Subject: [PATCH 7/7] media: qcom: camss: Add Waipio CAMSS support
Date: Fri, 23 Oct 2026 19:30:57 +0300	[thread overview]
Message-ID: <20261023163057.775917-8-vz@kernel.org> (raw)
In-Reply-To: <20261023163057.775917-1-vz@kernel.org>

Add support of the camera subsystem (CAMSS) found on Qualcomm Waipio SoC.

The CAMSS IP on Waipio contains:
* three CSID and two CSID lite, which are supported by CSID 680,
* three VFE and two VFE lite blocks, which are supported by VFE 680,
* three CSI test pattern generators, which are supported by TPG Gen1.

Qualcomm Waipio CSIPHYs are supported by the CSI2 PHY driver only.
