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
