Does the article seem AI-written/assisted to anyone else?

Some parts that stood out to me: > A phone camera is not a single device. On Qualcomm SoCs, the capture path is a chain: > The bus register base moved from 0xa00 to 0x1800, and encapsulating that offset shift accounted for most of the work. > It gated the AHB register bus used by the whole camera complex, including the CCI. Without it, register accesses silently returned zero. > With the wrong numbering, CSIPHY programmed a lane mask with lane 0 missing, and the PHY never locked. > This was the main bug. Frames arrived at the right rate and size, and buf_done fired, but every pixel was zero. [...] The data path delivered frame timing, but not pixel data. > Changing the register value from PLAIN64 (0xa) to 0x0 turned the all-zero frames into real images: the maximum pixel value was 255, the full colour-bar pattern appeared, and the violations stopped.

Sorry if not, but it seems like so much uses AI nowadays.

have fairphone looked into supporting GrapheneOS? what exactly is missing there other than "it's not Pixel"?
