Jacopo Mondi 61da76beef media: v4l2: i2c: ov7670: Fix PLL bypass register values 
The following commits:
commit f6dd927f34 ("[media] media: ov7670: calculate framerate properly for ov7675")
commit 04ee6d9204 ("[media] media: ov7670: add possibility to bypass pll for ov7675")
introduced the ability to bypass PLL multiplier and use input clock (xvclk)
as pixel clock output frequency for ov7675 sensor.

PLL is bypassed using register DBLV[7:6], according to ov7670 and ov7675
sensor manuals. Macros used to set DBLV register seem wrong in the
driver, as their values do not match what reported in the datasheet.

Fix by changing DBLV_* macros to use bits [7:6] and set bits [3:0] to
default 0x0a reserved value (according to datasheets).

While at there, remove a write to DBLV register in
"ov7675_set_framerate()" that over-writes the previous one to the same
register that takes "info->pll_bypass" flag into account instead of setting PLL
multiplier to 4x unconditionally.

And, while at there, since "info->pll_bypass" is only used in
set/get_framerate() functions used by ov7675 only, it is not necessary
to check for the device id at probe time to make sure that when using
ov7670 "info->pll_bypass" is set to false.

Fixes: f6dd927f34 ("[media] media: ov7670: calculate framerate properly for ov7675")

README 

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.
