2007-10-08[POWERPC] spi: mode should be "cpu-qe" instead of "qe"Peter Korsgaard
Mode should be "cpu-qe" for QE in CPU mode. "qe" should be reserved for native QE mode. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
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.

2007-10-04[POWERPC] Document local bus nodes in the device tree, and update cuboot-pq2.Scott Wood
The localbus node is used to describe devices that are connected via a chip select or similar mechanism. The advantages over placing the devices under the root node are that it can be probed without probing other random things under the root, and that the description of which chip select a given device uses can be used to set up mappings if the firmware failed to do so in a useful manner. cuboot-pq2 is updated to match the binding; previously, it called itself chipselect rather than localbus, and used phandle linkage between the actual bus node and the control node (the current agreement is to simply use the fully-qualified address of the control registers, and ignore the overlap with the IMMR node).

2007-10-03[POWERPC] Introduce new CPM device bindings.Scott Wood
This introduces a new device binding for the CPM and other devices on these boards. Some of the changes include: 1. Proper namespace scoping for Freescale compatibles and properties. 2. Use compatible rather than things like device_type and model to determine which particular variant of a device is present. 3. Give the drivers the relevant CPM command word directly, rather than requiring it to have a lookup table based on device-id, SCC v. SMC, and CPM version. 4. Specify the CPCR and the usable DPRAM region in the CPM's reg property. Boards that do not require the legacy bindings should select CONFIG_PPC_CPM_NEW_BINDING to enable the of_platform CPM devices. Once all existing boards are converted and tested, the config option can become default y to prevent new boards from using the old model. Once arch/ppc is gone, the config option can be removed altogether.

Emil Medve points out that this documentation file uses CRLF line endings, which means that if you use [core] autocrlf=input (which makes sense if you ever develop under Windows, for example, or if you use other broken tools) in your git config, git will always complain about the file being dirty.

2007-09-17ACPI: thinkpad-acpi: revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED optionHenrique de Moraes Holschuh
Revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED Kconfig option because it would create a legacy we don't want to support. CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is now moot with the addition of the netlink ACPI event report interface to the ACPI core. Now that ACPI core can send events over netlink, we can use a different strategy to keep backwards compatibility with older userspace, without the need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games. And it arrived before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline kernel, even, which is Good. This patch is in sync with some changes to thinkpad-acpi backports, that will keep things sane for userspace across different combinations of kernel versions, thinkpad-acpi backports (or the lack thereof), and userspace capabilities: Unless a module parameter is used, thinkpad-acpi will now behave in such a way that it will work well (by default) with userspace that still uses only the old ACPI procfs event interface and doesn't care for thinkpad-acpi input devices. It will also always work well with userspace that has been updated to use both the thinkpad-acpi input devices, and ACPI core netlink event interface, regardless of any module parameter. The module parameter was added to allow thinkpad-acpi to work with userspace that has been partially updated to use thinkpad-acpi input devices, but not the new ACPI core netlink event interface. To use this mode of hot key reporting, one has to specify the hotkey_report_mode=2 module parameter. The thinkpad-acpi driver exports the value of hotkey_report_mode through sysfs, as well. thinkpad-acpi backports to older kernels, that do not support the new ACPI core netlink interface, have code to allow userspace to switch hotkey_report_mode at runtime through sysfs. This capability will not be provided in mainline thinkpad-acpi as it is not needed there. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Cc: Michael S.

2007-08-12ACPI: thermal: create "thermal.act=" to disable or override active trip pointLen Brown
thermal.act=-1 disables all active trip points in all ACPI thermal zones. thermal.act=C, where C > 0, overrides all lowest temperature active trip points in all thermal zones to C degrees Celsius. Raising this trip-point may allow you to keep your system silent up to a higher temperature. However, it will not allow you to raise the lowest temperature trip point above the next higher trip point (if there is one). Lowering this trip point may kick in the fan sooner. Note that overriding this trip-point will disable any BIOS attempts to implement hysteresis around the lowest temperature trip point. This may result in the fan starting and stopping frequently if temperature frequently crosses C. WARNING: raising trip points above the manufacturer's defaults may cause the system to run at higher temperature and shorten its life. Signed-off-by: Len Brown <len.brown@intel.com>
2007-08-12ACPI: thermal: create "thermal.nocrt" to disable critical actionsLen Brown
thermal.nocrt=1 disables actions on _CRT and _HOT ACPI thermal zone trip-points. They will be marked as <disabled> in /proc/acpi/thermal_zone/*/trip_points. There are two cases where this option is used: 1. Debugging a hot system crossing valid trip point. If your system fan is spinning at full speed, be sure that the vent is not clogged with dust. Many laptops have very fine thermal fins that are easily blocked. Check that the processor fan-sink is properly seated, has the proper thermal grease, and is really spinning. Check for fan related options in BIOS SETUP. Sometimes there is a performance vs quiet option. Defaults are generally the most conservative. If your fan is not spinning, yet /proc/acpi/fan/ has files in it, please file a Linux/ACPI bug. WARNING: you risk shortening the lifetime of your hardware if you use this parameter on a hot system. Note that this refers to all system components, including the disk drive. 2. Working around a cool system crossing critical trip point due to erroneous temperature reading. Try again with CONFIG_HWMON=n There is known potential for conflict between the the hwmon sub-system and the ACPI BIOS. If this fixes it, notify lm-sensors@lm-sensors.org and linux-acpi@vger.kernel.org Otherwise, file a Linux/ACPI bug, or notify just linux-acpi@vger.kernel.org.
