Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal, disabling SPI leads to messages like: Powerdomain (core_pwrdm) didn't enter target state 0 and according to /sys/kernel/debug/pm_debug/count off state is not entered. That was not connected to SPI during the discussion of disabling SPI. See: https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/ Fix excess DMA channel usage by disabling DMA only instead of disabling the SPI modules, so powermanagement can da all its work.
