* clk: meson: add sclk-ws driverJerome Brunet2020-08-171-0/+56
| | | | | | | | | | | | | | | This is yet another simple but odd driver for the audio block of the g12a and sm1 SoC families. For TDMOUT's sclk to be properly inverted, bit 29 of AUDIO_CLK_TDMOUT_x_CTRL should be the inverse of bit 28. IOW bit28 == !bit29 at all times This setting is automatically applied on axg and the manual setting was added on g12a.

* clk: let init callback return an error codeJerome Brunet2019-12-231-1/+3
| | | | | | | | | | | 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 dependenciesJerome Brunet2019-02-021-5/+70
| | | | | | | | | | | | | | | | | | | | | | | 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.
