The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. "i2c-parent" is
the former and needs to constrain each entry to a single phandle value.

Convert AMD (Xilinx) sd-fec bindings to yaml format, so it can validate
dt-entries as well as any future additions to yaml.
Change in clocks is due to IP is itself configurable and
only the first two clocks are in all combinations. The last
6 clocks can be present in some of them. It means order is
not really fixed and any combination is possible.
Interrupt may or may not be present.
The documentation for sd-fec bindings is now YAML, so update the
MAINTAINERS file.
Update the link to the new yaml file in xilinx_sdfec.rst.

Convert the generic fpga region DT binding to json-schema.
There are some differences compare to txt version.
1. DT overlay can't be described in example that's why directly include
information from overlay to node which was referenced. It is visible in
example with /* DT Overlay contains: &... */

2. All example have been rewritten to be simpler and describe only full
reconfiguration and partial reconfiguration with one bridge.
Completely drop the case where fpga region can inside partial
reconfiguration region which is already described in description

3. Fixed some typos in descriptions compare to txt version but most of it
is just c&p from txt file.

There are cases where an unavailable port is not an error, making this
error message a false-positive. Since commit d56de8c9 ("usb: typec:
tcpm: try to get role switch from tcpc fwnode") the role switch is tried
on the port dev first and tcpc fwnode afterwards. If using the latter
bindings getting from port dev fails every time. The kernel log is flooded
with the messages like:
 OF: graph: no port node found in /soc@0/bus@42000000/i2c@42530000/usb-typec@50
Silence this message by making it a debug message.

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"

bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.

And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.

Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.
