Merge tag 'tty-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty and serial driver updates from Greg KH: "Here is the big set of tty and serial driver updates for 5.13-rc1. Actually busy this release, with a number of cleanups happening: - much needed core tty cleanups by Jiri Slaby - removal of unused and orphaned old-style serial drivers. If anyone shows up with this hardware, it is trivial to restore these but we really do not think they are in use anymore. - fixes and cleanups from Johan Hovold on a number of termios setting corner cases that loads of drivers got wrong as well as removing unneeded code due to tty core changes from long ago that were never propagated out to the drivers - loads of platform-specific serial port driver updates and fixes - coding style cleanups and other small fixes and updates all over the tty/serial tree. All of these have been in linux-next for a while now with no reported issues" * tag 'tty-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (186 commits) serial: extend compile-test coverage serial: stm32: add FIFO threshold configuration dt-bindings: serial: 8250: update TX FIFO trigger level dt-bindings: serial: stm32: override FIFO threshold properties dt-bindings: serial: add RX and TX FIFO properties serial: xilinx_uartps: drop low-latency workaround serial: vt8500: drop low-latency workaround serial: timbuart: drop low-latency workaround serial: sunsu: drop low-latency workaround serial: sifive: drop low-latency workaround serial: txx9: drop low-latency workaround serial: sa1100: drop low-latency workaround serial: rp2: drop low-latency workaround serial: rda: drop low-latency workaround serial: owl: drop low-latency workaround serial: msm_serial: drop low-latency workaround serial: mpc52xx_uart: drop low-latency workaround serial: meson: drop low-latency workaround serial: mcf: drop low-latency workaround serial: lpc32xx_hs: drop low-latency workaround ...
