Changes in v9: - Patch 1/2: - modify the comment - change the compatible name to "realtek,rt5575-use-spi" - Patch 2/2: - remove the standalone rt5575_spi_driver module and integrate its functionality into the I2C driver - move the SPI firmware-loading function to rt5575-spi.c - use the match data to distinguish between w/wo flash - minor fixes - Link to v9: https://lore.kernel.org/all/20251211110130.2925541-1-oder_chiou@realtek.com/
Changes in v8: - Patch 1/2: - remove the variable rt5575_spi_ready - use the multiple compatible names to distinguish between w/wo flash - Patch 2/2: - add compatible enum "realtek,rt5575-with-spi" - Link to v8: https://lore.kernel.org/all/20251201105926.1714341-1-oder_chiou@realtek.com/
Changes in v7: - Patch 1/2: - add a caption for the tristates - remove the redundant enum of the SPI command - add the error log in the request firmware failure - change the function name rt5575_spi_fw_loaded to rt5575_fw_load_by_spi - minor fixes - Patch 2/2: - modify commit message - Link to v7: https://lore.kernel.org/all/20251121084112.743518-1-oder_chiou@realtek.com/
Changes in v6: - Patch 1/2: - modify commit message - add select SND_SOC_RT5575 to config SND_SOC_RT5575_SPI in the Kconfig - revise the boiler plate in the head of the file - sort the include files - use a structure to transfer the spi data - use the poll() related function instead the for-loop - revise the UUID to the private ID - minor fixes - Patch 2/2: - modify description - Link to v6: https://lore.kernel.org/all/20251031073245.3629060-1-oder_chiou@realtek.com/
Changes in v2 to v5: - Patch 1/2: - move the firmware to the subdirectory - remove the empty functions - remove the cache_type in the regmap_config - add the error log in the run firmware failure - Patch 2/2: - nothing - Link to v5: https://lore.kernel.org/all/20251015103404.3075684-1-oder_chiou@realtek.com/

The ALC5575 integrates an audio DSP that typically loads its firmware from an external flash via its own SPI host interface. In certain hardware configurations, the firmware can alternatively be loaded through the SPI client interface. The driver provides basic mute and volume control functions. When the SPI client interface is enabled, firmware loading is handled by the SPI driver.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

[4/4] ASoC: rt5575: Add the codec driver for the ALC5575 commit: c7ac7499ac5bb50ab3e00add121822c5c904bc91
Due to Christmas break I wasn't able to continue the review during that time, back at work today :) To be honest, I believe there are still some comments (not related to nitpicks) left uncovered. However, the code in v11 (more like v12) is still a large improvement when compared to v1. For that reason, if it is still feasible you can add my tag:
