* cyclades: add tty refcountingJiri Slaby2009-09-19
| | | | | | | | | | | | | | | | | | | | | While this is not problem for Y card handlers (they are protected by card_lock), Z handlers and other functions may dereference NULL at any point after hangup/close. Even if (tty == NULL) was already performed in the handler. Note that it's not an issue for Y cards just for now. After switching to tty_port_close_* et al. this will be a problem. So add refcounting to them all. Also proc .show doesn't take a tty reference and it should (along with a ldisc one). While at it and changing prototypes (adding tty param), prepend cy_ to functions which don't have it yet.

* tty-ldisc: get rid of tty_ldisc_try_get() helper functionLinus Torvalds2009-09-19
| | | | | | | | | | | | | | | | | | | Now that the /proc/tty/ldiscs handling doesn't play games with 'struct ldisc' any more, the only remaining user of 'tty_ldisc_try_get()' is 'tty_ldisc_get()' (note the lack of 'try'). And we're actually much better off folding the logic directly into that file, since the 'try' part was always about trying to get the ldisc operations, not the ldisc itself: and making that explicit inside of 'tty_ldisc_get()' clarifies the whole semantics.

* tty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscsLinus Torvalds2009-09-19
| | | | | | | | | | | | | | | | | | | | | | The /proc/tty/ldiscs file is totally and utterly un-interested in the "struct tty_ldisc" structures, and only cares about the underlying ldisc operations. So don't make it create a dummy 'struct ldisc' only to get a pointer to the operations, and then destroy it. Instead, we split up the function 'tty_ldisc_try_get()', and create a 'get_ldops()' helper that just looks up the ldisc operations based on the ldisc number. That makes the code simpler to read (smaller and more well-defined helper functions), and allows the /proc functions to avoid creating that useless dummy only to immediately free it again.

| * [WATCHDOG] fix book E watchdog to take WDIOC_SETTIMEOUT arg in secondsChris Friesen2009-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WDIOC_SETTIMEOUT argument is supposed to be a "seconds" value. However, the book E wdt currently treats it as a "period" which is interpreted in a board-specific way. This patch allows the user to pass in a "seconds" value and the driver will set the smallest timeout that is at least as large as specified by the user. It's been tested on e500 hardware and works as expected. The patch only modifies the CONFIG_FSL_BOOKE case, the CONFIG_4xx case is left unmodified as I don't have any hardware to test it on.

Use fixed buffers for bulk and isochronous pipes, also make sure to handle the isochronous-as-bulk case. With fixed buffers there is no need to keep track of used buffers with bi_bufnum. Also, this fixes a potential buffer offset problem where the base offset incorrectly varies with the number of pipes used. The m66592 driver recently got fixed in a similar way.

This adds a new USB gadget driver which bridges the gap and finally wires up the peripheral side as well.
