Subject: [PATCH v2 net-next 0/4] net: ipa: remove a build dependency

Rob, for some reason I can't find in my mailbox your report that
the binding caused a problem.  I only discovered it when looking
into why the series was not accepted yet.

Version 2 includes <.../arm-gic.h> rather than <.../irq.h> in the
example section of the binding, to ensure GIC_SPI is defined.
I verified this passes "make dt_bindings_check".

The rest of the series is unchanged.  Below is the original cover
letter.

---

Unlike the original (temporary) IPA notification mechanism, the
generic remoteproc SSR notification code does not require the IPA
driver to maintain a pointer to the modem subsystem remoteproc
structure.

The IPA driver was converted to use the newer SSR notifiers, but the
specification and use of a phandle for the modem subsystem was never
removed.

This series removes the lookup of the remoteproc pointer, and that
removes the need for the modem DT property.  It also removes the
reference to the "modem-remoteproc" property from the DT binding,
and from the DT files that specified them.

David/Jakub, please take these all through net-next if they are
acceptable to you, once Rob has acked the binding and DT patches.

Thanks.
