      Merge tag 'omap-for-v5.11/fixes-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes

Fixes for omaps for v5.11-rc cycle

The recent changes to switch SoCs to boot with ti-sysc interconnect
target module driver and genpd caused few regressions:

- The omap_prm reset driver needs to clear any reset bits deasserted by
  the bootloader or kexec boot for the three reset bit cases. Otherwise
  we can have an oops with accelerators starting to boot with potentially
  unconfigured MMU for example

- Custom kernel configs are not automatically selecting simple-pm-bus
  driver that we now need to probe interconnects so we need to select it
  always

- We are not passing legacy platform data in auxdata with simple-pm-bus
  like we do for simple-bus. We need to pass auxdata to simple-pm-bus so
  it can pass it to of_platform_populate()

Then recent RCU changes started causing splats for cpuidle44xx that now
need RCU_NONIDLE added to the calls in several places

And then we have few device specific fixes:

- We need to remove legacy spi-cs-hig for gta04 display to work, and
  set the gpio to active low

- Omap1 specific ohci-omap needs to call gpio_free()

- Droid4 needs to use padconf interrupt for the slider as the edge
  gpio interrupts may be lost for deeper idle states

      tee: optee: replace might_sleep with cond_resched · dcb3b06d
      Rouven Czerwinski authored 
      might_sleep() is a debugging aid and triggers rescheduling only for
certain kernel configurations. Replace with an explicit check and
reschedule to work for all kernel configurations. Fixes the following

      ARM: dts: stm32: Fix GPIO hog flags on DHCOM DRC02 · 83d41122
      Marek Vasut authored 
      The GPIO hog flags are ignored by gpiolib-of.c now, set the flags to 0.
Since GPIO_ACTIVE_HIGH is defined as 0, this change only increases the
correctness of the DT.

      Marek Vasut authored 
      The GPIO hog flags are ignored by gpiolib-of.c now, set the flags to 0.
Due to a change in gpiolib-of.c, setting flags to GPIO_ACTIVE_LOW and
using output-low DT property leads to the GPIO being set high instead.
