platform: x86: dell-smo8800: Dell Latitude freefall driver (ACPI SMO8800/SMO8810)

2014-06-10T23:11:10Z

This acpi driver provide supports for freefall sensors SMO8800/SMO8810 which can be found on Dell Latitude laptops. Driver register /dev/freefall misc device which has same interface as driver hp_accel freefall driver. So any existing applications for HP freefall sensor /dev/freefall will work for with this new driver for Dell Latitude laptops too.

X86 platform: New BayTrail IOSF-SB MBI driver

2014-01-21T13:44:17Z

Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit devices connected to the system fabric. This driver implements access to this interface on BayTrail platforms. This is a requirement for drivers that need access to unit registers on the platform (e.g. accessing the PUNIT for power management features such as RAPL). Serialized access is handled by all exported routines with spinlocks. The API includes 3 functions for access to unit registers: int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr) int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr) int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask) port: indicating the unit being accessed opcode: the read or write port specific opcode offset: the register offset within the port mdr: the register data to be read, written, or modified mask: bit locations in mdr to change Returns nonzero on error Note: GPU code handles access to the GFX unit. Therefore access to that unit with this driver is disallowed to avoid conflicts. Signed-off-by: David E. Box Signed-off-by: Matthew Garrett

platform: add chrome platform directory

2013-11-20T23:51:03Z

It makes sense to split out the Chromebook/Chromebox hardware platform drivers to a separate subdirectory, since some of it will be shared between ARM and x86. This moves over the existing chromeos_laptop driver without making any other changes, and adds appropriate Kconfig entries for the new directory. It also adds a MAINTAINERS entry for the new subdir.

Add trivial driver to disable Intel Smart Connect

2013-07-10T19:42:49Z

Intel Smart Connect is an Intel-specific ACPI interface for configuring devices to wake up at regular intervals so they can pull down mail or other internet updates, and then go to sleep again. If a user enables this in Windows and then reboots into Linux, the device may wake up if it's put to sleep. Since there's no Linux userland support for any of this, the machine will then remain awake until something else puts it back to sleep. I haven't figured out all that much about how this works (there's a bunch of different ACPI calls available on the device), but this seems to be enough to turn it off. We can add more features to this driver if anyone ever cares about figuring out what the rest of the calls do or writing some Linux userspace to implement the rest of it.

Add support driver for Intel Rapid Start Technology

2013-07-10T19:42:48Z

Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.
