Merge tag 'tty-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH: "Here is the large tty/serial patchset for 4.13-rc1. A lot of tty and serial driver updates are in here, along with some fixups for some __get/put_user usages that were reported. Nothing huge, just lots of development by a number of different developers, full details in the shortlog. All of these have been in linux-next for a while" * tag 'tty-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (71 commits) tty: serial: lpuart: add a more accurate baud rate calculation method tty: serial: lpuart: add earlycon support for imx7ulp tty: serial: lpuart: add imx7ulp support dt-bindings: serial: fsl-lpuart: add i.MX7ULP support tty: serial: lpuart: add little endian 32 bit register support tty: serial: lpuart: refactor lpuart32_{read|write} prototype tty: serial: lpuart: introduce lpuart_soc_data to represent SoC property serial: imx-serial - move DMA buffer configuration to DT serial: imx: Enable RTSD only when needed serial: imx: Remove unused members from imx_port struct serial: 8250: 8250_omap: Fix race b/w dma completion and RX timeout serial: 8250: Fix THRE flag usage for CAP_MINI tty/serial: meson_uart: update to stable bindings dt-bindings: serial: Add bindings for the Amlogic Meson UARTs serial: Delete dead code for CIR serial ports serial: sirf: make of_device_ids const serial/mpsc: switch to dma_alloc_attrs tty: serial: Add Actions Semi Owl UART earlycon dt-bindings: serial: Document Actions Semi Owl UARTs tty/serial: atmel: make the driver DT only ...
