[PATCH v6 0/6] iio: dac: ad5504: bindings, cleanups, locking, and scale fixes

Jonathan Cameron applied patches 2 (sort headers alphabetically) and 4
(introduce local dev pointer) from v3 directly to iio/testing. This
series rebases on top of that state and does not re-send those
patches.

This v6 series addresses one remaining item from the v5 review by
Andy Shevchenko:

* In ad5504_write_dac_powerdown(), move guard(mutex) to after
  kstrtobool() since input parsing does not touch shared state and
  does not need to be under the lock (Andy)

Testing:
No functional change from v5. This only narrows the critical section
in one sysfs write path. Re-verified on ARM64 Raspberry Pi 5 (BCM2712):
powerdown sysfs read/write and powerdown mode switching (20kohm_to_gnd,
three_state) verified on all four channels without errors.

Previous versions:

Thank you to Jonathan Cameron, David Lechner, Andy Shevchenko, Nuno Sá,
