rsnd driver sometimes want to know which address is used when debugging. But it will indicate "(____ptrval____)" if it used "%p" on dev_dbg(). Let's use "%pa" or "%px" for it. Signed-off-by:

Larger CODECs may contain many several hundred widgets and which set of parameters is selected only needs to be recorded on a per DAI basis. As such move the selected CODEC to CODEC link params to be stored in the runtime rather than the DAPM widget, to save some memory. Signed-off-by:

Currently multi-CODEC is not supported on CODEC to CODEC links. There are common applications where this would be useful, such as connecting two mono amplifiers to an audio CODEC. Adding support simply requires an update of snd_soc_dai_link_event to loop over the attached CODEC DAIs. Signed-off-by:

Currently, snd_soc_dapm_connect_dai_link_widgets connects up the routes representing normal DAIs, however CODEC to CODEC links are hooked up through separate infrastructure in soc_link_dai_widgets. Improve the consistency of the code by using snd_soc_dapm_connect_dai_link for both types of DAIs. Signed-off-by:

Currently DAPM has a lot of similar code to handle errors from snd_soc_dapm_new_control_unlocked, and much of this code does not really accurately reflect what the function returns. Firstly, most places will check for a return value of -EPROBE_DEFER and silence any error messages in that case. The one notable exception here being dapm_kcontrol_data_alloc which does currently print any error messages in the case of snd_soc_dapm_new_control_unlocked returning NULL or an error. Additionally the error prints being silenced in these case are redundant as snd_soc_dapm_new_control_unlocked can only return -EPROBE_DEFER or NULL when failing. Secondly, most places will treat a return value of NULL as an -ENOMEM. This is not correct either since any error except EPROBE_DEFER will cause a return value of NULL from snd_soc_dapm_new_control_unlocked. Centralise this handling and the error messages within snd_soc_dapm_new_control_unlocked and update the callers to simply check IS_ERR and return. Note that this update is slightly simpler in the case of dapm_kcontrol_data_alloc where that is fairly close to the handling that was already in place. Signed-off-by:

When dapm_power_widgets() is called, the dapm_pre_sequence_async() and dapm_post_sequence_async() functions are scheduled for all DAPM contexts (apart from the card DAPM context) regardless of whether the DAPM context is already in the desired state. The overhead of this is not insignificant and the more DAPM contexts there are the more overhead there is. For example, on the Tegra124 Jetson TK1, when profiling the time taken to execute the dapm_power_widgets() the following times were observed. Times for function dapm_power_widgets() are (us): Min 23, Ave 190, Max 434, Count 39 Here 'Count' is the number of times that dapm_power_widgets() has been called. Please note that the above time were measured using ktime_get() to log the time on entry and exit from dapm_power_widgets(). So it should be noted that these times may not be purely the time take to execute this function if it is preempted. However, after applying this patch and measuring the time taken to execute dapm_power_widgets() again a significant improvement is seen as shown below. Times for function dapm_power_widgets() are (us): Min 4, Ave 16, Max 82, Count 39 Therefore, optimise the dapm_power_widgets() function by only scheduling the dapm_pre/post_sequence_async() work if the DAPM context is not in the desired state.

Main purpose of .nolock_start is we need to call some function without spinlock. OTOH we have .prepare which main purpose is called under atomic context. Then, it is called without spinlock. In summary, our main callback init/quit, and start/stop are called under "atomic context and with spinlock". And some function need to be called under "non-atomic context or without spinlock". Let's merge .nolock_start and prepare to be more clear code. Then, let's rename nolock_stop to cleanup Signed-off-by:

Currently ssiu's .init is only called once during audio stream. But SSIU with different BUSIF, shall be initialized each time, even they are used in the same audio stream. This patch introduces ssiu_status for BUSIF0 to BUSIF7 in rsnd_ssiu, to make sure same .init for different BUSIF can always be executed. To avoid the first stopped stream to stop the whole SSIU, which may still has other BUSIF instance running, use usrcnt to count the usage of SSIU, only the last user of SSIU can stop the whole SSIU.

The number of channel handled by SSI maybe differs from the one set in hw_params, currently SSI checks hw_params's channel number, and constrains to use same channel number, when it is being used by multiple clients. This patch corrects to check runtime channel number rather than channel number set in hw_params. Signed-off-by:

Clocking operations clk_get/set_rate, are non-atomic, they shouldn't be called in soc_pcm_trigger() which is atomic. Following issue was found due to execution of clk_get_rate() causes sleep in soc_pcm_trigger(), which shouldn't be blocked. We can reproduce this issue by following > enable CONFIG_DEBUG_ATOMIC_SLEEP=y > compile, and boot > mount -t debugfs none /sys/kernel/debug > while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done & > while true; do aplay xxx; done This patch adds support to .prepare callback, and moves non-atomic clocking operations to it. As .prepare is non-atomic, it is always called before trigger_start/trigger_stop.

When there is no fault bit set in a fault register we skip the fault reporting section for that register. This also skips over saving that registers value. We save the value so we will not double report an error, but if an error clears then returns we will also not report it as we did not save the all cleared register value. Fix this by saving the fault register value in the all clear path. Signed-off-by:
