Merge tag 'tty-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty / serial driver updates from Greg KH: "Here is the big set of serial and tty driver updates for 6.3-rc1. Once again, Jiri and Ilpo have done a number of core vt and tty/serial layer cleanups that were much needed and appreciated. Other than that, it's just a bunch of little tty/serial driver updates: - qcom-geni-serial driver updates - liteuart driver updates - hvcs driver cleanups - n_gsm updates and additions for new features - more 8250 device support added - fpga/dfl update and additions - imx serial driver updates - fsl_lpuart updates - other tiny fixes and updates for serial drivers All of these have been in linux-next for a while with no reported problems" * tag 'tty-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (143 commits) tty: n_gsm: add keep alive support serial: imx: remove a redundant check dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties soc: qcom: geni-se: Move qcom-geni-se.h to linux/soc/qcom/geni-se.h tty: n_gsm: add TIOCMIWAIT support tty: n_gsm: add RING/CD control support tty: n_gsm: mark unusable ioctl structure fields accordingly serial: imx: get rid of registers shadowing serial: imx: refine local variables in rxint() serial: imx: stop using USR2 in FIFO reading loop serial: imx: remove redundant USR2 read from FIFO reading loop serial: imx: do not break from FIFO reading loop prematurely serial: imx: do not sysrq broken chars serial: imx: work-around for hardware RX flood serial: imx: factor-out common code to imx_uart_soft_reset() serial: 8250_pci1xxxx: Add power management functions to quad-uart driver serial: 8250_pci1xxxx: Add RS485 support to quad-uart driver serial: 8250_pci1xxxx: Add driver for quad-uart support serial: 8250_pci: Add serial8250_pci_setup_port definition in 8250_pcilib.c tty: pcn_uart: fix memory leak with using debugfs_lookup() ...
