2016-10-24ASoC: ak4641: Move register defines to main sourceLars-Peter Clausen
The ak4641 driver only has a few register defines. As they are only used in the one main driver file there is not really a need to keep them in a separate header. Moving them to the main source file allows to remove the now empty header file completely. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-03-04ASoC: hx4700: Register jacks at the card levelLars-Peter Clausen
The jacks are card level elements so use snd_soc_card_jack_new() instead of snd_soc_jack_new() to register them. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-01-09ASoC: hx4700: Automatically disconnect non-connected pinsLars-Peter Clausen
All DAPM input and output pins of the ak4641 are either used in the card's DAPM routing table or are marked as not connected. Set the fully_routed flag of the card instead of manually marking the unused inputs and outputs as not connected. This makes the code a bit shorter and cleaner.

2014-06-03ASoC: Fix wrong argument for card remove callbacksTakashi Iwai
The commit [e1d4d3c8: ASoC: free jack GPIOs before the sound card is freed] introduced snd_soc_card remove callbacks to a few drivers, but they are implemented with a wrong argument type. The callback should receive snd_soc_card pointer instead of snd_soc_pcm_runtime. Fixes: e1d4d3c854f2 ('ASoC: free jack GPIOs before the sound card is freed') Acked-by: Mark Brown <broonie@linaro.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-06-03ASoC: free jack GPIOs before the sound card is freedStephen Warren
This is the same change as commit fb6b8e71448a "ASoC: tegra: free jack GPIOs before the sound card is freed", but applied to all other ASoC machine drivers where code inspection indicates the same problem exists. That commit's description is: ========== snd_soc_jack_add_gpios() schedules a work queue item to poll the GPIO to generate an initial jack status report. If sound card initialization fails, that work item needs to be cancelled, so it doesn't run after the card has been freed. Specifically, freeing the card calls snd_jack_dev_free() which calls snd_jack_dev_disconnect() which sets jack->input_dev = NULL, and input_dev is used by snd_jack_report(), which is called from the work queue item. snd_soc_jack_free_gpios() cancels the work item. The Tegra ASoC machine drivers do call this function in the platform driver remove() callback. However, this happens after the sound card is freed, at least when the card is freed due to errors late during snd_soc_instantiate_card(). This leaves a window where the work item can execute after the card is freed. In next-20140522, sound card initialization does fail for unrelated reasons, and hits the problem described above. To solve this, fix the Tegra ASoC machine drivers to clean up the Jack GPIOs during the snd_soc_card's .remove() callback, which is executed before the overall card object is freed. also, guard the cleanup call based on whether we actually setup up the GPIOs in the first place. Ideally, we'd do the cleanup in a struct snd_soc_dai_link .fini/remove function to match where the GPIOs get set up. However, there is no such callback. ========== Note that I have not even compile-tested this in most cases, since most of the drivers rely on specific mach-* support I don't have enabled, and don't support COMPILE_TEST. Testing by the relevant board maintainers would be useful. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>
