Subject: [PATCH v5 7/7] media: qcom: camss: Flag CSID-lites to support more
CSIDs
From: Matti Lehtimäki <matti.lehtimaki@...il.com>
Some platforms such as SC7280 have 3 CSIDs and 2 CSID-lites but current
code has hardcoded 2 as the maximum number of CSIDs. Remove the hardcoded
maximum number of VFEs to handle all possible combinations of CSIDs and
CSID-lites.
