Merge tag 'spi-fix-v6.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi

Pull spi fixes from Mark Brown:
"A small collection of fixes that came in during the past week, a few
driver specifics plus one fix for the spi-mem core where we weren't
taking account of the frequency capabilities of the system when
determining if it can support an operation"

* tag 'spi-fix-v6.17-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
spi: st: fix PM macros to use CONFIG_PM instead of CONFIG_PM_SLEEP
spi: spi-qpic-snand: fix calculating of ECC OOB regions' properties
spi: spi-fsl-lpspi: Clamp too high speed_hz
spi: spi-mem: add spi_mem_adjust_op_freq() in spi_mem_supports_op()
spi: spi-mem: Add missing kdoc argument
spi: spi-qpic-snand: use correct CW_PER_PAGE value for OOB write
