* thermal: exynos: Add driver support for exynos5440 TMU sensorAmit Daniel Kachhap2013-08-134-9/+90
| | | | | | | | | | | | | | | This patch modifies TMU controller to add changes needed to work with exynos5440 platform. This sensor registers 3 instance of the tmu controller with the thermal zone and hence reports 3 temperature output. This controller supports upto five trip points. For critical threshold the driver uses the core driver thermal framework for shutdown.

* thermal: exynos: Add TMU features to check instead of using SOC typeAmit Daniel Kachhap2013-08-133-11/+52
| | | | | | | | | | | | | This patch adds several features supported by TMU as bitfields. This features varies across different SOC type and comparing the features present in the TMU is more logical than comparing the soc itself.

* thermal: exynos: Add support to handle many instances of TMUAmit Daniel Kachhap2013-08-135-118/+203
| | | | | | | | | | | | | | | | | This patch adds support to handle multiple instances of the TMU controllers. This is done by removing the static structure to register with the core thermal and creating it dynamically for each instance of the TMU controller. The interrupt is made shared type to handle shared interrupts. Now since the ISR needs the core thermal framework to be registered so request_irq is moved after the core registration is done. Also the identifier of the TMU controller is extracted from device tree alias. This will be used for TMU specific initialisation.

* Thermal: Fix lockup of cpu_down()Steven Rostedt2013-07-221-1/+0
| | | | | | | | | | | | | | | | | | | | | Commit f1a18a105 "Thermal: CPU Package temperature thermal" had code that did a get_online_cpus(), run a loop and then do a put_online_cpus(). The problem is that the loop had an error exit that would skip the put_online_cpus() part. In the error exit part of the function, it also did a get_online_cpus(), run a loop and then put_online_cpus(). The only way to get to the error exit part is with get_online_cpus() already performed. If this error condition is hit, the system will be prevented from taking CPUs offline. The process taking the CPU offline will lock up hard. Removing the get_online_cpus() removes the lockup as the hotplug CPU refcount is back to zero. This was bisected with ktest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's declare platform data a const pointer so that we don't accitentally change it. Also fetch it with dev_get_platdata(). Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In TSG4, register map is 512bytes long and to access all of it, one bit from address byte is used (which bit to use differs for I2C and SPI); Since common code used for TSG3 and TSG4 for I2C, this parameter wrongly used as u8. TSG3 does not access beyond 255 bytes but TSG4 may.
