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
