I think Iris does those itself see:

                 iris: video-codec at aa00000 {
                         compatible = "qcom,x1e80100-iris", 
"qcom,sm8550-iris";

                         reg = <0 0x0aa00000 0 0xf0000>;
                         interrupts = <GIC_SPI 174 IRQ_TYPE_LEVEL_HIGH>;

                         power-domains = <&videocc VIDEO_CC_MVS0C_GDSC>,
                                         <&videocc VIDEO_CC_MVS0_GDSC>,
                                         <&rpmhpd RPMHPD_MXC>,
                                         <&rpmhpd RPMHPD_MMCX>;
                         power-domain-names = "venus",
                                              "vcodec0",
                                              "mxc",
                                              "mmcx";

Still not getting an especially clear picture on what _levels_ you are 
proposing here for MXA - here are the three opps we have for the PHY.

Sorry I don't get how turbo is coming into this ..

+    csiphy_opp_table: opp-table-csiphy {
+        compatible = "operating-points-v2";
+
+        opp-300000000 {
+            opp-hz = /bits/ 64 <300000000>;
+            required-opps = <&rpmhpd_opp_low_svs_d1>;
+        };
+
+        opp-400000000 {
+            opp-hz = /bits/ 64 <400000000>;
+            required-opps = <&rpmhpd_opp_low_svs>;
+        };
+
+        opp-480000000 {
+            opp-hz = /bits/ 64 <480000000>;
+            required-opps = <&rpmhpd_opp_low_svs>;
+        };
+    };
