The dts for the CoreTile Express A15x2 A7x3 (TC2) only describes the

Now that we have a mechanism for describing disparate PMUs and their
interrupts in device tree, this patch makes use of these to describe the
PMUs for all CPUs in the system. For consistency, the existing A15 PMU
interrupt-affinity property is reflowed across two lines.

This reverts commit 3d76be5b.

The latest revision of Beaglebone Black does not support RTC-only mode.

To avoid potential hardware damage, RTC-only mode was disabled by
default by commit 7a6cb0ab ("ARM: dts: am335x-boneblack: disable
RTC-only sleep to avoid hardware damage").

Unfortunately, an incorrect fix had already been applied, which instead
of just disabling RTC-only mode, prevents the Beaglebone from powering
down at all.

Revert this patch to fix the power-off regression.

Simplify the power request code by passing an "on" flag, and picking the
right status bit and register offset in the innermost function, based on
this flag.
This allows to remove the rcar_sysc_pwr_{off,on}() helper functions, and
the function pointer through which they were called.

Make sr_bit and reg_offs unsigned while we're at it.

rcar_sysc_update() loops (with interrupts disabled and while holding a
spinlock) until submitting a power shutoff or resume request fails, or
until the submitted request was accepted.
If none of these conditions becomes true, this forms an infinite loop.

Put a limit on the maximum number of loop iterations, and add a small
delay to each iteration, to fix this.

Shrink the individual fields in struct rcar_sysc_ch, as unsigned long or
int is overkill:
  - chan_offs contains a register offset relative to a base value
    (< 512),
  - chan_bit and isr_bit contain bit indices (0-31).

This reduces the size of each instance from 3 (4 on 64-bit) 32-bit words
to 1 32-bit word.
