-Subject: MIPS: DTS: img: add device tree for Marduk board
-
-Add support for Imagination Technologies' Marduk board which is based
-on Pistachio SoC. It is also known as Creator Ci40. Marduk is legacy
-name and will be there for decades.
-
-Documentation for this board can be found on
-https://docs.creatordev.io/ci40/
-
-This patch adds initial support for board with following peripherals:
-
-* PWM based heartbeat LED
-* GPIO based buttons
-* SPI NOR flash on SPI1
-* UART0 and UART1
-* SD card
-* Ethernet
-* USB
-* PWM
-* ADC
-* I2C
-
-(apply from https://patchwork.linux-mips.org/project/linux-mips/list/?submitter=7165)

-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.

-Subject: clockevents: Retry programming min delta up to 10 times
-
-Under virtualisation it is possible to get unexpected latency during a
-clockevent device's set_next_event() callback which can make it return
--ETIME even for a delta based on min_delta_ns.
-
-The clockevents_program_min_delta() implementation for
-CONFIG_GENERIC_CLOCKEVENTS_MIN_ADJUST=n doesn't handle retries when this
-happens, nor does clockevents_program_event() or its callers when force
-is true (for example hrtimer_reprogram()). This can result in hangs
-until the clock event device does a full period.
-
-It isn't appropriate to use MIN_ADJUST in this case as occasional
-hypervisor induced high latency will cause min_delta_ns to quickly
-increase to the maximum.
-Instead, borrow the retry pattern from the MIN_ADJUST case, but without
-making adjustments. We retry up to 10 times before giving up.

-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: mtd: nand: Check length of ID before reading bits per cell
-
-The table-based NAND identification currently reads the number
-of bits per cell from the 3rd byte of the extended ID. This is done
-for the so-called 'full ID' devices; i.e. devices that have a known
-length ID.
-
-However, if the ID length is shorter than three, there's no 3rd byte,
-and so it's wrong to read the bits per cell from there. Fix this by
-adding a check for the ID length.

-Subject: mtd: Introduce SPI NAND framework
-
-Add a new framework, to support SPI NAND devices. The framework registers
-a NAND chip and handles the generic SPI NAND protocol, calling device-specific
-hooks for each SPI NAND command.
-
-The following is the stack design, from userspace to hardware. This commit
-adds the "SPI NAND core" layer.

-From: Ezequiel Garcia <ezequiel.garcia@imgtec.com>
-Date: Tue, 28 Feb 2017 10:37:24 +0000
-Subject: mtd: spi-nand: Support Gigadevice GD5F
-
-This commit uses the recently introduced SPI NAND framework to support
-the Gigadevice GD5F serial NAND device.
-
-The current support includes:
-
- * Page read and page program operations (using on-die ECC)
- * Page out-of-band read
- * Erase
- * Reset
- * Device status retrieval
- * Device ID retrieval
-
-(based on http://lists.infradead.org/pipermail/linux-mtd/2014-December/056769.html)
