Merge tag 'tty-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH: "Here is the big TTY / Serial driver merge for 3.11-rc1. It's not all that big, nothing major changed in the tty api, which is a nice change, just a number of serial driver fixes and updates and new drivers, along with some n_tty fixes to help resolve some reported issues. All of these have been in the linux-next releases for a while, with the exception of the last revert patch, which was reported this past weekend by two different people as being needed." * tag 'tty-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (51 commits) Revert "serial: 8250_pci: add support for another kind of NetMos Technology PCI 9835 Multi-I/O Controller" pch_uart: Add uart_clk selection for the MinnowBoard tty: atmel_serial: prepare clk before calling enable tty: Reset itty for other pty n_tty: Buffer work should not reschedule itself n_tty: Fix unsafe update of available buffer space n_tty: Untangle read completion variables n_tty: Encapsulate minimum_to_wake within N_TTY serial: omap: Fix device tree based PM runtime serial: imx: Fix serial clock unbalance serial/mpc52xx_uart: fix kernel panic when system reboot serial: mfd: Add sysrq support serial: imx: enable the clocks for console tty: serial: add Freescale lpuart driver support serial: imx: Improve Kconfig text serial: imx: Allow module build serial: imx: Fix warning when !CONFIG_SERIAL_IMX_CONSOLE tty/serial/sirf: fix error propagation in sirfsoc_uart_probe() serial: omap: fix potential NULL pointer dereference in serial_omap_runtime_suspend() tty: serial: Enable uartlite for ARM zynq ...
