Subject: [PATCH 16/17] media: camss: add support for SM8250 camss
The Titan 480 camss found on SM8250 has 6 CSIPHY and 4 VFE/CSID.
CSID is compatible with the Titan 170 CSID, but the Titan 480 CSID are
inside the VFE region (between the "top" and "bus" registers), so a
workaround is added to avoid ioremap failure.
