Subject: [PATCH 1/5] arm64: dts: qcom: x1e80100: Remove interconnect from SCM device
Date: Thu, 12 Mar 2026 21:26:35 +0530	[thread overview]
Message-ID: <20260312-hamoa_pdc-v1-1-760c8593ce50@oss.qualcomm.com> (raw)
In-Reply-To: <20260312-hamoa_pdc-v1-0-760c8593ce50@oss.qualcomm.com>

Interconnect from SCM device are optional and were added to get
additional performance benefit. These nodes however delays the
SCM firmware device probe due to dependency on interconnect and
results in NULL pointer dereference for the users of SCM device
driver APIs, such as PDC driver.

Remove them from the scm device to unblock the user.
