2010-08-03gpio: Add PMIC GPIO block supportAlek Du4-0/+364
Moorestown has PMIC chip which contains GPIO blocks. The PMIC chip is connected to Langwell by SPI interface. So this GPIO driver will be regarded as SPI GPIO expander though the actual GPIO access is through IPC and SRAM. The SPI master contoller will probe this device driver by parsing SPIB table. Cleaned up for new IPC, GPE removed and some printk and other tidying by Alan Cox.

This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys.

2010-08-03toshiba_acpi: make remove_device() and add_device() voidAxel Lin1-11/+3
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). This patch makes add_device() to be void and remove the unnecessary return value checking. remove_proc_entry() won't fail, thus change remove_device() to be void.

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. Current implementation missed a platform_device_put() in acerhdf_exit. This patch fixes it by using platform_device_unregister() instead of platform_device_del() in acerhdf_unregister_platform.

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.
