2010-08-03panasonic-laptop: fix acpi_pcc_write_sset return valueAxel Lin1-5/+2
In current implementation, acpi_pcc_write_sset return 1 if write is successful, 0 if write is failed. But all the callers consider acpi_pcc_write_sset return 0 if write is successful and return negtive if write is failed.

remove_device() and add_device() are not related to ACPI APIs, it does not make sense to return acpi_status for both functions. Current implementation of add_device() always AE_OK, thus the return value checking for add_device() always return false for ACPI_FAILURE(status).

2010-08-03acerhdf: fix resource reclaim in error pathAxel Lin1-7/+16
Fix resource reclaim in below cases: 1. acerhdf_register_platform() does not properly handle platform_device_alloc() failure and platform_device_add() failure This patch adds error handing for acerhdf_register_platform(). 2. acerhdf_register_platform() return err with acerhdf_dev == NULL. as a result, acerhdf_unregister_platform() does not do resource reclaim in acerhdf_init() error path. This patch adds error handing for acerhdf_register_platform(), thus correct the error handing path in acerhdf_init(). goto out_err instead of err_unreg if acerhdf_register_platform() fail. 3. platform_device_del() should only used in error handling.

2010-08-03compal-laptop: add JHL90, battery & hwmon interfaceRoald Frederickx1-105/+822
The driver now supports the Compal JHL90 (which I use) and it has some added features. The biggest novelties are a battery interface (power_supply) and a temperature and fan control interface (hmwon). It also adds a power-off feature to the backlight subsystem and it exports a few files that can enable/disable wake_on_XXX events. Much of the original code of the old features is still there, but I've changed some names to keep the naming more coherent with the added functionalities. (Sorry for the huge patch) Some technical stuff about the new driver: First of all, I'm not sure if the extra features also work on the other Compal boards. Currently they only get enabled if the DMI data indicates you are on a JHL90 board. Secondly, I've noticed a quirk in my fan controller. I have to re-send the wanted pwm-level to the controller every so often. If I don't do this, the fanspeed will slowly rise until after a couple of minutes it's at full speed. (Note that every normal userland application will probably update the pwm-level every so often anyway, based on temperature readings, so this might not be an issue in practice) If this turns out to be a problem with all the controllers, maybe we should implement a kernel timer and have the driver re-send the pwm level every XX seconds to make this transparent to userspace? (However, I couldn't immediately find a way to do this cleanly.) Additional information can be found in the source comments.

2010-08-03x86 platform driver: intelligent power sharing driverJesse Barnes4-0/+1675
Intel Core i3/5 platforms with integrated graphics support both CPU and GPU turbo mode. CPU turbo mode is opportunistic: the CPU will use any available power to increase core frequencies if thermal headroom is available. The GPU side is more manual however; the graphics driver must monitor GPU power and temperature and coordinate with a core thermal driver to take advantage of available thermal and power headroom in the package. The intelligent power sharing (IPS) driver is intended to coordinate this activity by monitoring MCP (multi-chip package) temperature and power, allowing the CPU and/or GPU to increase their power consumption, and thus performance, when possible. The goal is to maximize performance within a given platform's TDP (thermal design point). Signed-off-by: Jesse Barnes <[email protected]> Signed-off-by: Matthew Garrett <[email protected]>
