net: ipa: Grab IMEM slice base/size from DTS

2026-03-04T01:22:14+00:00

This is a detail that differ per chip, and not per IPA version (and
there are cases of the same IPA versions being implemented across very
very very different SoCs).

This region isn't actually used by the driver, but we most definitely
want to iommu-map it, so that IPA can poke at the data within.

It can't vary, stop storing the same magic number everywhere.

net: ipa: sort all includes

2024-04-18T11:01:05+00:00

Establish the rule that header files are always included in sorted
(POSIX local) order.  Standard and private headers are separated by
a blank line.

Similarly, sort all forward-declarations for structures.

net: ipa: don't assume 8 modem routing table entries

2022-10-27T11:38:13+00:00

Currently all platforms are assumed allot 8 routing table entries
for use by the modem.  Instead, add a new configuration data entry
that defines the number of modem routing table entries, and record
that in the IPA structure.

net: ipa: update comments

2022-10-03T23:49:05+00:00

This patch just updates comments throughout the IPA code.

Transaction state is now tracked using indexes into an array rather
than linked lists, and a few comments refer to the "old way" of
doing things.  The description of how transactions are used was
changed to refer to "operations" rather than "commands", to
(hopefully) remove a possible ambiguity.

IPA register offsets and fields are now handled differently as well,
and the register documentation is updated to better describe the
code.

A few minor updates to comments were made (e.g., adding a missing
word, fixing a typo or punctuation, etc.).

Finally, the local macro atomic_dec_not_zero() is no longer used, so
it is deleted.
