* ALSA: hda/tegra - Improve error reportingThierry Reding2015-05-181-6/+19

* ALSA: hda/hdmi - Implement Tegra-specific patchThierry Reding2015-05-181-1/+166
| | | | | | | | | | | | | | | The HDMI codec on NVIDIA Tegra SoCs has a feature that doesn't exist on the MCP or GPU variants. The highest bit in the vendor-defined scratch registers can be used to trigger an interrupt in the HDMI codec, which is signalled to the HDMI driver. This can be used to pass information, such as the HDA format, to the HDMI driver so that it can reconfigure itself accordingly. While at it, change the name of the codec to Tegra124 since there are no other SoCs in the Tegra12x family. There isn't really a Tegra12x family.

* ALSA: info: Register proc entries recursively, tooTakashi Iwai2015-05-182-15/+40
| | | | | | | | | | | | | | | | | | | | | | The commit [c560a6797e3b: ALSA: core: Remove child proc file elements recursively] converted snd_card_proc_new() with the normal snd_info_*() call and removed snd_device chain for such info entries. However, it misses one point: the creation of the proc entry was managed by snd_device chain in the former code, and now it's also gone, which results in no proc files creation at all. Mea culpa. This patch makes snd_info_card_register() creating the all pending child proc entries in a shot. Also, since snd_card_register() might be called multiple times, this function is also changed to be callable multiple times. Along with the changes above, now the linked list of snd_info_entry is added at creation time instead of snd_info_register() for keeping eyes of pending info entries.

* ALSA: info: Fix leaks of child entries at snd_info_free_entry()Takashi Iwai2015-05-181-3/+3
| | | | | | | | | | | | snd_info_free_entry() releases the all children nodes as well, but due to the wrong timing of releasing the link, the children nodes may be disconnected but left unreleased. This patch fixes it by moving the link free at the right position. Also it eases list_for_each_entry() without _safe option in snd_info_disconnect() because it no longer frees the children nodes there.

| | | | | | | | | | | | | In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power wells, so it's necessary to reset display audio codecs when power well on, otherwise display audio codecs will disappear when resume from low power state.

If the controller doesn't need the power, the power will be released the after probe, and a codec that needs the power can request/release the power via bus link_power ops. Background: - For Haswell/Broadwell, which has a separate HD-A controller for display audio, both the controller and the display codec are in the i915 power well. - For Baytrail/Braswell, the display and analog audio share the same HDA controller and link, and only the display codec is in the i915 power well. - For Skylake, the display and analog audio share the same HDA controller but use separate links. Only the display codec is in the i915 power well. And in legacy mode we take the two links as one. So it can follow Baytrail/Braswell.

| * | | ALSA: jack: implement kctl creating for jack devicesJie Yang2015-04-274-6/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the ALSA jack core registers only input devices for each jack registered. These jack input devices are not readable by userspace devices that run as non root. This patch series will implement kctls inside the core jack part, including kctls creating, status changing report, for both HD-Audio and ASoC jack. This allows non root userspace to read jack status and act on it. This patch adds a new API called snd_jack_add_new_kctl(), which will create a kcontrol, add it to the card, and also attach it to the jack kctl list. This patch also initialises the jack kctl list after jack is newed, and reports kctl status when jack insertion/removal events occur. snd_jack_new() is updated in the following patches to also support creating phantom jacks and jack kcontrols. We then remove these duplicated features from HDA jack and have jack kctls handled by core throughout HDA and ASoC.

| | * | ALSA: hda - Replace hda_bus_ops with static bindingTakashi Iwai2015-04-163-72/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally hda_bus takes its own ops (hda_bus_ops) to allow different controller drivers giving individual implementations of PCM attachment, etc. But this never happened and we finally merged both codec and controller helper codes. Thus there is no merit to keep the indirect accesses to functions via hda_bus_ops. This patch replaces these calls with the direct local function calls for simplification.

This reduces lots of lines, finally. Since struct hda_bus is now embedded into struct azx, snd_hda_bus_new() is moved and expanded from hda_codec.c to hda_controller.c, accordingly. Also private_free bus ops and private_data field are removed because we no longer need to point azx object from bus (we can use container_of()) The spin locks are consolidated into the single one, bus->reg_lock.
