Subject: [PATCH 0/3] Enable CTCU and ETR devices for multiple QCOM
 platforms

The DT‑binding patch adds platform‑specific compatibles for the
CTCU device, and the following Qualcomm platforms are included:
Kaanapali
Pakala(sm8750)
Hamoa
Glymur

Since the base Coresight DT patches for the Kaanapali and Glymur
platforms have not yet been applied, I created DT patches only
for the Pakala and Hamoa platforms. I will submit the Kaanapali
and Glymur patches once their corresponding base Coresight DT patches
are merged.

The Hamoa‑related patches were posted in a separate email, and I
have included them in the current patch series.
