Tegra234 chip scratch register communication between audio and hdmi driver differs slightly in the way it triggers the interrupt compared to legacy chips. Interrupt is triggered by writing non-zero values to verb 0xF80 instead of 31st bit of scratch register. DP MST support changed the NID to be used for scratch register read/write from audio function group NID to Converter widget NID.

The GCAP register on Tegra234 implies no Input Streams(ISS) supported, but the HW output stream descriptor programming should start with offset 0x20*4 from base stream descriptor address. This will be a problem while calculating the offset for output stream descriptor which will be considering input stream also. So here output stream starts with offset 0 which is wrong as HW register for output stream offset starts with 4. So hardcode the input stream numbers to 4 to avoid the issue in offset calculation.

Add hda driver support for the Tegra234 chip. The hdacodec on this chip now supports DP MST feature, HDA block contains azalia controller and one hda-codec instance by supporting 4 independent output streams over DP MST mode.

Implement HDA keep alive (KAE) support for Intel display codecs. When no audio stream is active, the display codec will provide a continuous clock and a valid but silent audio stream to any connected HDMI/DP receiver. Without this, upon starting a new playback stream, initial samples may be lost as many receivers require time to initialize for new clock. This is a new feature in Intel AlderLake-P display codec implementation and replaces the Intel i915 silent-stream extension that has been used on older hardware. Main benefit of the new method is that codec no longer needs to be kept in D0 power state. This patch depends on commit 112a87c4 ("drm/i915/display: program audio CDCLK-TS for keepalives").

The recently introduced coef_mutex for Realtek codec seems causing a deadlock when the relevant code is invoked from the power-off state; then the HD-audio core tries to power-up internally, and this kicks off the codec runtime PM code that tries to take the same coef_mutex. In order to avoid the deadlock, do the temporary power up/down around the coef_mutex acquisition and release. This assures that the power-up sequence runs before the mutex, hence no re-entrance will happen.

The default mixer resume code treats the errors at restoring the modified mixer items as a fatal error, and it returns back to the caller. This ends up in the resume failure, and the device will be come unavailable, although basically those errors are intermittent and can be safely ignored. The problem itself has been present from the beginning, but it didn't hit usually because the code tries to resume only the modified items. But now with the recent commit to forcibly initialize each item at the probe time, the problem surfaced more often, hence it appears as a regression. This patch fixes the regression simply by ignoring the errors at resume.

When parsing the compressed stream the whole buffer descriptor is now read in a single cs_dsp_coeff_read_ctrl; on older firmwares this descriptor is just 4 bytes but on more modern firmwares it is 24 bytes. The current code reads the full 24 bytes regardless, this was working but reading junk for the last 20 bytes. However commit f444da38 ("firmware: cs_dsp: Add offset to cs_dsp read/write") added a size check into cs_dsp_coeff_read_ctrl, causing the older firmwares to now return an error. Update the code to only read the amount of data appropriate for the firmware loaded.

In commit da0363f7 ("ASoC: qcom: Fix for DMA interrupt clear reg overwriting") we changed regmap_write() to regmap_update_bits() so that we can avoid overwriting bits that we didn't intend to modify. Unfortunately this change breaks the case where a register is writable but not readable, which is exactly how the HDMI irq clear register is designed (grep around LPASS_HDMITX_APP_IRQCLEAR_REG to see how it's write only). That's because regmap_update_bits() tries to read the register from the hardware and if it isn't readable it looks in the regmap cache to see what was written there last time to compare against what we want to write there. Eventually, we're unable to modify this register at all because the bits that we're trying to set are already set in the cache. This is doubly bad for the irq clear register because you have to write the bit to clear an interrupt. Given the irq is level triggered, we see an interrupt storm upon plugging in an HDMI cable and starting audio playback. The irq storm is so great that performance degrades significantly, leading to CPU soft lockups. Fix it by using regmap_write_bits() so that we really do write the bits in the clear register that we want to. This brings the number of irqs handled by lpass_dma_interrupt_handler() down from ~150k/sec to ~10/sec.

HD-audio driver handles the multiple instances and keeps the static index that is incremented at each probe. This becomes a problem when user tries to re-bind the device via sysfs multiple times; as the device index isn't cleared unlike rmmod case, it points to the next element at re-binding, and eventually later you can't probe any more when it reaches to SNDRV_CARDS_MAX (usually 32). This patch is an attempt to improve the handling at rebinding. Instead of a static device index, now we keep a bitmap and assigns to the first zero bit position. At the driver remove, in return, the bitmap slot is cleared again, so that it'll be available for the next probe.

The current rt5682_jack_detect_handler() assumes the component and card will always show up and implements an infinite usleep loop waiting for them to show up. This does not hold true if a codec interrupt (or other event) occurs when the card is unbound. The codec driver's remove or shutdown functions cannot cancel the workqueue due to the wait loop. As a result, code can either end up blocking the workqueue, or hit a kernel oops when the card is freed. Fix the issue by rescheduling the jack detect handler in case the card is not ready. In case card never shows up, the shutdown/remove/suspend calls can now cancel the detect task.

This reverts commit 9de2b928 ("ASoC: mediatek: Check for error clk pointer"). With this patch in the tree, Chromebooks running the affected hardware no longer boot. Bisect points to this patch, and reverting it fixes the problem. An analysis of the code with this patch applied shows: ret = init_clks(pdev, clk); if (ret) return ERR_PTR(ret); ... for (j = 0; j < MAX_CLKS && data->clk_id[j]; j++) { struct clk *c = clk[data->clk_id[j]]; if (IS_ERR(c)) { dev_err(&pdev->dev, "%s: clk unavailable\n", data->name); return ERR_CAST(c); } scpd->clk[j] = c; } Not all clocks in the clk_names array have to be present. Only the clocks in the data->clk_id array are actually needed. The code already checks if the required clocks are available and bails out if not. The assumption that all clocks have to be present is wrong, and commit 9de2b928 ("ASoC: mediatek: Check for error clk pointer") needs to be reverted.

Add some coverage of event generation to mixer-test. Rather than doing a separate set of writes designed to trigger events we add a step to the existing write_and_verify() which checks to see if the value we read back from non-volatile controls matches the value before writing and that an event is or isn't generated as appropriate. The "tests" for events then simply check that no spurious or missing events were detected. This avoids needing further logic to generate appropriate values for each control type and maximises coverage. When checking for events we use a timeout of 0. This relies on the kernel generating any event prior to returning to userspace when setting a control. That is currently the case and it is difficult to see it changing, if it does the test will need to be updated. Using a delay of 0 means that we don't slow things down unduly when checking for no event or when events fail to be generated. We don't check behaviour for volatile controls since we can't tell what the behaviour is supposed to be for any given control.

Add support for spi bus in serial-multi-instantiate driver Some peripherals can have either a I2C or a SPI connection to the host (but not both) but use the same HID for both types. So it is not possible to use the HID to determine whether it is I2C or SPI. The driver must check the node to see if it contains I2cSerialBus or SpiSerialBus entries. For backwards-compatibility with the existing nodes I2C is checked first and if such entries are found ONLY I2C devices are created. Since some existing nodes that were already handled by this driver could also contain unrelated SpiSerialBus nodes that were previously ignored, and this preserves that behavior. If there is ever a need to handle a node where both I2C and SPI devices must be instantiated this can be added in future.
