2019-02-02ASoC: dapm: Only power up active channels from a DAICharles Keepax3-8/+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.

2019-02-02ASoC: dapm: fix use-after-free issue with dailink snamePierre-Louis Bossart1-1/+18
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.

2019-02-02ASoC: rsnd: fixup TDM Split mode check for CTUKuninori Morimoto1-13/+12
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 <[email protected]> Signed-off-by: Mark Brown <[email protected]>

2019-01-29ASoC: topology: modify dapm route loading routine and add dapm route unloadingRanjani Sridharan1-16/+86
struct snd_soc_dapm_route has been modified to be a dynamic object so that it can be used to save driver specific data while parsing topology and clean up driver-specific data during driver unloading. 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.

2019-01-28ASoC: add helper to change platform name for all dailinksPierre-Louis Bossart1-0/+31
To reuse the same machine drivers with Atom/SST, Skylake and SOF, we need to change the default platform_name (or platforms->name in the "modern" representation). So far, this override was done with an automatic override, which was broken by a set of changes for DT platforms related to deferred probe handling. This automatic override is actually not really needed, the machine driver can already receive the platform name as a platform_data parameter. This is used e.g. for HDaudio support where we have different PCI aliases used for different platforms. We can reuse the same mechanism and modify the machine drivers to override the dailinks prior to registrating the card. This will require additional work for SOF, but with this helper it'll be just two lines of additional code per machine driver which is reused, not the end of the world. This helper can be simplified when all drivers have transitioned to the "modern" representation of dailinks.

The rationale behind the current calculation is somewhat obscure [1] and can yield slightly wrong dividers in certain cases, which the machine drivers for some boards (like the HiFiBerry DAC+ Pro) seemingly try to circumvent, by updating the rate fraction so as to suit this calculation. The updated calculation should correctly yield the smallest bit clock rate that would fit the frame.

2019-01-28ASoC: pcm512x: Implement the set_bclk_ratio interfaceDimitris Papavasiliou1-4/+24
Some boards, such as the HiFiBerry DAC+ Pro, use a pair of external oscillators, to generate 44.1 or 48kHz multiples and are forced to resort to hacks [1] in order to support 24-bit data without ending up with fractional dividers. This patch allows the machine driver to use 32-bit frames for 24-bit data to avoid such issues. Although the datasheet (p. 15) seems to suggest that only a handful of ratios are supported, it's not very explicit about it, so we allow the full range of values supported by the underlying register in the callback, to avoid needlessly rejecting potentially usable configurations.
