v4: Discard patch #15, 'spi: qup: support for qup v1 dma'. This depends on ADM driver, which is not upstreamed yet. v3: Fix git bisect-ability issues in spi: qup: Add completion structures for DMA spi: qup: Add completion timeout spi: qup: Place the QUP in run mode before DMA spi: qup: Fix transaction done signaling v2: Incorporate feedback from Andy Gross, Sricharan, Stanimir Varbanov Modified the QUP-v1 dma completion sequence to QUP-v2 as per feedback. Removed code that used controller->xfer to identify extra interrupts, since with the fixes done to handle i/o completion we don't see extra interrupts. 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 (14): spi: qup: Enable chip select support spi: qup: Setup DMA mode correctly spi: qup: Add completion structures for DMA spi: qup: Add completion timeout spi: qup: Place the QUP in run mode before DMA spi: qup: Fix error handling in spi_qup_prep_sg spi: qup: Fix transaction done signaling spi: qup: Do block sized read/write in block mode 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 drivers/spi/spi-qup.c | 597 ++++++++++++++++++++++++++++++++++---------------- 1 file changed, 408 insertions(+), 189 deletions(-) -- QUALCOMM INDIA, on behalf of Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation
