Support multiple endpoints on SGTL5000 codec port when used in of_graph context. This patch allows to share the codec port between two CPU DAIs. Example: Custom STM32MP157C board uses SGTL5000 audio codec. This codec is connected to two serial audio interfaces, which are configured either as rx or tx. From AsoC point of view the topolgy is the following: // 2 CPU DAIs (SAI2A/B), 1 Codec (SGTL5000) Playback: CPU-A-DAI(slave) -> (master)CODEC-DAI/port0 Record: CPU-B-DAI(slave) <- (master)CODEC-DAI/port0 In the DT two endpoints have to be associated to the codec port: sgtl5000_port: port { sgtl5000_tx_endpoint: endpoint@0 { remote-endpoint = <&sai2a_endpoint>; }; sgtl5000_rx_endpoint: endpoint@1 { remote-endpoint = <&sai2b_endpoint>; }; }; However, when the audio graph card parses the codec nodes, it expects to find DAI interface indexes matching the endpoints indexes. The current patch forces the use of DAI id 0 for both endpoints, which allows to share the codec DAI between the two CPU DAIs for playback and capture streams respectively.

There are two asrc module in imx8qm & imx8qxp, each module has different clock configuration, and the DMA type is EDMA. So in this patch, we define the new clocks, refine the clock map, and include struct fsl_asrc_soc_data for different soc usage. The EDMA channel is fixed with each dma request, one dma request corresponding to one dma channel. So we need to request dma channel with dma request of asrc module.

Add compatible string "fsl,imx8qm-asrc" for imx8qm platform, "fsl,imx8qxp-asrc" for imx8qxp platform. There are two asrc modules in imx8qm & imx8qxp, the clock mapping is different for each other, so add new property "fsl,asrc-clk-map" to distinguish them.

Comparing the voltage of VDDA and VDDIO to determine whether or not to enable VDDC manual override is insufficient. This is a problem in case the VDDA is supplied from different regulator than VDDIO, while both report the same voltage to the regulator framework. In that case where VDDA and VDDIO is supplied by different regulators, the VDDC manual override must not be applied.

For SoundWire support, we added a 'link_mask' to describe the PCB hardware layout. This helped form a signature that can be used as a first-order way of detecting the hardware and selecting the machine driver. The concept of link_mask is however not enough. Some BIOS enable all links, even when there are no devices physically connected. We can also see variations with multiple devices attached on one link, or different types of devices connected on the same link. To accurately represent the hardware, we need to build static tables where each link exposes a list of expected devices represented by the 64-bit _ADR field (which uniquely identifies each device). The new 'links' field is optional when the link_mask is sufficient to represent a platform in a unique way. The existing mechanism to support I2C devices is left as is, it'd be too invasive to change the existing support for _HID and the notion of link is not relevant either.

Any app using ALSA OSS emulation on top of SOF will fail to error from OSS SNDCTL_DSP_SETFMT ioctl. Reported initially as an issue with xournalpp (application using PortAudio with an OSS backend), but applies more generally to other apps using OSS as well. Problem is caused by SOF PCM not supporting repeated calls to hw_params(), without matching calls to pcm_free(). This is however exactly what the ALSA OSS PCM code is doing when it is handling the OSS ioctls. The problem will lead to leaking of DSP resources and eventual failure of DSP PCM_PARAMS IPC.
