Just saw a missing update, i am sending a v4.

From: Patrice Chotard <patrice.chotard@foss.st.com> This series adds support for the spi_mem_poll_status() spinand interface. 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. Chnages in v3: - Add spi_mem_read_status() which allows to read 8 or 16 bits status. - Add initial_delay_us and polling_delay_us parameters to spi_mem_poll_status(). and also to poll_status() callback. - Move spi_mem_supports_op() in SW-based polling case. - Add delay before invoquing read_poll_timeout(). - Remove the reinit/wait_for_completion() added in v2. - Add initial_delay_us and polling_delay_us parameters to spinand_wait(). - Add SPINAND_READ/WRITE/ERASE/RESET_INITIAL_DELAY_US and SPINAND_READ/WRITE/ERASE/RESET_POLL_DELAY_US defines. - Remove spi_mem_finalize_op() API added in v2. 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 management 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 | 45 +++++++++++++------ drivers/spi/spi-mem.c | 85 ++++++++++++++++++++++++++++++++++++ drivers/spi/spi-stm32-qspi.c | 83 +++++++++++++++++++++++++++++++---- include/linux/mtd/spinand.h | 11 ++++- include/linux/spi/spi-mem.h | 14 ++++++ 5 files changed, 216 insertions(+), 22 deletions(-)
