Subject: [PATCH v1 07/13] ARM: tegra: apalis: Correct interrupt trigger type of temperature sensor
Date: Mon, 12 Jul 2021 02:43:57 +0300	[thread overview]
Message-ID: <20210711234403.24691-8-digetx@gmail.com> (raw)
In-Reply-To: <20210711234403.24691-1-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.
