2025-06-23ASoC: codecs: wcd937x: Use simple defines for chipid register valueKrzysztof Kozlowski
The value used to identify chip variant is not an enumeration, but raw value used to compare registers with. The 'enum' is not used in the code at all, so simplify and make it a raw hex value define, so intention will be explicit.

2025-03-19irqdomain: sound: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2025-02-06ASoC: codecs: wcd937x: Add static channel mapping support in wcd937x-sdwMohammad Rafi Shaik
Add static channel mapping between master and slave ports in wcd937x-sdw driver. Currently, the channel mask for each soundwire port is hardcoded in the wcd937x-sdw driver, and the same channel mask value is configured in the soundwire master. The Qualcomm boards like the QCM6490-IDP require different channel mask settings for the soundwire master and slave ports. Implemented logic to read TX/RX channel mappings from device tree properties (qcom,tx-channel-mapping and qcom,rx-channel-mapping). Modified the wcd937x_connect_port to handle master channel masks during port enable/disable operations. Added wcd937x_get_channel_map api to retrieve the current master channel map for TX and RX paths.

2024-10-29ASoC: codecs: wcd937x: relax the AUX PDM watchdogAlexey Klimov
On a system with wcd937x, rxmacro and Qualcomm audio DSP, which is pretty common set of devices on Qualcomm platforms, and due to the order of how DAPM widgets are powered on (they are sorted), there is a small time window when wcd937x chip is online and expects the flow of incoming data but rxmacro is not yet online. When wcd937x is programmed to receive data via AUX port then its AUX PDM watchdog is enabled in wcd937x_codec_enable_aux_pa(). If due to some reasons the rxmacro and soundwire machinery are delayed to start streaming data, then there is a chance for this AUX PDM watchdog to reset the wcd937x codec. Such event is not logged as a message and only wcd937x IRQ counter is increased however there could be a lot of other reasons for that IRQ. There is a similar opportunity for such delay during DAPM widgets power down sequence. If wcd937x codec reset happens on the start of the playback, then there will be no sound and if such reset happens at the end of a playback then it may generate additional clicks and pops noises. On qrb4210 RB2 board without any debugging bits the wcd937x resets are sometimes observed at the end of a playback though not always. With some debugging messages or with some tracing enabled the AUX PDM watchdog resets the wcd937x codec at the start of a playback and there is no sound output at all. In this patch: - TIMEOUT_SEL bit in PDM_WD_CTL2 register is set to increase the watchdog reset delay to 100ms which eliminates the AUX PDM watchdog IRQs on qrb4210 RB2 board completely and decreases the number of unwanted clicks noises; - HOLD_OFF bit postpones triggering such watchdog IRQ till wcd937x codec reset which usually happens at the end of a playback. This allows to actually output some sound in case of debugging.

2024-09-09ASoC: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all drivers below sound/soc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
