The CAMSS code started from a naive implementation where a fixed define was used as a control in a for(){} loop iterating through RDIs. That model scales badly. An attempt was made with VFE_LINE_NUM_GEN2 and VFE_LINE_NUM_GEN1 to differentiate between SoCs but, the problem with that is "gen1" and "gen2" have no meaning in the silicon. There is no fixed constraint in the silicon between VFE and RDI, it is entirely up to the SoC designers how many VFEs are populated and how many RDIs to associate with each VFE. As an example sdm845 has VFE version 175 and sm8250 VFE version 480. sdm845 has 2 VFEs with 4 RDIs and 1 VFE Lite with 4 RDIs. sm8250 has 2 VFEs with 3 RDIs and 2 VFE Lite with 4 RDIs. Clearly then we need a more granular model to capture the necessary data. The defines have gone away to be replaced with per-SoC data but, we haven't populated the parameter data with the real values. Let's call those values out now msm8916: 1 x VFE 3 x RDI per VFE (not 4) msm8996: 2 x VFE 3 x RDI per VFE (not 4) sdm660: 2 x VFE 3 x RDI per VFE (not 4) sdm845: 2 x VFE 4 x RDI per VFE (not 3) 1 x VFE Lite 4 x RDI per VFE Lite (not 3) sm8250: 2 x VFE 3 x RDI per VFE (not 4) 2 x VFE Lite 4 x RDI per VFE Lite This more complex and correct mapping was not possible prior to passing values via driver data. Now that we have that change in place we can correctly map VFEs to RDIs for each VFE.
