|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.1 Lots and lots of new drivers so far, a highlight being the MediaTek BTCVSD which is a driver for a Bluetooth radio chip - the first such driver we've had upstream. Hopefully we will soon also see a baseband with an upstream driver! - Support for only powering up channels that are actively being used. - Quite a few improvements to simplify the generic card drivers, especially the merge of the SCU cards into the main generic drivers. - Lots of fixes for probing on Intel systems, trying to rationalize things to look more standard from a framework point of view. - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341, Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

This comes from the topology design which operates in multiple passes.

If platform/board uses MIXer, situation will be more complex. To avoid duplicate DVC kctrl registration when MIXer was used, it had original flags. But it was issue when sound card was re-binded, because no one can't cleanup this flags then. To solve this issue, commit 9c698e8481a15237a ("ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()") checks registered card->controls, because if card was re-binded, these were cleanuped automatically. This patch could solve re-binding issue. But, it start to avoid MIX kctrl. To solve these issues, we need below. To avoid card re-binding issue: check registered card->controls To avoid duplicate DVC registration: check registered rsnd_kctrl_cfg To allow multiple MIX registration: check registered rsnd_kctrl_cfg This patch do it.

| | * ASoC: core: Allow soc_find_component lookups to match parent of_nodeCharles Keepax2019-01-251-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device. As such when looking up components in soc_find_components we should match against both the devices of_node and the devices parent's of_node, as is already done in the rest of the ASoC core. This causes regressions for some DAI links at the moment as soc_find_component was recently added as a check in soc_init_dai_link.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For callbacks configuring the state of the components (trigger, set_params, ack and set_metadata) simplify the code a little and make intention clearer by aborting as soon as an error is encountered. The operation has already failed and there is nothing to be gained from processing the callbacks on additional components. The operations currently abort after the callbacks, so this simply shortens the error path. For callbacks returning information from the driver (copy, get_metadata, pointer, get_codec_caps, get_caps and get_params) only look for the first callback provided, currently the code will call every callback only returning the information provided by the last. Since we can only return one set of data, it makes no sense to request the data from every component. Again this just makes the currently supported feature set a little more clear.

If the digital core is activated too early, or even before the ADC is powered up, audible artifacts appear at the beginning of the recorded signal. The digital core is also needed for playback, so when recording starts it may already be enabled. This means we cannot get the power sequence correct when we want to be able to start recording after playback. As a workaround put the MIC mute switch into the DAPM routes. This way we can keep the recording disabled until the MIC Bias has settled and thus get rid of audible artifacts.

Currently remove_link() is only used to remove the FE dai link which is created by the topology. The BE dai link cannot however be unloaded in snd_soc_tplg_component _remove(), which is problematic if anything needs to be released or reinitialized. This patch aligns the definitions of dynamic types with the existing UAPI and adds a new remove_backend_link() routine to unload the the BE dai link when snd_soc_tplg_component_remove() is invoked.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally snd_soc_init_platform was not cleaning up its pointers, this was fixed to always reallocate dynamic memory but created a memory leak when snd_soc_init_platform was called multiple times during the same probe attempt and also threw away any changes made to the struct between calls. In order to avoid reallocating memory that is still valid, the behaviour will be changed to clear the dynamically set pointers on a probe error and a unregister event and snd_soc_init_platform will go back to its original behaviour of only allocating null pointers so it will stop throwing away valid changes.

| * | ASoC: dapm: Add warnings for widget overwrite when adding routeZhiwei Jiang2019-02-021-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, in some complex cases, more than one widgets have same name and registed from differnt dapm context, and route add from another context too. When snd_soc_dapm_add_route, the previous registered widget will overwritten by the latest same name widget, will cause unexpect error. For Asoc framework we cant avoid this situation and we cant decide which widget that wanted with route. At least we can give users a notice.

| * | ASoC: dapm: Only power up active channels from a DAICharles Keepax2019-02-023-8/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all widgets attached to a DAI link will be powered up when the DAI is active, however this may include routes that are not actually in use if there are unused channels available on the DAI. The macros for creating AIF widgets already include an entry for slot, it is proposed to change that to channel. The effective difference here being respresenting the logical channel index rather than the physical slot index. The CODECs currently using the slot entry on the DAPM_AIF macros are using it in a manner consistent with this, the CODECs not using it just have the field set to zero. A variable is added to snd_soc_dapm_widget to represent this channel index and then for each AIF widget attached to a DAI this is compared against the number of channels on the stream. Enabling the links for those which will be in use. This has the nice property that the CODECs which haven't used the slot/channel entry in the macro will function exactly as before due to all the AIF widgets having a channel of zero and a stream by definition having at least one channel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7620fe9161ce ("ASoC: topology: fix memory leak in soc_tplg_dapm_widget_create") fixed a memory leak issue, but additional tests and KASAN reports show a use-after-free in soc-dapm. The widgets are created with a kmemdup operating on a template. The "name" string is also duplicated, but the "sname" string is not. As a result, when the template is freed after widget creation, its sname string is still used. Fix by explicitly duplicating the "sname" string, and freeing it when required.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renesas sound card need to judge that whether it is using "TDM Split mode". To judge it and for other purpose, it has rsnd_parse_connect_simple() and rsnd_parse_connect_graph(), but these are using different judgement policy for TDM Split mode. It is pointless and confusable. This patch add new rsnd_parse_tdm_split_mode() and use common judgement policy for simple-card/audio-graph. Without this patch, CTU will be judged as TDM Split mode on audio-graph card. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

This patch makes the following changes to accomplish the above: 1. Set the dobj member of snd_soc_dapm_route during the SOC_TPLG_PASS_GRAPH pass of topology parsing. 2. Add the remove_route() routine that will be called while removing all dynamic objects from the component driver.
