Hi all, This patch series mainly adds a common driver [5][6] for the top block of the MediaTek audio subsystem, which includes clock part and audio components. This is a minimal driver that manages shared resources like shared registers, and expose a regmap to its sub-nodes. It was tested on the bananapi-r2 and the MT2701 EVB. Also, this driver can be reused by other subsystems (e.g. MMSYS, ETHSYS) in future patch. Patch[1]-[4]: rework for audio enable/disable sequences and update some part of code to make them more generic. Patch[7]~[12]: modify both drivers, audio and clock to adapt the new subsystem.
