Remove the now unused variants and the now unnecessary "getclk"
parameter from few routines.

OPP: Allow multiple clocks for a device

2022-07-12T15:05:20+00:00

This patch adds support to allow multiple clocks for a device.

The design is pretty much similar to how this is done for regulators,
and platforms can supply their own version of the config_clks() callback
if they have multiple clocks for their device. The core manages the
calls via opp_table->config_clks() eventually.

We have kept both "clk" and "clks" fields in the OPP table structure and
the reason is provided as a comment in _opp_set_clknames(). The same
isn't done for "rates" though and we use rates[0] at most of the places
now.

OPP: Remove dev_pm_opp_find_freq_ceil_by_volt()

2022-07-08T05:57:50+00:00

This was added few years back, but the code that was supposed to use it
never got merged. Remove the unused helper.

OPP: Remove custom OPP helper support

2022-07-08T05:57:50+00:00

The only user of the custom helper is migrated to use
dev_pm_opp_set_config_regulators() interface. Remove the now unused
custom OPP helper support.

This cleans up _set_opp() and leaves a single code path to be used by
all users.

OPP: Add dev_pm_opp_get_supplies()

2022-07-08T05:57:49+00:00

We already have an API for getting voltage information for a single
regulator, dev_pm_opp_get_voltage(), but there is nothing available for
multiple regulator case.

This patch adds a new API, dev_pm_opp_get_supplies(), to get all
information related to the supplies for an OPP.

OPP: Add support for config_regulators() helper

2022-07-08T05:57:49+00:00

Extend the dev_pm_opp_set_config() interface to allow adding
config_regulators() helpers. This helper will be called to set the
voltages of the regulators from the regular path in _set_opp(), while we
are trying to change the OPP.

This will eventually replace the custom set_opp() helper.

OPP: Migrate set-prop-name helper API to use set-config helpers

2022-07-08T05:57:49+00:00

Now that we have a central API to handle all OPP table configurations,
migrate the set-prop-name family of helpers to use the new
infrastructure.

The return type and parameter to the APIs change a bit due to this,
update the current users as well in the same commit in order to avoid
breaking builds.

Remove devm_pm_opp_register_set_opp_helper() as it has no users
currently.
