[0/8] reset: amlogic: move audio reset drivers out of CCF

Message

Jerome Brunet July 10, 2024, 4:25 p.m. UTC

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 patchset moves the reset driver of audio clock controller of 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.

Change since RFC [2]:
 * Move the aux registration helper out of clock too.

  reset: amlogic: convert driver to regmap
  reset: amlogic: add driver parameters
  reset: amlogic: split the device and platform probe
  reset: amlogic: use reset number instead of register count
  reset: amlogic: add reset status support
  reset: amlogic: add toggle reset support
  reset: amlogic: add auxiliary reset driver support
  clk: amlogic: axg-audio: use the auxiliary reset driver

Jerome, I have tested the series on SM1 SoC (Amlogic AC200 ref board).
As far as I can tell, it works as it should
