Merge branch 'depends/tty' into next/headers

Merging in Greg's tty tree including a cleanup patch needed by the OMAP serial
header cleanups.

* depends/tty: (305 commits)
  tty/serial/8250: Make omap hardware workarounds local to 8250.h
  serial/8250/8250_early: Prevent rounding error in uartclk
  serial: samsung: use clk_prepare_enable and clk_disable_unprepare
  TTY: Report warning when low_latency flag is wrongly used
  console: use might_sleep in console_lock
  TTY: move tty buffers to tty_port
  TTY: add port -> tty link
  TTY: tty_buffer, cache pointer to tty->buf
  TTY: move TTY_FLUSH* flags to tty_port
  TTY: n_tty, propagate n_tty_data
  TTY: move ldisc data from tty_struct: locks
  TTY: move ldisc data from tty_struct: read_* and echo_* and canon_* stuff
  TTY: move ldisc data from tty_struct: bitmaps
  TTY: move ldisc data from tty_struct: simple members
  TTY: n_tty, add ldisc data to n_tty
  TTY: audit, stop accessing tty->icount
  TTY: n_tty, remove bogus checks
  TTY: n_tty, simplify read_buf+echo_buf allocation
  TTY: hci_ldisc, remove invalid check in open
  TTY: ldisc, wait for idle ldisc in release
