+
+It is possible that mdc_tx_status may be called before the first
+node has been read from memory.
+
+In this case, the residue value stored in the register is undefined.
+Return the transfer size instead.

+Subject: spi: img-spfi: Implement dual and quad mode
+
+For dual and quad modes to work the SPFI controller needs
+to have information about command/address/dummy bytes in the
+transaction register. This information is not relevant for
+single mode, and therefore it can have any value in the
+allowed range. Therefore, for any read or write transfers of less
+than 8 bytes (cmd = 1 byte, addr up to 7 bytes), SPFI will be
+configured, but not enabled (unless it is the last transfer in
+the queue). The transfer will be enabled by the subsequent tranfer.
+A pending transfer is determined by the content of the transaction
+register: if command part is set and tsize is not.
+
+This way we ensure that for dual and quad transactions
+the command request size will apear in the command/address part
+of the transaction register, while the data size will be in
+tsize, all data being sent/received in the same transaction (as
+set up in the transaction register).

+Subject: spi: img-spfi: RX maximum burst size for DMA is 8
+
+The depth of the FIFOs is 16 bytes. The DMA request line is tied
+to the half full/empty (depending on the use of the TX or RX FIFO)
+threshold. For the TX FIFO, if you set a burst size of 8 (equal to
+half the depth) the first burst goes into FIFO without any issues,
+but due the latency involved (the time the data leaves the DMA
+engine to the time it arrives at the FIFO), the DMA might trigger
+another burst of 8. But given that there is no space for 2 additonal
+bursts of 8, this would result in a failure. Therefore, we have to
+keep the burst size for TX to 4 to accomodate for an extra burst.
+
+For the read (RX) scenario, the DMA request line goes high when
+there is at least 8 entries in the FIFO (half full), and we can
+program the burst size to be 8 because the risk of accidental burst
+does not exist. The DMA engine will not trigger another read until
+the read data for all the burst it has sent out has been received.
+
+While here, move the burst size setting outside of the if/else branches
+as they have the same value for both 8 and 32 bit data widths.

+Subject: spi: img-spfi: finish every transfer cleanly
+
+Before this change, the interrupt status bit that signaled
+the end of a tranfers was cleared in the wait_all_done
+function. That functionality triggered issues for DMA
+duplex transactions where the wait function was called
+twice, in both the TX and RX callbacks.
+
+In order to fix the issue, clear all interrupt data bits
+at the end of a PIO transfer or at the end of both TX and RX
+duplex transfers, if the transfer is not a pending tranfer
+(command waiting for data). After that, the status register
+is checked for new incoming data or new data requests to be
+signaled. If SPFI finished cleanly, no new interrupt data
+bits should be set.

+To model this add a fixed divide by 4 clock node in

+Subject: MIPS: DTS: img: marduk: switch mmc to 1 bit mode
+
+The mmc block in Pistachio allows 1 to 8 data bits to be used.
+Marduk uses 4 bits allowing the upper 4 bits to be allocated
+to the Mikrobus ports. However these bits are still connected
+internally meaning the mmc block recieves signals on all data lines
+and seems the internal HW CRC checks get corrupted by this erroneous
+data.
+
+We cannot control what data is sent on these lines because they go
+to external ports. 1 bit mode does not exhibit the issue hence the
+safe default is to use this. If a user knows that in their use case
+they will not use the upper bits then they can set to 4 bit mode in
+order to improve performance.
+
+Also make sure that the upper 4 bits don't get allocated to the mmc
+driver (the default is to assign all 8 pins) so they can be allocated
+to other drivers. Allocating all 4 despite setting 1 bit mode as this
+matches what is there in hardware.

+Subject: [PATCH 901/904] MIPS: DTS: img: marduk: Add SPI NAND flash
+
+Add Gigadevice GD5F4GQ4UCYIGT SPI NAND flash to the device tree.
+
+The NAND flash chip is connected with quad SPI, but reading currently
+fails in quad SPI mode.
