Some QSPI controllers allows to poll automatically memory status during operations (erase, read or write). This allows to offload the CPU for this task. STM32 QSPI is supporting this feature, driver update are also part of this series. Changes in v2: - Indicates the spi_mem_poll_status() timeout unit - Use 2-byte wide status register - Add spi_mem_supports_op() call in spi_mem_poll_status() - Add completion management in spi_mem_poll_status() - Add offload/non-offload case mangement in spi_mem_poll_status() - Optimize the non-offload case by using read_poll_timeout() - mask and match stm32_qspi_poll_status()'s parameters are 2-byte wide - Make usage of new spi_mem_finalize_op() API in stm32_qspi_wait_poll_status() Patrice Chotard (3): spi: spi-mem: add automatic poll status functions mtd: spinand: use the spi-mem poll status APIs spi: stm32-qspi: add automatic poll status feature drivers/mtd/nand/spi/core.c | 17 ++++---- drivers/spi/spi-mem.c | 71 +++++++++++++++++++++++++++++++ drivers/spi/spi-stm32-qspi.c | 81 ++++++++++++++++++++++++++++++++---- include/linux/mtd/spinand.h | 1 + include/linux/spi/spi-mem.h | 10 +++++ 5 files changed, 164 insertions(+), 16 deletions(-) -- 2.17.1
