@0xB0D The complexity is that we have a couple of different versions of IMX519 driver already from the Arducam 16MP camera, as well as an expectation that as this sensor should be CCS compatible, it should run with the already upstream CCS driver.
One thing that /would/ help is if someone can find the full register programming manual for the IMX519 which we have not been able to obtain.
On SDM845 (I would guess this might indicate someone is looking at perhaps the OP6 here) there are a couple of small integration issues for the DT and regulators as well. Anyway - My hope is to work through this and get the SoftISP running on OP6 (with the IMX519) during FOSDEM.
