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.

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.
