This series adds support for DMA during QSPI flash read via memory mapped mode. The first patch adds a check to spi_map_buf() API to return error when kmap'd buffers are passed for DMA mapping. Second patch adds support for using DMA on top of spi_flash_read() API using DMA sg_table mapping support in SPI core. Third map adds DMA support for TI QSPI in memory mapped read mode. Tested on DRA74 EVM and DRA72 EVM on linux-next. v1: https://lkml.org/lkml/2016/4/4/855 Vignesh R (3): spi: return error if kmap'd buffers passed to spi_map_buf() spi: Add DMA support for spi_flash_read() spi: spi-ti-qspi: Add DMA support for QSPI mmap read drivers/spi/spi-ti-qspi.c | 196 +++++++++++++++++++++++++++++++++++++++++++--- drivers/spi/spi.c | 18 ++++- include/linux/spi/spi.h | 4 + 3 files changed, 204 insertions(+), 14 deletions(-) -- 2.8.1
