Merge tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes

Few ti-sysc related fixes for v5.5 merge window

Just few minor changes that can be merged when suitable, but would
be good to have these in v5.5-rc1 to remove dependencies between branches
for more changes later on in v5.6:

- Add quirk handling for AESS (Audio Engine Sub System)

- We want to drop the useless gptimer option for omap4 as there are local
  timers

- A minor error path handling improvment for sysc_child_add_named_clock()
  that will make further patching a bit easier

* tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  bus: ti-sysc: Adjust exception handling in sysc_child_add_named_clock()
  ARM: OMAP2+: Drop useless gptimer option for omap4
  bus: ti-sysc: Add module enable quirk for audio AESS
