2023-04-20spi: cadence-quadspi: use macro DEFINE_SIMPLE_DEV_PM_OPSDhruva Gole
Using this macro makes the code more readable. It also inits the members of dev_pm_ops in the following manner without us explicitly needing to: .suspend = cqspi_suspend, \ .resume = cqspi_resume, \ .freeze = cqspi_suspend, \ .thaw = cqspi_resume, \ .poweroff = cqspi_suspend, \ .restore = cqspi_resume Also get rid of conditional compilation based on CONFIG_PM_SLEEP because it introduces build issues with certain configs when CQSPI_DEV_PM_OPS is just NULL.

2023-04-20ASoC: SOF: Intel: Split the set_power_op for IPC3 and IPC4Ranjani Sridharan
Suspending to S0iX with IPC3 requires the PM_GATE IPC to be sent again to stop the DMA trace. But with IPC4, this is not needed as the trace is stopped with the LARGE_CONFIG_SET IPC. Also, sending the MOD_D0IX IPC to set the D0I3 state again when the DSP is in D0I3 already results in an imbalance in PM runtime states in the firmware. So split the set_power_state ops for IPC3 and IPC4 to avoid sending the MOD_D0IX IPC when the DSP is already in D0I3 with IPC4.

2023-04-20ASoC: SOF: pcm: Add an option to skip platform trigger during stopRanjani Sridharan
In the case of IPC4, a pipeline is only paused during STOP/PAUSE/SUSPEND triggers and the FW keeps the host DMA running when a pipeline is paused. The start/stop tests iterate through STOP/START triggers without involving a hw_free. This means that the pipeline state will only toggle between PAUSED (during the STOP trigger) and RUNNING (during the START trigger). So this test should be treated in the same way as a PAUSE_PUSH/PAUSE_RELEASE test and the DMA should be kept running when toggling the pipeline states between PAUSED and RUNNING. Since there is no way to tell if a STOP trigger will be followed by hw_free or not, this patch proposes to always skip DMA stop during the STOP trigger and handle it later during hw_free. Introduce a new flag in struct sof_ipc_pcm_ops, delayed_platform_trigger, that will be used to ensure that the host DMA will not be stopped during the STOP/PAUSE/RELEASE triggers and set it for IPC4. The platform_trigger call to stop the DMA will be invoked during PCM hw_free instead when the pipeline is reset.

2023-04-20ASoC: Intel: sof_sdw: append codec type to dai link nameBard Liao
The existing sdw_sof machine driver constructs two SoundWire interfaces by direction and sdw link id. It means that we will have exactly the same dai link name if two dai links are on the same sdw link with the same direction. The new Realtek codec has two SoundWire interfaces for jack and DMIC functions and they are treated as different codecs. To create two dai links for jack and DMIC, we need to have different dai link names. This patch suggests to append codec type if there are two or more different types of devices on the same sdw bus.

2023-04-20serial: max310x: fix IO data corruption in batched operationsJan Kundrát
After upgrading from 5.16 to 6.1, our board with a MAX14830 started producing lots of garbage data over UART. Bisection pointed out commit 285e76fc049c as the culprit. That patch tried to replace hand-written code which I added in 2b4bac48c1084 ("serial: max310x: Use batched reads when reasonably safe") with the generic regmap infrastructure for batched operations. Unfortunately, the `regmap_raw_read` and `regmap_raw_write` which were used are actually functions which perform IO over *multiple* registers. That's not what is needed for accessing these Tx/Rx FIFOs; the appropriate functions are the `_noinc_` versions, not the `_raw_` ones. Fix this regression by using `regmap_noinc_read()` and `regmap_noinc_write()` along with the necessary `regmap_config` setup; with this patch in place, our board communicates happily again. Since our board uses SPI for talking to this chip, the I2C part is completely untested.

* use memcpy() instead of the loop (removes c variable) * use remaining parameter directly (removes chunk variable) The code is simpler and easier to follow.

2023-04-20tty: n_gsm: fix redundant assignment of gsm->encodingDaniel Starke
The function gsmld_open() contains a redundant assignment of gsm->encoding. The same value of GSM_ADV_OPT is already assigned to it during the initialization of the struct in gsm_alloc_mux() a few lines earlier. Fix this by removing the redundant second assignment of gsm->encoding in gsmld_open().

2023-04-20i2c: designware: Add doorbell support for MendocinoMario Limonciello
Mendocino and later platform don't use the platform feature mailbox for communication for I2C arbitration, they rely upon ringing a doorbell. Detect the platform by the device ID of the root port and choose the appropriate method.

2023-04-20i2c: designware: Use PCI PSP driver for communicationMario Limonciello
Currently the PSP semaphore communication base address is discovered by using an MSR that is not architecturally guaranteed for future platforms. Also the mailbox that is utilized for communication with the PSP may have other consumers in the kernel, so it's better to make all communication go through a single driver.

Add some test vectors for 128-bit cmac(camellia) as found in draft-kato-ipsec-camellia-cmac96and128-01 section 6.2. The document also shows vectors for camellia-cmac-96, and for VK with a length greater than 16, but I'm not sure how to express those in testmgr. This also leaves cts(cbc(camellia)) untested, but I can't seem to find any tests for that that I could put into testmgr.
