Merge tag 'tty-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
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 ...

-Binding for Cadence UART Controller
-
-Required properties:
-- compatible :
- Use "xlnx,xuartps","cdns,uart-r1p8" for Zynq-7xxx SoC.
- Use "xlnx,zynqmp-uart","cdns,uart-r1p12" for Zynq Ultrascale+ MPSoC.
-- reg: Should contain UART controller registers location and length.
-- interrupts: Should contain UART controller interrupts.
-- clocks: Must contain phandles to the UART clocks
- See ../clocks/clock-bindings.txt for details.
-- clock-names: Tuple to identify input clocks, must contain "uart_clk" and "pclk"
- See ../clocks/clock-bindings.txt for details.
-
-
-Optional properties:
-- cts-override : Override the CTS modem status signal. This signal will
- always be reported as active instead of being obtained from the modem status
- register. Define this if your serial port does not use this pin
-
-Example:
- uart@e0000000 {
- compatible = "cdns,uart-r1p8";
- clocks = <&clkc 23>, <&clkc 40>;
- clock-names = "uart_clk", "pclk";
- reg = <0xE0000000 0x1000>;
- interrupts = <0 27 4>;
- };
