2006-06-28[PATCH] SPI: infrastructure to initialize spi_device.mode earlyDavid Brownell
This patch adds earlier initialization of spi_device.mode, as needed on boards using nondefault chipselect polarity. An example would be ones using the RS5C348 RTC without an external signal inverter between the RTC chipselect and the SPI controller. Without this mechanism, the first setup() call for that chip would wrongly enable chips, corrupting transfers to/from other chips sharing that SPI bus.

2006-06-28[PATCH] remove active field from tty buffer structurePaul Fulghum
Remove 'active' field from tty buffer structure. This was added in 2.6.16 as part of a patch to make the new tty buffering SMP safe. This field is unnecessary with the more intelligently written flush_to_ldisc that adds receive_room handling. Removing this field reverts to simpler logic where the tail buffer is always the 'active' buffer, which should not be freed by flush_to_ldisc. (active == buffer being filled with new data) The result is simpler, smaller, and faster tty buffer code.

2006-06-28[PATCH] remove TTY_DONT_FLIPPaul Fulghum
Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels to prevent the N_TTY line discipline functions read_chan() and n_tty_receive_buf() from running at the same time. 2.2.15 introduced tty->read_lock to protect access to the N_TTY read buffer, which is the only state requiring protection between these two functions. The current TTY_DONT_FLIP implementation is broken for SMP, and is not universally honored by drivers that send data directly to the line discipline receive_buf function. Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is not universally honored, it is removed.

2006-06-27[PATCH] i2c-i801.c: don't pci_disable_device() after it was just enabledDaniel Ritz
Commit 02dd7ae2892e5ceff111d032769c78d3377df970 ("[PATCH] i2c-i801: Merge setup function") has a missing return 0 in the _probe() function. This means the error path is always executed and pci_disable_device() is called even when the device just got successfully enabled. Having the SMBus device disabled makes some systems (eg. Fujitsu-Siemens Lifebook E8010) hang hard during power-off. Intead of reverting the whole commit this patch fixes it up: - don't ever call pci_disable_device(), also not in the _remove() function to avoid hangs - fix missing pci_release_region() in error path Signed-off-by: Daniel Ritz <daniel.ritz@gmx.ch> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Add the brand new pc8736x_gpio driver. This is mostly based upon scx200_gpio.c, but the platform_dev is treated separately, since its fairly big too. Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-06-27[PATCH] chardev: GPIO for SCx200 & PC-8736x: migrate gpio_dump to common moduleJim Cromie
Since the meaning of config-bits is the same for scx200 and pc8736x _gpios, we can share a function to deliver this to user. Since it is called via the vtable, its also completely replaceable. For now, we keep using printk... Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Now that the read(), write() file-ops are dispatching gpio-ops via the vtable, they are generic, and can be moved 'verbatim' to the nsc_gpio common-support module. After the move, various symbols are renamed to update 'scx200_' to 'nsc_', and headers are adjusted accordingly.
