This patchset follows the discussion about having reset driver in the clock tree [1]. Ideally those should reside in the reset part of tree. Also the code of the amlogic reset driver is very similar between the 2 trees and could use the same driver code. This patcheset alignes the reset drivers present in the reset and clock then adds support for the reset driver of audio clock controller found in the g12 and sm1 SoC family to the reset tree, using the auxiliary bus. The infrastructure put in place is meant to be generic enough so we may eventually also move the reset drivers in the meson8b and aoclk clock controllers. This was tested on sm1 vim3l and gxl aml-s905x-cc. Changes since v4 [6]: * Fix Kconfig depends and select as reported by Philipp and and 0-day robot. Changes since v3 [5]: * Drop pltf/platform as suggested Changes since v2 [4]: * Fix undefined read access of the reset register * Fix Kconfig symbol description Changes since v1 [3]: * Fixes formatting errors reported by Stephen. * Changed parameters type to unsigned * Fix usage of ops passed as parameters, previously ignored. * Return 0 instead of an error if reset support is absent to properly decouple from the clock and have a weak dependency * Split the platform and auxiliary modules in 2 distinct modules to fix the COMPILE_TEST error reported by ktest robot. Change since RFC [2]: * Move the aux registration helper out of clock too.
