Umang Jain 14a60786d7 media: imx335: Set reserved register to default value
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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
