2008-07-22istallion: Use helpersAlan Cox
The ldisc needs to be referenced properly when used. The tty layer has a helper for this which should have been used but this driver got missed originally. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-22synclink_gt fix locking in error path of rx enablePaul Fulghum
Fix locking in error path of rx_enable() introduced by synclink_gt-add-rx-dma-buffer-fill-level-control patch. Signed-off-by: Paul Fulghum <paulkf@microgate.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-07-22synclink_gt: add rx DMA buffer fill level controlPaul Fulghum
Add run time control for receive DMA buffer fill level to allow application to control receive latency when using stream oriented serial protocols that pass receive data to application only after a DMA buffer fills. This was previously a compile time option, but run time control is needed when application changes data rate (and latency requirements) or uses different data rates on different ports.

2008-07-22synclink_gt: leave transmitter in reset state after configurationPaul Fulghum
Leave the transmitter in reset state after configuration so that transmit signal is held at mark until transmitter is explicitly enabled by application, otherwise transmitter sends idle pattern.

2008-07-22synclink_gt: improve TIOCOUTQ accuracyPaul Fulghum
Improve the accuracy of TIOCOUTQ value as implemented in chars_in_buffer() method by walking and counting tx DMA buffers, reading controller tx FIFO level and accounting for controller tx shift register. The greatly improves application control of transmit latency at lower data rates.

2008-07-22synclink_gt: improve and simplify write methodPaul Fulghum
Improve write method by allowing multiple HDLC frames to be loaded into tx DMA buffer ring for continuous frame transmission. This simplifies the transmit code by using the common procedures for all serial protocols.

2008-07-22Fix the epca driver to permit epca_setup() to be invoked from the kernel cmdlineDavid Howells
Fix the epca driver to call epca_setup() if digiepca=xxx is included on the command line and the epca driver is built in. epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere along the way that call was removed but not replaced.

2008-07-22Fix the (i)Stallion driver's putchar() and break_ctl() opsDavid Howells
Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's putchar() to return values. Is it actually possible for putchar() or break_ctl() to be called with tty == NULL or can the check be discarded? Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is NULL? Is this even possible? I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks fail.

2008-07-22tty: rework break handlingAlan Cox
Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support.

2008-07-22tty: Mark unconverted drivers as BROKENAlan Cox
