v6:
	Fix git bisect-ability issues in
		spi: qup: Add completion timeout
		spi: qup: call io_config in mode specific function
		spi: qup: allow multiple DMA transactions per spi xfer

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.
