Merge tag 'tty-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty and serial driver updates from Greg KH: "Here's the large TTY and Serial driver update for 4.7-rc1. A few new serial drivers are added here, and Peter has fixed a bunch of long-standing bugs in the tty layer and serial drivers as normal. Full details in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'tty-4.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (88 commits) MAINTAINERS: 8250: remove website reference serial: core: Fix port mutex assert if lockdep disabled serial: 8250_dw: fix wrong logic in dw8250_check_lcr() tty: vt, finish looping on duplicate tty: vt, return error when con_startup fails QE-UART: add "fsl,t1040-ucc-uart" to of_device_id serial: mctrl_gpio: Drop support for out1-gpios and out2-gpios serial: 8250dw: Add device HID for future AMD UART controller Fix OpenSSH pty regression on close serial: mctrl_gpio: add IRQ locking serial: 8250: Integrate Fintek into 8250_base serial: mps2-uart: add support for early console serial: mps2-uart: add MPS2 UART driver dt-bindings: document the MPS2 UART bindings serial: sirf: Use generic uart-has-rtscts DT property serial: sirf: Introduce helper variable struct device_node *np serial: mxs-auart: Use generic uart-has-rtscts DT property serial: imx: Use generic uart-has-rtscts DT property doc: DT: Add Generic Serial Device Tree Bindings serial: 8250: of: Make tegra_serial_handle_break() static ...
