Merge tag 'omap-for-v5.13/fixes-pm' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes

PM and build warning fixes for omaps

While chasing system suspend related regressions, I noticed few other
issues related to PM would be good to have fixed:

- UART idling does not always work for hardware autoidle features
- am335x resume works only the first time unless musb module is loaded

Then there are three patches for omap1 related warnings caused by the gpio
changes, and one build warning fix for legacy mmc platform code when mmc
is built as a loadable module.

These can all be merged whenever suitable naturally. I've sent the more
urgent SATA regression fix separately although it appears in this pull
request too because of the branches merged.

* tag 'omap-for-v5.13/fixes-pm' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP1: ams-delta: remove unused function ams_delta_camera_power
  bus: ti-sysc: Fix flakey idling of uarts and stop using swsup_sidle_act
  bus: ti-sysc: Fix am335x resume hang for usb otg module
  ARM: OMAP2+: Fix build warning when mmc_omap is not built
  ARM: OMAP1: isp1301-omap: Add missing gpiod_add_lookup_table function
  ARM: OMAP1: Fix use of possibly uninitialized irq variable
