OPP: Reuse dev_pm_opp_get_freq_indexed()

2025-02-21T12:48:56Z

[ Upstream commit 746de8255076c9924ffa51baad9822adddccb94e ] Reuse dev_pm_opp_get_freq_indexed() from dev_pm_opp_get_freq().

OPP: Add dev_pm_opp_find_freq_exact_indexed()

2025-02-21T12:48:56Z

[ Upstream commit a5893928bb179d67ca1d44a8f66c990480ba541d ] The indexed version of the API is added for other floor and ceil, add the same for exact as well for completeness.

OPP: Introduce dev_pm_opp_get_freq_indexed() API

2025-02-21T12:48:56Z

[ Upstream commit 5f756d03e2c7db63c1df7148d7b1739f29ff1532 ] In the case of devices with multiple clocks, drivers need to specify the frequency index for the OPP framework to get the specific frequency within the required OPP. So let's introduce the dev_pm_opp_get_freq_indexed() API accepting the frequency index as an argument.

OPP: Introduce dev_pm_opp_find_freq_{ceil/floor}_indexed() APIs

2025-02-21T12:48:56Z

[ Upstream commit 142e17c1c2b48e3fb4f024e62ab6dee18f268694 ] In the case of devices with multiple clocks, drivers need to specify the clock index for the OPP framework to find the OPP corresponding to the floor/ceil of the supplied frequency. So let's introduce the two new APIs accepting the clock index as an argument. These APIs use the exising _find_key_ceil() helper by supplying the clock index to it.

OPP: Rearrange entries in pm_opp.h

2025-02-21T12:48:56Z

[ Upstream commit 754833b3194c30dad5af0145e25192a8e29521ab ] Rearrange the helper function declarations / definitions to keep them in order of freq, level and then bw.

OPP: Remove dev{m}_pm_opp_of_add_table_noclk()

2022-07-12T15:05:21Z

Remove the now unused variants and the now unnecessary "getclk" parameter from few routines. Signed-off-by: Viresh Kumar

OPP: Allow multiple clocks for a device

2022-07-12T15:05:20Z

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()

2022-07-08T05:57:50Z

This was added few years back, but the code that was supposed to use it never got merged. Remove the unused helper. Tested-by: Dmitry Osipenko Signed-off-by: Viresh Kumar

OPP: Remove custom OPP helper support

2022-07-08T05:57:50Z

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. Tested-by: Dmitry Osipenko Signed-off-by: Viresh Kumar
