Given that the 2nd controller is mostly about VAD (PDM is there only to feed it) and that it is just a name, I'd prefer something like a1_audio_vad. > + > +static int a1_register_clk(struct platform_device *pdev, struct regmap *map, > + struct clk_hw *hw) > +{ > + struct clk_regmap *clk = container_of(hw, struct clk_regmap, hw); > + > + if (!hw) > + return 0; > + > + clk->map = map; > + > + return devm_clk_hw_register(&pdev->dev, hw); > +} Why do you have to do that and cannot do it like the rest of the modules ? > + > +struct a1_audio_data { > + struct meson_clk_hw_data hw_clks; > + int core_clkid; > + const char *core_fwname; > + unsigned int reset_offset; > + unsigned int reset_num; > +}; > + > +static const struct regmap_config a1_audio_regmap_cfg = { > + .reg_bits = 32, > + .val_bits = 32, > + .reg_stride = 4, > +}; > + > +static int a1_audio_clkc_probe(struct platform_device *pdev) > +{ > + const struct a1_audio_data *data; > + struct regmap *map; > + void __iomem *base; > + struct clk *clk; > + unsigned int i; > + int ret; > + > + data = of_device_get_match_data(&pdev->dev); > + if (!data) > + return -EINVAL; > + > + if (data->core_fwname) { That is really over-complicated for what it does .... > + clk = devm_clk_get_enabled(&pdev->dev, data->core_fwname); It does not make a lot of sense that one of the 2 controllers as 2nd pclk. You should consider using the AUD2_CLKID_AUDIOTOP as a parent of audio gates instead.

Just make an external function for the register, use it for axg, a1, a1-vad, then make one file for each controller.

This controller provides clocks and reset functionality for audio peripherals on Amlogic A1 SoC family. The driver is almost identical to 'axg-audio', however it would be better to keep it separate due to following reasons: - significant amount of bits has another definition. I will bring there a mess of new defines with A1_ suffixes. - registers of this controller are located in two separate regions. It will give a lot of complications for 'axg-audio' to support this.
