It is fsl,mxc-mipi-csi2. And they wrote a second driver used on other SoCs (i.MX8MQ) that, according to its first commit message, should eventually be merged with the first driver. Its compatible string is simply fsl,mxc-mipi-csi2_yav. That driver accesses just a single GPR register which contains a subset of the bits found in the CSR registers of the i.MX8QXP.
