clk: meson: sclk-div: switch from .round_rate to .determine_rate

2023-01-13T14:14:12Z

clk_ops.round_rate will be removed at some point. It's replacement is .determine_rate. Switch sclk-div over to use .determine_rate.

clk: let init callback return an error code

2019-12-24T02:53:13Z

If the init callback is allowed to request resources, it needs a return value to report the outcome of such a request.

clk: meson: rework and clean drivers dependencies

2019-02-02T16:43:32Z

Initially, the meson clock directory only hosted 2 controllers drivers, for meson8 and gxbb. At the time, both used the same set of clock drivers so managing the dependencies was not a big concern. Since this ancient time, entropy did its job, controllers with different requirement and specific clock drivers have been added. Unfortunately, we did not do a great job at managing the dependencies between the controllers and the different clock drivers. Some drivers, such as clk-phase or vid-pll-div, are compiled even if they are useless on the target (meson8). As we are adding new controllers, we need to be able to pick a driver w/o pulling the whole thing. The patch aims to clean things up by: * providing a dedicated CONFIG_ for each clock drivers * allowing clock drivers to be compiled as a modules, if possible * stating explicitly which drivers are required by each controller.

clk: meson: add axg audio sclk divider driver

2018-07-09T11:48:25Z

Add a driver to control the clock divider found in the sample clock generator of the axg audio clock controller. The sclk divider accumulates specific features which make the generic divider unsuitable to control it: - zero based divider (div = val + 1), but zero value gates the clock, so minimum divider value is 2. - lrclk variant may adjust the duty cycle depending the divider value and the 'hi' value.
