This leads to low bus frequency operation problems described in 6fd8b8503a0dc ("spi: spi-imx: Fix out-of-order CS/SCLK operation at low speeds") again. [...]Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next Thanks! [1/1] spi: imx: mx51-ecspi: Reinstate low-speed CONFIGREG delay commit: 135cbd378eab336da15de9c84bbb22bf743b38a5 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.
I messed that one up, here is the incremental fix: https://patchwork.kernel.org/project/spi-devel-general/patch/20210718211143.143557-1-marex@xxxxxxx/
