Merge branch 'omap-serial' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM OMAP serial updates from Russell King: "This series is a major reworking of the OMAP serial driver code fixing various bugs in the hardware-assisted flow control, extending up into serial_core for a couple of issues. These fixes have been done as a set of progressive changes and transformations in the hope that no new bugs will be introduced by this series. The problems are many-fold, from the driver not being informed about updated settings, to the driver not knowing what the intentions of the upper layers are. The first four patches tackle the serial_core layer, allowing it to provide the necessary information to drivers, and the remaining patches allow the OMAP serial driver to take advantage of this. This brings hardware assisted RTS/CTS and XON/OFF flow control into a useful state. These patches have been in linux-next for most of the last cycle; indeed they predate the previous merge window. They've also been posted to the OMAP people." * 'omap-serial' of git://git.linaro.org/people/rmk/linux-arm: (21 commits) SERIAL: omap: fix hardware assisted flow control SERIAL: omap: simplify (2) SERIAL: omap: move xon/xoff setting earlier SERIAL: omap: always set TCR SERIAL: omap: simplify SERIAL: omap: don't read back LCR/MCR/EFR SERIAL: omap: serial_omap_configure_xonxoff() contents into set_termios SERIAL: omap: configure xon/xoff before setting modem control lines SERIAL: omap: remove OMAP_UART_SYSC_RESET and OMAP_UART_FIFO_CLR SERIAL: omap: move driver private definitions and structures to driver SERIAL: omap: remove 'irq_pending' bitfield SERIAL: omap: fix MCR TCRTLR bit handling SERIAL: omap: fix set_mctrl() breakage SERIAL: omap: no need to re-read EFR SERIAL: omap: remove setting of EFR SCD bit SERIAL: omap: allow hardware assisted IXANY mode to be disabled SERIAL: omap: allow hardware assisted rts/cts modes to be disabled SERIAL: core: add throttle/unthrottle callbacks for hardware assisted flow control SERIAL: core: add hardware assisted h/w flow control support SERIAL: core: add hardware assisted s/w flow control support ...
