spi: Fix DMA mapping ownership on partial map failure (2026-08-14 16:48:53 +0100)
----------------------------------------------------------------
spi: Updates for v7.3
Along with a lot of driver specific work we've got a couple of core
features here. The bigger one is that we've now got support for
instantiating devices from sysfs similarly to how it's already done for
I2C, this is used with development boards with non-enumerable expansion
headers since SPI devices need to be manually specified. We also have
support for the DQS signal on higher end flash devices.
- Support for intantiating devices from sysfs, useful for development
boards with non-enumerable plugin modules, from Vishwaroop A.
- Support for DQS in spi-mem, an additional signal used by flash
devices to avoid clock skew from Miquel Raynal.
- Support for more advanced SPI modes on DesignWare controllers from
Sudip Mukherjee.
- Changes from Jisheng Zhang to update to modern methods of specifying
the PM callbacks.
- Fixes for DMA mapping error handling, plus KUnit tests for this, from
Honghui Jiang.
- Substantial cleanup and performance work in the nxp-spi driver.
- Support for Microchip LAN969x, Nuvoton MA35D1 QSPI, Qualcomm SA8255p
and SA8797P, and StarFive JHB100 SFC.
There is a trivial add/add conflict with the KUnit tree in their
all_tests.config.
