0x3a00 is a reserved register as per the datasheet. The driver currently sets to it 0x01 while the datasheet claims 0x00 to be the default value. On one of the setup based on i.MX8MP platform with IMX335, this register write broke the CSI-2 configuration. Setting 0x3a00 to its default value (i.e. 0x00) fixed the issue. It is not clear from the datasheet what this register write is responsible for but setting it to its default value seems the right thing to do, provided it has been found responsible to break CSI-2 configuration on one of the platform.
