[PATCH RFC 0/4] net: ipa: add support for Eliza SoC (IPA 5.5)

[PATCH RFC 0/4] net: ipa: add support for Eliza SoC (IPA 5.5)

[Alexander Koskovich]

This series adds support to the IPA driver for the Eliza SoC (IPA 5.5).

Wanted some feedback on how best to handle the difference in the Q6 FNR
counters between Eliza & SM8550/SM8650, since it also changes the memory
layout [1].

I was thinking about something like checking firmware version after
loading IPA firmware and if above X version, use increased FnR counters
but I am not sure what firmware version this was introduced in.

For now I am just doing it with a seperate Eliza compatible but this
feels kind of meh. I'm also not sure if it's possible there's some Eliza
variant out there that actually has firmware that is too old, and then
68 for FnR counters is too much.

I also wanted some clarification on the general need to pass hw filter
stats info, downstream this is marked as "optional", but seems very
much needed for Eliza.

Is this actually optional and there is just some other misconfiguration
or is firmware broken? Hard to debug what modem wants since system does
a complete halt shortly after starting IPA if I don't pass this.

[PATCH RFC 1/4] dt-bindings: net: qcom,ipa: document Eliza compatible

[Alexander Koskovich]

Document the IPA on the Eliza Platform which uses version 5.5.1,
which is a minor revision of v5.5 found on SM8550, thus we can
use the SM8550 bindings as fallback since it shares the same
register mappings.

[PATCH RFC 3/4] net: ipa: add new QMI request for HW filter stats info

[Alexander Koskovich]

Some IPA firmware versions on IPA 5.5 require ipa_filter_stats_info in
the init_modem_driver QMI request. For example on Eliza, if this is not
passed then shortly after IPA init the system will halt and reboot
shortly after.

Downstream this is marked as optional but does not seem to be the case
on newer IPA firmware versions.

[PATCH RFC 4/4] net: ipa: add Eliza configuration data

[Alexander Koskovich]

Add the configuration data required for Eliza, which uses IPA v5.5. The
difference over other platforms that use IPA 5.5 is the Q6 FnR counters
have been increased on the firmware version it uses, which results in a
different memory layout.

FWIW:

8650 -> v5.5.1

eliza
8750
and a couple others
-> 5.5.2
