For K3 devices the clock fed into the RNG module is shared with the rest
of the Crypto module, it is not dedicated to the RNG module and cannot be
controlled by the RNG driver. The driver does not require this clock to
always be defined and the DT binding should not force it either.

Remove this so we can start dropping out the clock properties as needed.

New pr_err(), a copy of preceeding pr_debug(), faciliates debugging.

This change was inspired by a long lasting debugging of the
octeon_irq_init_ciu() which fails completely silently and leaves the
interrupt controller half-way configured which in turn had very non-obvious
effects.

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate
dt-entries correctly and any future additions can go into yaml format.

Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and
qcom,smd-channels missing properties to make sure dtbs_check doesn't fail
right off the bat. Correct the name of the parent node in the example from
smd-edge to glink-edge.

Since now the qcom,fastrpc bindings document is yaml, update the
reference to it in qcom,glink-edge and also use $ref.

Also update the MAINTAINERS file to point to the yaml version.

Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.
