[1/1] spi: cs42l43: Drop cs35l56 SPI speed down to 11MHz commit: 60980cf5b8c8cc9182e5e9dbb62cbfd345c54074 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

Some internals of the cs35l56 can only support SPI speeds of up to 11MHz. Whilst some use-cases could support higher rates, keep things simple by dropping the SPI speed down to this avoid any potential issues.
