This driver came out from reverse engineering of so called "userspace drivers" from Sony Xperia smartphones. I tried to document all of my findings and giving a sense to the registers as much as possible, but that was only partially possible and resembles some names from the IMX219 public datasheet, even though the addresses are basically completely different. This camera sensor driver was tested with all the resolutions declared in it on two phones: Sony Xperia XA2 and XA2 Ultra, on a SDM630 SoC (camss patches for this SoC will come in a later series) and is working great.
