Subject: [PATCH v2 10/15] ARM: tegra: jetson-tk1: Correct interrupt trigger type of temperature sensor
Date: Tue,  3 Aug 2021 00:19:42 +0300	[thread overview]
Message-ID: <20210802211947.19715-11-digetx@gmail.com> (raw)
In-Reply-To: <20210802211947.19715-1-digetx@gmail.com>

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.
