v5: Incorporate feedback from Mark Brown and Geert Uytterhoeven
spi: qup: Enable chip select support Update commit log. Include the commit's description
Removed "spi: qup: Add completion structures for DMA". This introduced separate completion structures for DMA based rx/tx and FIFO based i/os. This was not needed.
Added "spi: qup: Fix QUP version identify method" to identify qup version using of_device_get_match_data instead of of_device_is_compatible.
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 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 spi: qup: Fix QUP version identify method
