Ok, I agree. These can be use case controls instead of DT settings.

They were useful for some algorithm debug at a customer site. They aren't used for production.

Agreed, we'll put this in DAPM.

+Optional properties:

Would it be best to use SND_SOC_DAIFMT_CONT/GATED for these? Unless I have misunderstood their purpose, although presently that doesn't give you individual control over sclk and lrclk.

cirrus,vpbr-wait = <0x01>;
cirrus,vpbr-rel-rate = <0x05>;

cirrus,irq-gpio-select = <0x01>;
cirrus,irq-output-enable = <0x01>;

This block is not documented in the rest of the document and looks like things that should really be controlled through other means. Presuming this is legacy and just needs removed?

Seems they are used by the driver so I guess best to document them as a first step and we can review them from there.
Also looks like documentation is also missing for:
dcm-mode-enable boost-ind-nanohenry

Simple on/off conttrols should be _SINGLE controls with Switch at the end of their name. It's not super clear why this is in DAPM as a widget at all, the routing around it is:
+ {"BOOST Mux", "On", "Channel Mux"}, + {"CLASS H", NULL, "BOOST Mux"},
which is a bit perplexing. Possibly this should be handled in the event for the main amplifier?

These are just constants, why write out the operations?

This unconditionally reports that it handled the interrupt, even if it didn't. This will stop the interrupt core handling for faulty interrupt lines working and will disrupt any support that gets added for handling shared threaded interrupts.

This doesn't handle -EPROBE_DEFER.

Your allocating an array that is much larger than you need here. This array will have an entry for all possible register addresses on the device, whereas only a very small subset of those addresses have defaults infact most of them arn't even registers.

These two completions are unused.

Yet it is only used locally in this function.

Nitpicking: Since both paths add 4 you could initialise fs1_val and fs2_val to 4, then use += would avoid the line wraps for the + 4's here.

This null check shouldn't be needed now since:

extclk_freq doesn't appear to be used at all, is there an expectation it will be in the future?
- cs35l36->prev_clksrc = cs35l36->clksrc;
Should this be stored in cs35l36_private, given it is only used locally in this function?

Seems clksrc is also only used locally, is there some future work expected on the clocking?

Would it be simpler just to return a pointer to the cs35l36_pll_sysclk_config structure?

Nitpick: This is already checked before you call the function, so I would be inclined to drop it but if doing it here it would probably be better to invert the logic and do:
if (cs35l36->rev_id != CS35L36_REV_B0) return 0;
- switch (cs35l36->rev_id) {
- case CS35L36_REV_A0:

cs35l36_reva0_errata_patch,
ARRAY_SIZE(cs35l36_reva0_errata_patch));
if (ret < 0) {
dev_err(dev, "Failed to apply A0 errata patch %d\n",
ret);
goto err;
}
ret = regmap_register_patch(cs35l36->regmap,
cs35l36_pac_int_patch,
ARRAY_SIZE(cs35l36_pac_int_patch));
if (ret < 0) {
dev_err(dev, "Failed to apply A0PAC errata patch %d\n",
ret);
goto err;
}
Is this really what you want, having two calls to remap_register_patch will apply the settings from both here, but only the second of those calls would be reapplied on cache_sync later. Now I guess you don't have any cache_syncs so it won't cause a problem now but feels like it has the potential to cause confusion down the road.

Nitpick probably fire this up on the same line as the ONESHOT.
