* ARM: at91: soc: Add init_time callbackMaxime Ripard2014-09-033-0/+7
| | | | | | | | | | | | | | | Introduce an init_time callback to the at91_init_soc structure to be able to tweak the init_time machine callback on a per-soc basis, instead of having to rely on a global one.

* ARM: at91: PIT: (Almost) remove the global variablesMaxime Ripard2014-09-031-71/+108
| | | | | | | | | | | | | | | | | | The timer driver is using some global variables to define some variables it has to use in most of its functions, like the base address. Use some container_of calls to have a single dynamic (and local) variable to hold this content. The only exception is in the !DT case, where the call chain to at91sam926x_ioremap_pit and then at91sam926x_pit_init as init_time makes it hard for the moment to pass the physical address of the timer.

* ARM: at91: PIT: Rework probe functionsMaxime Ripard2014-09-034-64/+51
| | | | | | | | | | | | | | | | | | | | The PIT timer driver until now had a single probe function, disregarding wether it was probed through DT or in the old-style way. This code later on was calling some DT function to retrieve the proper values for its base address, interrupts and clocks. While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE, and the two different probe path were not as clearly separated as they could be. Rework the probe path to take this into account, and switch to CLOCKSOURCE_OF_DECLARE.

* ARM: at91: PIT: Use of_have_populated_dt instead of CONFIG_OFMaxime Ripard2014-09-021-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Until now, the machines, even when CONFIG_OF was enabled, were calling at91sam926x_ioremap_pit to try to map the PIT address using the defined physical address. Obviously, with DT, it's not appropriate anymore, and some code was added to the function to deal with this case. Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled, even though no DT was actually used, which would result in such a case, to this code being executed, without any reason. Moreover, the logic that was here before to bail out of the function just check in the DT to see if the PIT node is there, which is the case in all our DTSI. All this can be made much more straightforward just by using of_have_populated_dt to bail out.

A lot of const cleanups, some reworking and additions to the rfkill quirks in the asus driver, a new driver for generating falling laptop events on Toshibas and some misc fixes. Maybe vendors have stopped inventing things" * 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86: (41 commits) platform/x86: Enable build support for toshiba_haps Documentation: Add file about toshiba_haps module platform/x86: Toshiba HDD Active Protection Sensor asus-nb-wmi: Add wapf4 quirk for the U32U alienware-wmi: make hdmi_mux enabled on case-by-case basis ideapad-laptop: Constify DMI table and other r/o variables asus-nb-wmi.c: Rename x401u quirk to wapf4 compal-laptop: correct invalid hwmon name toshiba_acpi: Add Qosmio X75-A to the alt keymap dmi list toshiba_acpi: Add extra check to backlight code Fix log message about future removal of interface ideapad-laptop: Disable touchpad interface on Yoga models asus-nb-wmi: Add wapf4 quirk for the X550CC intel_ips: Make ips_mcp_limits variables static thinkpad_acpi: Mark volume_alsa_control_{vol,mute} as __initdata fujitsu-laptop: Mark fujitsu_dmi_table[] DMI table as __initconst hp-wmi: Add missing __init annotations to initialization code hp_accel: Constify ACPI and DMI tables fujitsu-tablet: Mark DMI callbacks as __init code dell-laptop: Mark dell_quirks[] DMI table as __initconst ...

| * | platform/x86: Toshiba HDD Active Protection SensorAzael Avalos2014-08-161-0/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver adds support for the built-in accelereometer found on recent Toshiba laptops with HID TOS620A. This driver receives ACPI notify events 0x80 when the sensor detects a sudden move or a harsh vibration, as well as an ACPI notify event 0x81 whenever the movement or vibration has been stabilized. Also provides sysfs entries to get/set the desired protection level and reseting the HDD protection interface.
