Subject: [PATCH 1/5] dt-bindings: thermal: tsens: Add ipq8074 compatible
Date:   Sat, 30 Apr 2022 22:50:57 +0200
Message-Id: <20220430205101.459782-1-robimarko@gmail.com>

Qualcomm IPQ8074 has tsens v2.3.0 block, though unlike existing v2 IP it
only uses one IRQ, so tsens v2 compatible cannot be used as the fallback.

We also have to make sure that correct interrupts are set according to
compatibles, so populate interrupt information per compatibles.
