v1: This series fixes some existing issues in the code for both interrupt and dma mode. Patches 1 - 11 are the fixes. Random failures/timeout are observed without these fixes. Also, the current driver does not support block transfers > 64K and the driver quietly fails. Patches 12 - 18 add support for this in both interrupt and dma mode. The entire series has been tested on ipq4019 with SPI-NOR flash for block sizes > 64k. Varadarajan Narayanan (18): spi: qup: Enable chip select support spi: qup: Setup DMA mode correctly spi: qup: Add completion timeout for dma mode spi: qup: Add completion timeout for fifo/block mode spi: qup: Place the QUP in run mode before DMA transactions spi: qup: Fix error handling in spi_qup_prep_sg spi: qup: Fix transaction done signaling spi: qup: Handle v1 dma completion differently spi: qup: Do block sized read/write in block mode spi: qup: Fix DMA mode interrupt handling spi: qup: properly detect extra interrupts spi: qup: refactor spi_qup_io_config into two functions spi: qup: call io_config in mode specific function spi: qup: allow block mode to generate multiple transactions spi: qup: refactor spi_qup_prep_sg spi: qup: allow multiple DMA transactions per spi xfer spi: qup: Ensure done detection spi: qup: support for qup v1 dma .../devicetree/bindings/spi/qcom,spi-qup.txt | 6 + drivers/spi/spi-qup.c | 639 +++++++++++++++------ 2 files changed, 462 insertions(+), 183 deletions(-) -- QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
