2021-04-08ASoC: codecs: wsa881x: constify static struct snd_soc_dai_opsYe Bin1-1/+1
The snd_soc_dai_ops structures is only stored in the ops field of a snd_soc_dai_driver structure, so make the snd_soc_dai_ops structure const to allow the compiler to put it in read-only memory.

For some reason setting max_register was missed from regmap_config. Without this cat /sys/kernel/debug/regmap/sdw:0:217:2010:0:1/range actually throws below Warning.

Add missing supported rates and formats for the stream, without which attempt to do playback will fail to find any matching rates/format.

2020-09-10ASoC/soundwire: bus: use property to set interrupt masksPierre-Louis Bossart1-0/+1
Add a slave-level property and program the SCP_INT1_MASK as desired by the codec driver. Since there is no DisCo property this has to be an implementation-specific firmware property or hard-coded in the driver. The only functionality change is that implementation-defined interrupts are no longer set for amplifiers - those interrupts are typically for jack detection or acoustic event detection/hotwording.

2020-04-14ASoC: wsa881x: mark read_only_wordlength flagSrinivas Kandagatla1-0/+4
WSA881x works in PDM mode so the wordlength is fixed, which also makes the only field "WordLength" in DPN_BlockCtrl1 register a read-only. Writing to this register will throw up errors with Qualcomm Controller. So use ro_blockctrl1_reg flag to mark this field as read-only so that core will not write to this register.

2020-03-19ASoC: codecs: wsa881x: remove soundwire stream handlingSrinivas Kandagatla1-43/+1
There could be multiple instances of this codec on any platform, so handling stream directly in this codec driver can lead to multiple calls to prepare/enable/disable on the same SoundWire stream. Move this stream handling to machine driver to fix this issue.

2020-01-10ASoC: codecs: add wsa881x amplifier supportSrinivas Kandagatla1-0/+1185
This patch adds support to WSA8810/WSA8815 Class-D Smart Speaker Amplifier. This Amplifier is primarily interfaced with SoundWire. One WSA is used for mono speaker configuration and second one would give stereo setup. This patch is tested on SDM845 based DragonBoard DB845c and Lenovo YOGA C630 Laptop based on SDM850 with WSA8815 speaker amplifiers.
