commit 52abe6cc ("ASoC: topology: fix oops/use-after-free case with dai driver") fixups remove_dai() error, but it is using list_for_each_entry() for component->dai_list. We already have for_each_component_dais() macro for it. Let's use exising method. Signed-off-by:

We can find specified name component via snd_soc_rtdcom_lookup(). But, it is not enough under multi CPU/Codec/Platform, because many components which have same driver name might be connected to same rtd. Not using this function as much as possible is best solution, but some drivers are already deeply depended to it. We can expand this function, for example having "num" which specifies found order at parameter, etc (In such case, it need to have fixed probing order). Or, use different driver name in such component, etc. We will have such issue if multi CPU/Codec/Platform were supported. To indicate it, this patch adds NOTE to this function. Signed-off-by:

It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. soc-core.c is using device_unregiser(), but there is no its paired device_regiser(). We can find its code at soc_post_component_init() which is using device_initialize() and device_add(). Here, device_initialize() + device_add() = device_register(). -- linux/drivers/base/core.c -- int device_register(struct device *dev) { device_initialize(dev); return device_add(dev); } device_initialize() is doing each dev member's initialization only, not related to device parent/release/groups. Thus, we can postpone it. let's use device_register() instead of device_initialize()/device_add(). Signed-off-by: -

In addition to the I2S format, the controller also supports the DSP_* formats. This requires some extra care on the LRCK period calculation, since the controller, with the PCM formats, require that the value set is no longer the periods of LRCK for a single channel, but for all of them. Let's add the code to deal with this, and support the DSP_A and DSP_B formats. Signed-off-by:

The LRCK period field in the FMT0 register holds the number of LRCK period for one channel in I2S mode. This has been hardcoded to 32, while it really should be the physical width of the format, which creates an improper clock when using a 16bit format, with the i2s controller as LRCK master.

The clock dividers function has been using the word size to compute the clock rate at which it's supposed to be running, but the proper formula would be to use the physical width and / or slot width in TDM. It doesn't make any difference at the moment since all the formats supported have the same sample width and physical width, but it's not going to last forever.

This controller supports capture and playback running at the same time, with the limitation that both capture and playback must be configured the same way (sample rate, sample format, number of channels, etc). For this, we have to assure that the configuration registers look the same when capture and playback are initiated. This patch fixes a bug in which the controller is in master mode and the hw_params() callback fails for the second audio stream. The fail occurs because the divisors are calculated after comparing the configuration registers for capture and playback. The fix consists in calculating the divisors before comparing the configuration registers. BCLK and LRC are then configured and started only if the controller is not already running.

The LRCK polarity "normal" polarity in the I2S/TDM specs and in the Allwinner datasheet are not the same.

The LRCK and BCLK polarity offsets on newer SoCs has been changed, yet the driver didn't take it into account for all of them. This was taken into account for the H3, but not the A83t. This was handled using a reg_field for the H3. However, the value in that field will not be the same, so reg_field is not adapted in that case. Let's change for proper calls with the regular values.

From: Marcus Cooper <codekipper@gmail.com> The clock division dividers have changed between the older (A10/A31) and newer (H3, A64, etc) SoCs. While this was addressed through an offset on some SoCs, it was missing some dividers as well, so the support wasn't perfect. Let's introduce a pointer in the quirk structure for the divider calculation functions to use so we can have the proper range now. Signed-off-by:

On the first generation of Allwinner SoCs (A10-A31), the i2s controller was using the MCLK as BCLK parent. However, this changed since the introduction of the A83t and BCLK now uses the module clock as its parent. Let's introduce a hook to get the parent rate and use that in our divider calculations.

The two main generations of our I2S controller require a slightly different format configuration, mostly because of a quite different register layout and some additional registers being needed on the newer generation. This used to be controlled through a bunch of booleans, however this proved to be quite impractical, especially since a bunch of SoCs forgot to set those parameters and therefore were broken from that point of view.

The MCLK divider calculation is currently computing the ideal divider using the oversample rate, the sample rate and the parent rate. However, since we have access to the frequency is supposed to be running at already, and as it turns out we're using it to compute the oversample rate, we can just use the ratio between the parent rate and the MCLK rate to simplify a bit the formula.

The BCLK divider should be calculated using the parameters that actually make the BCLK rate: the number of channels, the sampling rate and the sample width. We've been using the oversample_rate previously because in the former SoCs, the BCLK's parent is MCLK, which in turn is being used to generate the oversample rate, so we end up with something like this: oversample = mclk_rate / sampling_rate bclk_div = oversample / word_size / channels So, bclk_div = mclk_rate / sampling_rate / word_size / channels. And this is actually better, since the oversampling ratio only plays a role because the MCLK is its parent, not because of what BCLK is supposed to be. Furthermore, that assumption of MCLK being the parent has been broken on newer SoCs, so let's use the proper formula, and have the parent rate as an argument.
