Merge tag 'spi-fix-v6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi fixes from Mark Brown: "There's two things here - the big one is a batch of fixes for the power management in the Cadence QuadSPI driver which had some serious issues with runtime PM and there's also a revert of one of the last batch of fixes for ppc4xx which has a dependency on -next but was in between two mainline fixes so the -next dependency got missed. The ppc4xx driver is not currently included in any defconfig and has dependencies that exclude it from allmodconfigs so none of the CI systems catch issues with it, hence the need for the earlier fixes series. There's some updates to the PowerPC configs to address this" * tag 'spi-fix-v6.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi: Drop mismerged fix spi: cadence-qspi: add system-wide suspend and resume callbacks spi: cadence-qspi: put runtime in runtime PM hooks names spi: cadence-qspi: remove system-wide suspend helper calls from runtime PM hooks spi: cadence-qspi: fix pointer reference in runtime PM hooks
