OPP: Provide a simple implementation to configure multiple clocks

2022-06-24T05:23:13+00:00

This provides a simple implementation to configure multiple clocks for a device. Signed-off-by: Viresh Kumar

OPP: Assert clk_count == 1 for single clk helpers

2022-06-24T05:23:13+00:00

Many helpers can be safely called only for devices that have a single clk associated with them. Assert the same for those routines. Signed-off-by: Viresh Kumar

OPP: Add key specific assert() method to key finding helpers

2022-06-24T05:23:13+00:00

The helpers for the clock key, at least, would need to assert that the helpers are called only for single clock case. Prepare for that by adding an argument to the key finding helpers. Signed-off-by: Viresh Kumar

OPP: Allow multiple clocks for a device

2022-06-24T05:22:56+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: Make dev_pm_opp_set_opp() independent of frequency

2022-06-24T00:52:29+00:00

dev_pm_opp_set_opp() can be called for any device, it may or may not have a frequency value associated with it. If a frequency value isn't available, we pass 0 to _set_opp(). Make it optional instead by making _set_opp() accept a pointer instead, as the frequency value is anyway available in the OPP. This makes dev_pm_opp_set_opp() and _set_opp() completely independent of any special key value. Signed-off-by: Viresh Kumar

OPP: Reuse _opp_compare_key() in _opp_add_static_v2()

2022-06-24T00:52:29+00:00

Reuse _opp_compare_key() in _opp_add_static_v2() instead of just comparing frequency while finding suspend frequency. Also add a comment over _opp_compare_key() explaining its return values. Signed-off-by: Viresh Kumar

OPP: Remove rate_not_available parameter to _opp_add()

2022-06-24T00:52:28+00:00

commit 32715be4fe95 ("opp: Fix adding OPP entries in a wrong order if rate is unavailable") removed the only user of this field, get rid of rest of it now. Signed-off-by: Viresh Kumar

OPP: Use consistent names for OPP table instances

2022-06-24T00:52:28+00:00

The OPP table is called "opp_table" at most of the places and "table" at few. Make all of them follow the same naming convention, "opp_table". Signed-off-by: Viresh Kumar

OPP: Use generic key finding helpers for bandwidth key

2022-06-24T00:52:28+00:00

Use the recently added generic key findings helpers to find bandwidth key values. Signed-off-by: Viresh Kumar

OPP: Use generic key finding helpers for level key

2022-06-24T00:52:28+00:00

Use the recently added generic key findings helpers to find level key values. Signed-off-by: Viresh Kumar
