01c7523fc3 ARM: dts: imx6sx-nitrogen6sx: Use #pwm-cells = <3> for imx27-pwm device
The binding dictates using 3 pwm-cells. Adhere to that.

This fixes the following dtbs_check warning:

	arch/arm/boot/dts/nxp/imx/imx6sx-nitrogen6sx.dtb: pwm@208c000: #pwm-cells:0:0: 3 was expected
		from schema : http://devicetree.org/schemas/pwm/imx-pwm.yaml#

There is no need for an explicit status = "okay" in the pwm node as
the soc dtsi doesn't disable this device. Drop this property, too.

080297becc arm64: defer clearing DAIF.D
For historical reasons we unmask debug exceptions in __cpu_setup(), but
it's not necessary to unmask debug exceptions this early in the
boot/idle entry paths. It would be better to unmask debug exceptions
later in C code as this simplifies the current code and will make it
easier to rework exception masking logic to handle non-DAIF bits in
future (e.g. PSTATE.{ALLINT,PM}).

We started clearing DAIF.D in __cpu_setup() in commit:

  2ce39ad151 ("arm64: debug: unmask PSTATE.D earlier")

At the time, we needed to ensure that DAIF.D was clear on the primary
CPU before scheduling and preemption were possible, and chose to do this
in __cpu_setup() so that this occurred in the same place for primary and
secondary CPUs. As we cannot handle debug exceptions this early, we
placed an ISB between initializing MDSCR_EL1 and clearing DAIF.D so that
no exceptions should be triggered.

Subsequently we rewrote the return-from-{idle,suspend} paths to use
__cpu_setup() in commit:

  cabe1c81ea ("arm64: Change cpu_resume() to enable mmu early then access sleep_sp by va")

... which allowed for earlier use of the MMU and had the desirable
property of using the same code to reset the CPU in the cold and warm
boot paths. This introduced a bug: DAIF.D was clear while
cpu_do_resume() restored MDSCR_EL1 and other control registers (e.g.
breakpoint/watchpoint control/value registers), and so we could
unexpectedly take debug exceptions.

We fixed that in commit:

  744c6c37cc ("arm64: kernel: Fix unmasked debug exceptions when restoring mdscr_el1")

... by having cpu_do_resume() use the `disable_dbg` macro to set DAIF.D
before restoring MDSCR_EL1 and other control registers. This relies on
DAIF.D being subsequently cleared again in cpu_resume().

Subsequently we reworked DAIF masking in commit:

  0fbeb31875 ("arm64: explicitly mask all exceptions")

... where we began enforcing a policy that DAIF.D being set implies all
other DAIF bits are set, and so e.g. we cannot take an IRQ while DAIF.D
is set. As part of this the use of `disable_dbg` in cpu_resume() was
replaced with `disable_daif` for consistency with the rest of the
kernel.

These days, there's no need to clear DAIF.D early within __cpu_setup():

* setup_arch() clears DAIF.DA before scheduling and preemption are
  possible on the primary CPU, avoiding the problem we we originally
  trying to work around.

  Note: DAIF.IF get cleared later when interrupts are enabled for the
  first time.

* secondary_start_kernel() clears all DAIF bits before scheduling and
  preemption are possible on secondary CPUs.

  Note: with pseudo-NMI, the PMR is initialized here before any DAIF
  bits are cleared. Similar will be necessary for the architectural NMI.

* cpu_suspend() restores all DAIF bits when returning from idle,
  ensuring that we don't unexpectedly leave DAIF.D clear or set.

  Note: with pseudo-NMI, the PMR is initialized here before DAIF is
  cleared. Similar will be necessary for the architectural NMI.

This patch removes the unmasking of debug exceptions from __cpu_setup(),
relying on the above locations to initialize DAIF. This allows some
other cleanups:

* It is no longer necessary for cpu_resume() to explicitly mask debug
  (or other) exceptions, as it is always called with all DAIF bits set.
  Thus we drop the use of `disable_daif`.

* The `enable_dbg` macro is no longer used, and so is dropped.

* It is no longer necessary to have an ISB immediately after
  initializing MDSCR_EL1 in __cpu_setup(), and we can revert to relying
  on the context synchronization that occurs when the MMU is enabled
  between __cpu_setup() and code which clears DAIF.D

Comments are added to setup_arch() and secondary_start_kernel() to
explain the initial unmasking of the DAIF bits.

3a2d2ca429 arm64: assembler: update stale comment for disable_step_tsk
A comment in the disable_step_tsk macro refers to synchronising with
enable_dbg, as historically the entry used enable_dbg to unmask debug
exceptions after disabling single-stepping.

These days the unmasking happens in entry-common.c via
local_daif_restore() or local_daif_inherit(), so the comment is stale.
This logic is likely to chang in future, so it would be best to avoid
referring to those macros specifically.

Update the comment to take this into account, and describe it in terms
of clearing DAIF.D so that it doesn't macro where this logic lives nor
what it is called.

There should be no functional change as a result of this patch.
