Merge tag 'spi-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
"One small core feature this time around but mostly driver improvements
and additions for SPI:
- Add support for controlling the idle state of MOSI, some systems
can support this and depending on the system integration may need
it to avoid glitching in some situations
- Support for polling mode in the S3C64xx driver and DMA on the
Qualcomm QSPI driver
- Support for several Allwinner SoCs, AMD Pensando Elba, Intel Mount
Evans, Renesas RZ/V2M, and ST STM32H7"
