Subject: [PATCH v1] arm64: dts: imx8-ss-img: Avoid gpio0_mipi_csi GPIOs being deferred
Date: Tue, 14 Oct 2025 09:56:43 -0300 [thread overview]
Message-ID: <20251014-imx8-gpio-csi-deferred-probe-v1-1-62dd1b949731@toradex.com> (raw)
From: João Paulo Gonçalves <joao.goncalves@toradex.com>
The gpio0_mipi_csi DT nodes are enabled by default, but they are
dependent on the irqsteer_csi nodes, which are not enabled. This causes
the gpio0_mipi_csi GPIOs to be probe deferred. Since these GPIOs can be
used independently of the CSI controller, enable irqsteer_csi by default
too to prevent them from being deferred and to ensure they work out of
the box.
Fixes: 2217f8243714 ("arm64: dts: imx8: add capture controller for i.MX8's img subsystem")
