[PATCH v1 06/13] ARM: tegra: nyan: Correct interrupt trigger type of temperature sensor
From: Dmitry Osipenko
Date: Sun Jul 11 2021 - 19:44:57 EST
The LM90 temperature sensor should use edge-triggered interrupt because
LM90 hardware doesn't deassert interrupt line until temperature is back
to normal state, which results in interrupt storm. Correct the interrupt
trigger type.
