There are cases where there is no working codec on the soc-audio devices, and snd_soc_suspend() will skip such device when suspending. Yet its counterpart snd_soc_resume() does not check this, causing complaints about spinlock lockup: [ 176.726087] BUG: spinlock lockup on CPU#0, kworker/0:2/1067, d8ab82a8 [ 176.732539] [<80014a14>] (unwind_backtrace+0x0/0xec) from [<805b3fc8>] (dump_stack+0x20/0x24) [ 176.741082] [<805b3fc8>] (dump_stack+0x20/0x24) from [<80322208>] (do_raw_spin_lock+0x118/0x158) [ 176.749882] [<80322208>] (do_raw_spin_lock+0x118/0x158) from [<805b7874>] (_raw_spin_lock_irqsave+0x5c/0x68) [ 176.759723] [<805b7874>] (_raw_spin_lock_irqsave+0x5c/0x68) from [<8002a020>] (__wake_up+0x2c/0x5c) [ 176.768781] [<8002a020>] (__wake_up+0x2c/0x5c) from [<804a6de8>] (soc_resume_deferred+0x3c/0x2b0) [ 176.777666] [<804a6de8>] (soc_resume_deferred+0x3c/0x2b0) from [<8004ee20>] (process_one_work+0x2e8/0x50c) [ 176.787334] [<8004ee20>] (process_one_work+0x2e8/0x50c) from [<8004fd08>] (worker_thread+0x1c8/0x2e0) [ 176.796566] [<8004fd08>] (worker_thread+0x1c8/0x2e0) from [<80053ec8>] (kthread+0xa4/0xb0) [ 176.804843] [<80053ec8>] (kthread+0xa4/0xb0) from [<8000ea70>] (kernel_thread_exit+0x0/0x8) Signed-off-by: Eric Miao <eric.miao@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Ensure we only have one sync during the initial startup of the card by making snd_soc_dapm_sync() a noop on non-instantiated cards. This avoids any bounces due to things like jacks reporting their initial state on partially initialised cards. The callers that don't also get called at runtime should just be removed.

In order to reduce the number of DAPM power checks we run keep a list of widgets which have been changed since the last DAPM run and iterate over that rather than the full widget list. Whenever we change the power state for a widget we add all the source and sink widgets it has to the dirty list, ensuring that all widgets in the path are checked. This covers more widgets than we need to as some of the neighbour widgets won't be connected but it's simpler as a first step. On one system I tried this gave: Power Path Neighbour Before: 207 1939 2461 After: 114 1066 1327 which seems useful. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

For almost all machines the DAI format is a constant, always set to the same thing. This means that not only should we normally set it on init rather than in hw_params() (where it has been for historical reasons) we should also allow users to configure this by setting a variable in the dai_link structure. The combination of these two will make many machine drivers even more data driven. Implement a new dai_fmt field in the dai_link doing just that. Since 0 is a valid value for many format flags and we need to be able to tell if the field is actually set also add one to all the values used to configure formats.

Similarly to PLLs/FLLs some modern CODECs provide selectable system clock sources. When the clock is the clock for a DAI we do not usually need to identify which clock is being configured so can use clk_id for the source clock but with CODEC wide system clocks we will need to specify both the clock being configured and the source. Add a source argument to the CODEC driver set_sysclk() operation to reflect this. As this operation is not as widely used as the DAI set_sysclk() operation the change is not very invasive. We probably ought to go and make the same alternation for DAIs at some point. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

Since quite a few drivers are not managing to flag the cache as needing to be resynced after suspend and it's a reasonable thing to do flag the cache as needing sync automatically when suspending. The expectation is that systems will mainly only keep the CODEC powered when doing audio through the CODEC so we won't actually suspend the device anyway; drivers which want to can override this behaviour when they resume.

The snd_card->driver field contains a driver name string, and in general it shouldn't contain space or special letters. The commit 2b39535b changed the string copy from card->name, but the long name string may contain such letters, thus it may still lead to a segfault. A temporary fix is not to copy the long name string but just keep it empty as the earlier version did.

In preparation for the new ASoC Dynamic PCM support (AKA DSP support). The new ASoC Dynamic PCM core allows DAIs to be dynamically re-routed at runtime between the PCM device end (or Frontend - FE) and the physical DAI (Backend - BE) using regular kcontrols (just like a hardware CODEC routes audio in the analog domain). The Dynamic PCM core therefore must be able to call PCM operations for both the Frontend and Backend(s) DAIs at the same time. Currently we have a global pcm_mutex that is used to serialise the ASoC PCM operations. This patch removes the global mutex and adds a mutex per RTD allowing the PCM operations to be reentrant and allow control of more than one DAI at at time. e.g. a frontend PCM hw_params() could configure multiple backend DAI hw_params() with similar or different hw parameters at the same time.

In preparation for Dynamic PCM support (AKA DSP support). There will be future patches that add support to allow PCMs to be dynamically routed to multiple DAIs at startup and also during stream runtime. This patch moves the ASoC core PCM operaitions into a new file called soc-pcm.c. This will in simplify the ASoC core features into distinct files.

For cards that have two or more DAIs, snd_soc_resume's loop over all DAIs ends up calling schedule_work(deferred_resume_work) once per DAI. Since this is the same work item each time, the 2nd and subsequent calls return 0 (work item already queued), and trigger the dev_err message below stating that a work item may have been lost. Solve this by adjusting the loop to simply calculate whether to run the resume work immediately or defer it, and then call schedule work (or not) one time based on that. Note: This has not been tested in mainline, but only in chromeos-2.6.38; mainline doesn't support suspend/resume on Tegra, nor does the mainline Tegra ASoC driver contain multiple DAIs. It has been compile-checked in mainline. Signed-off-by: Stephen Warren <swarren@nvidia.com> Acked-by: Liam Girdwood <lrg@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
