Commit 7a2da5d7960a ("spi: fsl: Fix driver breakage when SPI_CS_HIGH is not set in spi->mode") broke our MPC8309 board by effectively inverting the boolean value passed to fsl_spi_cs_control. The SPISEL_BOOT signal is used as chipselect, but it's not a gpio, so we cannot rely on gpiolib handling the polarity.
Adapt to the new world order by inverting the logic here. This does assume that the slave sitting at the SPISEL_BOOT is active low, but should that ever turn out not to be the case, one can create a stub gpiochip driver controlling a single gpio (or rather, a single "spo", special-purpose output).

Thanks!

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
