Current code executes only once despite the while loop, so remove the
loop. Also msleep(1) will likely result in a larger sleep, so increase
its value for clarity while keeping the same behaviour.

Convert the da9062 PMIC device tree binding documentation to json-schema.

Document the missing gpio child node for da9062.

While at it, update description with link to product information and
example.

The missing child node with of_compatible defined in MFD_CELL_OF is
causing the below warning message:
da9062-gpio: Failed to locate of_node [id: -1]

So, make all child nodes with of_compatible defined in struct mfd_cell
as required property for da906{1,2} devices.

The "gpio-controller" and "#gpio-cells" properties are defined in the
parent instead of gpio child node as there are existing driver users
based on these parent properties.

Pull more bcachefs updates from Kent Overstreet:
 "Some fixes, Some refactoring, some minor features:

   - Assorted prep work for disk space accounting rewrite

   - BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
     makes our trigger context more explicit

   - A few fixes to avoid excessive transaction restarts on
     multithreaded workloads: fstests (in addition to ktest tests) are
     now checking slowpath counters, and that's shaking out a few bugs

   - Assorted tracepoint improvements

   - Starting to break up bcachefs_format.h and move on disk types so
     they're with the code they belong to; this will make room to start
     documenting the on disk format better.

   - A few minor fixes"
