer for DUAL and QUAD". One of them is to fix bogus received byte into qspi_transfer_in(), and other is to replace "n" by "len" bytes of data in qspi_transfer_in()and qspi_transfer_out(). These patches were tested at v4.10-rc8 on Renesas Gen2 Lager board. Please consider these patches to Renesas Rcar family. Thank you. Jinso/Dong.
