The SYSTEM_CTRL0 register in ov5645 is almost similar to ov5640. But the hard reset control is mandatory for the ov5645 device, so there is no need for soft reset in the driver. Add a 1msec delay for the software power up (OV5645_SYSTEM_CTRL0_START) register in ov5645_global_init_setting. Without this delay sometimes the image is not captured at all when the i2c frequency is 400kHz. The changes are fixing both the greenish issue and image capture at 400kHz i2c frequency on Renesas RZ/G2L SMARC EVK platforms.

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.
