2007-11-14CRISv10 serial driver rewriteJesper Nilsson
New and improved serial driver for CRISv10, take three, with improvements suggested by Jiri Slaby. - Call wait_event_interruptible with a _correct_ and sensible condition. - Removed superfluous test of info->flags & ASYNC_CLOSING, since that is done by wait_event_interruptible. - Moved common code for deregistering DMA and IRQ to deinit_port function. - Use setup_timer when initializing flush_timer. - Convert bit-field for uses_dma_in and uses_dma_out to regular bytes. - Removed CVS tags. - Removed defines and comments for CRIS_BUF_SIZE and TTY_THRESHOLD_THROTTLE (no longer used). - Cleaned up code to pass checkpatch. - Add crisv10.h header file. - Merge of CRISv10 from Axis internal CVS.

2007-11-14serial: only use PNP IRQ if it's validBjorn Helgaas
"Luming Yu" <luming.yu@gmail.com> says: There is a "ttyS1 irq is -1" problem observed on tiger4 which cause the serial port broken. It is because that there is __no__ ACPI IRQ resource assigned for the serial port. So the value of the IRQ for the port is never changed since it got initialized to -1. If PNP supplies a valid IRQ, use it. Otherwise, leave port.irq == 0, which means "no IRQ" to the serial core.

2007-10-18serial: turn serial console suspend a boot rather than compile time optionAndres Salomon
Currently, there's a CONFIG_DISABLE_CONSOLE_SUSPEND that allows one to stop the serial console from being suspended when the rest of the machine goes to sleep. This is incredibly useful for debugging power management-related things; however, having it as a compile-time option has proved to be incredibly inconvenient for us (OLPC). There are plenty of times that we want serial console to not suspend, but for the most part we'd like serial console to be suspended. This drops CONFIG_DISABLE_CONSOLE_SUSPEND, and replaces it with a kernel boot parameter (no_console_suspend). By default, the serial console will be suspended along with the rest of the system; by passing 'no_console_suspend' to the kernel during boot, serial console will remain alive during suspend. For now, this is pretty serial console specific; further fixes could be applied to make this work for things like netconsole. Signed-off-by: Andres Salomon <dilinger@debian.org> Acked-by: "Rafael J.

Enable wakeup from serial ports, make it run-time configurable over sysfs, e.g., echo enabled > /sys/devices/platform/serial8250.0/tty/ttyS0/power/wakeup Requires # CONFIG_SYSFS_DEPRECATED is not set Following suggestions from Alan and Russell moved the may_wake_up checks to serial_core.c. This time actually tested - it does even work. Could someone, please, verify, that put_device after device_find_child is correct? Also would be nice to test with a Natsemi UART, that can wake up the system, if such systems exist. For this you just have to apply the patch below, issue the above "echo" command to one of your Natsemi port, suspend and resume your system, and verify that your Natsemi port still works. If you are actually capable of waking up the system from that port, would be nice to test that as well.

2007-10-04[POWERPC] cpm: Describe multi-user ram in its own device node.Scott Wood
The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.
