QCS8550 and QCM8550 processor combines powerful computing, extreme edge
AI processing, Wi-Fi 7, and robust video and graphics for a wide range
of use cases for the Internet of Things (IoT). QCS8550 is a QCS version
for QCM8550. Modem RF only in QCM8550 but not in QCS8550.
AIM300 Series is a highly optimized family of modules designed to
support AIoT applications. The module is mounted onto Qualcomm AIoT
carrier board to support verification, evaluation and development. It
integrates QCS8550 SoC, UFS and PMIC chip etc.
AIM stands for Artificial Intelligence Module. AIoT stands for AI IoT.

qcm8550. qcm8550 will be a firmware release series from qualcomm.

We probably need to drop this list, it doesn't surve its purposes.
I am a little confused, do you expect to just remove this "aim300-aiot"
or do you want to introduce a new patch and remove the whole list?

In the review comments for v3 you have been asked to add qcom,sm8550.
But not the qcom,qcm8550. I don't think that there is any need to
mention qcm8550 here.
qcm8550 and sm8550 are different, they have different firmware release.
AIM300 AIoT board depend on qcs8550, qcs8550 is a QCS version for
qcm8550. Modem RF only in qcm8550 but not in qcs8550.
