Subject: [PATCH v2 1/4] ACPI: scan: Honor ACPI _DEP dependency for NVL CVS
Date: Sat,  4 Jul 2026 22:48:52 +0530	[thread overview]
Message-ID: <20260704171855.1462214-2-arun.t@intel.com> (raw)
In-Reply-To: <20260704171855.1462214-1-arun.t@intel.com>

Add INTC10FA to the ACPI dependency honor list so the CVS driver is
loaded before dependent camera devices are probed on NVL platforms.

This matches the camera dependency handling already used for IVSC-based
platforms and ensures the camera streaming path is initialized before
sensor access or pipeline setup depends on it.
