Pull tty / serial updates from Greg KH: "Here is the "big" set of tty/serial driver patches for 5.15-rc1 Nothing major in here at all, just some driver updates and more cleanups on old tty apis and code that needed it that includes: - tty.h cleanup of things that didn't belong in it - other tty cleanups by Jiri - driver cleanups - rs485 support added to amba-pl011 driver - dts updates - stm32 serial driver updates - other minor fixes and driver updates All have been in linux-next for a while with no reported problems" * tag 'tty-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (83 commits) tty: serial: uartlite: Use read_poll_timeout for a polling loop tty: serial: uartlite: Use constants in early_uartlite_putc tty: Fix data race between tiocsti() and flush_to_ldisc() serial: vt8500: Use of_device_get_match_data serial: tegra: Use of_device_get_match_data serial: 8250_ingenic: Use of_device_get_match_data tty: serial: linflexuart: Remove redundant check to simplify the code tty: serial: fsl_lpuart: do software reset for imx7ulp and imx8qxp tty: serial: fsl_lpuart: enable two stop bits for lpuart32 tty: serial: fsl_lpuart: fix the wrong mapbase value mxser: use semi-colons instead of commas tty: moxa: use semi-colons instead of commas tty: serial: fsl_lpuart: check dma_tx_in_progress in tx dma callback tty: replace in_irq() with in_hardirq() serial: sh-sci: fix break handling for sysrq serial: stm32: use devm_platform_get_and_ioremap_resource() serial: stm32: use the defined variable to simplify code Revert "arm pl011 serial: support multi-irq request" tty: serial: samsung: Add Exynos850 SoC data tty: serial: samsung: Fix driver data macros style ...
