Cristian Ciocaltea 80bd119c7d clk: actions: Fix bisp_factor_table based clocks on Owl S500 SoC
[ Upstream commit a8f1f03caa51aa7a69c671aa87c475034db7d368 ]

The following clocks of the Actions Semi Owl S500 SoC have been defined
to use a shared clock factor table 'bisp_factor_table[]': DE[1-2], VCE,
VDE, BISP, SENSOR[0-1]

There are several issues involved in this approach:

* 'bisp_factor_table[]' describes the configuration of a regular 8-rates
  divider, so its usage is redundant. Additionally, judging by the BISP
  clock context, it is incomplete since it maps only 8 out of 12
  possible entries.

* The clocks mentioned above are not identical in terms of the available
  rates, therefore cannot rely on the same factor table. Specifically,
  BISP and SENSOR* are standard 12-rate dividers so their configuration
  should rely on a proper clock div table, while VCE and VDE require a
  factor table that is a actually a subset of the one needed for DE[1-2]
  clocks.

Let's fix this by implementing the following:

* Add new factor tables 'de_factor_table' and 'hde_factor_table' to
  properly handle DE[1-2], VCE and VDE clocks.

* Add a common div table 'std12rate_div_table' for BISP and SENSOR[0-1]
  clocks converted to OWL_COMP_DIV.

* Drop the now unused 'bisp_factor_table[]'.

Additionally, drop the CLK_IGNORE_UNUSED flag for SENSOR[0-1] since
there is no reason to always keep ON those clocks.

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.
