2022-04-19spi: spi-imx: add support for SPI_RX_CPHA_FLIPBaruch Siach
When SPI_RX_CPHA_FLIP is set, flip CPHA on Rx only transfers. This is useful to access devices that use inverted CPHA for MISO vs MOSI signals. Only support the mx51/mx53 variants for now. Tested on i.MX6ULL based system.

Some SPI devices latch MOSI bits on one clock phase, but produce valid MISO bits on the other phase. Add SPI_RX_CPHA_FLIP mode to instruct the controller driver to flip CPHA for Rx (MISO) only transfers.

2022-04-13spi: cadence-quadspi: fix incorrect supports_op() return valueMatthias Schiffer
Since the conversion to spi-mem, the driver advertised support for various operations that cqspi_set_protocol() was never expected to handle correctly - in particuar all non-DTR operations with command or address buswidth > 1. For DTR, all operations except for 8-8-8 would fail, as cqspi_set_protocol() returns -EINVAL. In non-DTR mode, this resulted in data corruption for SPI-NOR flashes that support such operations. As a minimal fix that can be backported to stable kernels, simply disallow the unsupported operations again to avoid this issue.

2022-04-12spi: spi-rspi: Remove setting {src,dst}_{addr,addr_width} based on DMA directionBiju Das
The direction field in the DMA config is deprecated. The rspi driver sets {src,dst}_{addr,addr_width} based on the DMA direction and it results in dmaengine_slave_config() failure as RZ DMAC driver validates {src,dst}_addr_width values independent of DMA direction. This patch fixes the issue by passing both {src,dst}_{addr,addr_width} values independent of DMA direction.

2022-04-12spi: core: Only check bits_per_word validity when explicitly providedPaul Kocialkowski
On SPI device probe, the core will call spi_setup in spi_add_device before the corresponding driver was probed. When this happens, the bits_per_word member of the device is not yet set by the driver, resulting in the default being set to 8 bits-per-word. However some controllers do not support 8 bits-per-word at all, which results in a failure when checking the bits-per-word validity. In order to support these devices, skip the bits-per-word validity check when it is not explicitly provided by drivers.

2022-04-05spi: spidev: replace usage of found with dedicated list iterator variableJakob Koschel
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-04-02Revert "clk: Drop the rate range on clk_put()"Stephen Boyd
This reverts commit 7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are multiple reports that this breaks boot on various systems. The common theme is that orphan clks are having rates set on them when that isn't expected. Let's revert it out for now so that -rc1 boots.

This log message was accidentally chopped off. I was wondering why this happened, but checking the ML log, Mark precisely followed my suggestion [1]. I just used "..." because I was too lazy to type the sentence fully. Sorry for the confusion.
