Thank you! [1/1] arm64: defconfig: Increase the maximum number of 8250/16550 serial ports commit: 8e799ff45baebab781cf392be51a54b1f3fceb23 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant 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. [1] https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux.git -- Vignesh

On some TI SoCs the number of UART instances used can be greater than 4. For example in TI's J721S2 SoC, 11th instance of UART is used as console. So, increase the maximum number of instances to 16.
