Often part of a more significant series. - Remove abstractions designed to allow a driver to support multiple device types, when they have been around a long time and only the original part showed up. - Initialize spi_device_id arrays using member names following dropping of driver data from drivers that didn't actually use it. - Catch up with i2c_device_id tables added since previous effort to use named initializers for all those. - Use kernel types in a few places instead of standard C ones or bare unsigned.

The main subsystem level change is the work Morimoto-san has been doing to get automatic DAI format selection more widely deployed, and even that is largely changes in the drivers to enable use of the feature rather than framework work. - Conversions of a lot of drivers to use the automatic DAI format selection code from Morimoto-san. - Many fixes and code improvements from bui duc phuc and Morimoto-san. - Fixes for ordering problems in register default tables from Peter Ujfalusi. - Changes to use auto-cleanup for firmware to improve robustness from Takashi Iwai. - Support for firmware on more Awinc devices. - Many changes in the Qualcomm driver stack, mostly around new platform support. - Support for AMD ACP7.B/F, Cirrus Logic CS35L62, Loongson 2K0300, Meson GX formatter and interface, Qualcomm LPI MI2S, SM8475 and WSA855 and Realtek RT1321 VA1/2 and RT766/7. 2026-08-17T07:54:39Z Zeliang Li lizeliang.linux@gmail.com 2026-08-14T19:45:55Z urn:sha1:f6635d64e783ad66d800fefa57f897294004ea65 During runtime resume transitions, loading calibration data blocks to the tas2781 amplifier may intermittently trigger transmission failures or block checksum mismatches (-EAGAIN) due to un-stabilized power rails or I2C bus glitches. The loop in tasdev_load_blk() decrements block->nr_retry and attempts an immediate re-transmission upon receiving -EAGAIN. However, without any inter-retry delay, all available retry slots are exhausted within less than a microsecond—long before the hardware can physically settle. This leads to permanent "ERROR_PRAM_CRCCHK" deadlocks and silent speakers on modern laptops after resuming media. Fix this cleanly by introducing a 2ms usleep_range() delay directly inside the tasdev_load_blk() retry paths prior to each 'continue' statement. This grants the chip sufficient time to stabilize before the next transmission attempt without introducing unnecessary latency on final failures.

That includes the read-only SDCA Controls the driver itself describes: the Latency of every Entity, the Clock Valid of every Clock Source, the actual power state of the Power Domain Entity, the protection status, the algorithm ready flag and the Extension Unit id and version. Most of them are also listed in tas2783_reg_default[] with a placeholder of zero, even though a default for, say, a latency reading is meaningless. Reading such a Control caches its real value, which no longer matches the placeholder, so regcache_sync() then tries to write it back. The peripheral rejects the transaction with -ENODATA and the sync aborts, leaving the rest of the cache unrestored. Add a writeable_reg callback that refuses the read-only Controls and otherwise keeps the previous behaviour. Every selector it lists is the read-only Control of its Entity type in sdca_function.h, and none of the Controls the driver writes is affected: the requested power state, the mutes, the Cluster Index, the protection mode, the algorithm enable and the file download Controls all stay writable. The list is static because the BIOS on the affected machines describes no Smart Amp SDCA function, so the driver runs its fallback tables and sdca_regmap_writeable() is not available to it. It would be good to have the list confirmed against the hardware documentation, and to know whether the read-only Controls belong in tas2783_reg_default[] at all.
