Merge tag 'tty-5.14-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 and serial driver patches for 5.14-rc1. A bit more than normal, but nothing major, lots of cleanups. Highlights are: - lots of tty api cleanups and mxser driver cleanups from Jiri - build warning fixes - various serial driver updates - coding style cleanups - various tty driver minor fixes and updates - removal of broken and disable r3964 line discipline (finally!) All of these have been in linux-next for a while with no reported issues" * tag 'tty-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (227 commits) serial: mvebu-uart: remove unused member nb from struct mvebu_uart arm64: dts: marvell: armada-37xx: Fix reg for standard variant of UART dt-bindings: mvebu-uart: fix documentation serial: mvebu-uart: correctly calculate minimal possible baudrate serial: mvebu-uart: do not allow changing baudrate when uartclk is not available serial: mvebu-uart: fix calculation of clock divisor tty: make linux/tty_flip.h self-contained serial: Prefer unsigned int to bare use of unsigned serial: 8250: 8250_omap: Fix possible interrupt storm on K3 SoCs serial: qcom_geni_serial: use DT aliases according to DT bindings Revert "tty: serial: Add UART driver for Cortina-Access platform" tty: serial: Add UART driver for Cortina-Access platform MAINTAINERS: add me back as mxser maintainer mxser: Documentation, fix typos mxser: Documentation, make the docs up-to-date mxser: Documentation, remove traces of callout device mxser: introduce mxser_16550A_or_MUST helper mxser: rename flags to old_speed in mxser_set_serial_info mxser: use port variable in mxser_set_serial_info mxser: access info->MCR under info->slock ...
