For RK3399 or > i.MX8MP. For the ISP there is some public docs into imx8mp reference manual at page 5895 chapter: 13.14 Image Signal Processor (ISP) https://www.nxp.com/webapp/Download?colCode=IMX8MPRM https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/evaluation-kit-for-the-i-mx-8m-plus-applications-processor:8MPLUSLPD4-EVK This is not the full docs I think but cover some part of the ISP functionality.
