[PATCH 2/2] arm64: dts: qcom: sdm845-sony-tama: enable modem

[Shujath Mohd]

Enable the modem remoteproc on Sony Xperia TAMA devices and provide
the corresponding MBA and modem firmware.

The modem requires ta-service to be running for proper initialization.

The remoteproc firmware configuration has been verified with the
following firmware running:

  remoteproc0: mba.mbn
  remoteproc1: adsp.mbn
  remoteproc2: cdsp.mbn
  remoteproc3: slpi.mbn

A link to that would be very interesting to people reading this
commit message in N years

I don't quite understand what you're trying to say in this last
paragraph, given the other remoteprocs are standalone and unrelated

Please keep the label references sorted alphabetically

These two properties are there in sdm845.dtsi already

I think patches 1 and 2 make more sense when squashed together,
especially since IPA without modem is not particularly useful

[PATCH v2] arm64: dts: qcom: sdm845-sony-tama: enable modem, SLPI and IPA

[Shujath Mohd]

Enable the modem, SLPI and IPA subsystems on Sony Xperia TAMA
devices and provide the corresponding firmware paths.

The modem requires ta-service for initialization:

Changes in v2:
- Squashed the series into a single patch.
- Removed redundant IPA properties already provided by sdm845.dtsi.
- Sorted the DTS label references alphabetically.
- Documented the ta-service dependency with a link.
