Subject: [PATCH v2 1/3] dt-bindings: media: camss: qcom,msm8996-camss: Add CAMSS power domain

From: Yassine Oudjana <y.oudjana@...tonmail.com>

Add the CAMSS power domain which is needed for the proper operation of
CAMSS, and add power-domain-names to ease fetching it as well as the other
power domains.
