Merge tag 'spi-v6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"A moderately busy release for SPI, the main core update was the
merging of support for multiple chip selects, used in some flash
configurations. There were also big overhauls for the AXI SPI Engine
and PL022 drivers, plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with
submitting messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas
RZ/Five"
