Subject: [PATCH v1 1/1] arm64: dts: imx8mm-var-som: fix touchscreen IRQ trigger
Date: Sun, 18 Oct 2026 19:00:07 +0200 [thread overview]
Message-ID: <20261018170007.38381-1-stefano.r@variscite.com> (raw)
From: Stefano Radaelli <stefano.r@variscite.com>
The touchscreen interrupt is configured as level-high, causing a
pending wakeup that prevents Symphony from entering suspend.
Change the interrupt to falling-edge so the board can suspend
with touchscreen wakeup enabled.
Fixes: 5f67317bd967 ("arm64: dts: imx8mm: correct interrupt flags")
