[2/2] spi: cadence-quadspi: Fix check condition for DTR ops commit: 0395be967b067d99494113d78470574e86a02ed4 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
Hi, This series proposes fixes for cadence-quadspi controller for the following issues with SPI NAND flashes: - Due to auto-HW polling without address phase, the cadence-quadspi controller timeouts when performing any write operation on SPI NAND flash. - When checking for DTR spi_mem_op, cadence-quadspi doesn't ignore a zero length phase in the SPI instruction, resulting in false negatives. This series has been tested on TI J721e EVM with the Winbond W35N01JW flash. v1 series: https://lore.kernel.org/linux-spi/20210713125743.1540-1-a-nandan@ti.com/ Changes in v2: - [PATCH v2 1/2]: Same as v1. This patch has been already applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next commit 9cb2ff111712 ("spi: cadence-quadspi: Disable Auto-HW polling") - [PATCH v2 2/2]: Add new comments to explain the DTR check conditions Apurva Nandan (2): spi: cadence-quadspi: Disable Auto-HW polling spi: cadence-quadspi: Fix check condition for DTR ops drivers/spi/spi-cadence-quadspi.c | 48 ++++++++++++++++++++----------- 1 file changed, 32 insertions(+), 16 deletions(-)
