-Subject: dmaengine: img-mdc: Handle early status read
-
-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.

-
-The SDHost currently clocks the card 4x slower than it
-should do, because there is fixed divide by 4 in the
-sdhost wrapper that is not present in the clock tree.
-To model this add a fixed divide by 4 clock node in
-the SDHost clock path.
-
-This will ensure the right clock frequency is selected when
-the mmc driver tries to configure frequency on card insert.

-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.
