| | | | | | | | | | The button mappings for the Fujitsu Lifebook T901 and T902 are quite different from the generic Lifebook T mappings that are defined. This patch adds mappings that are specific to the hardware on these machines, and allows users to take advantage of features like screen rotation.

* x86, acpi: LLVMLinux: Remove nested functions from Thinkpad ACPIBehan Webster2014-04-061-41/+45
| | | | | | | | | | | | | | | | | | | | | | | The only real change is passing in event_mask to the formerly nested functions. Otherwise it's just moving around function and macro code. This is the only place in the Linux kernel where nested functions are still in use. Nested functions aren't part of the C standards, and complicate the generated code. Although the Linux Kernel has never set out to be entirely C standard compliant, it is increasingly compliant to the standard which is supported by other compilers such as Clang. The LLVMLinux project is working on being able to compile the Linux kernel with Clang. The use of nested functions blocks this effort.

| | | | | | | | | | | | | Recent Toshiba laptops now come equiped with a built in accelerometer (TOS620A) device, but such device does not expose the axes information, however, HCI calls 0x006d and 0x00a6 can be used to query such info.

| | | | | | | | | | | | | | | | Toshiba laptops have two ways of letting userspace know the touchpad has changed state, one with a button on top of the touchpad that simply emmits scancodes whenever enabled/disabled, and another one by pressing Fn-F9 (touchpad toggle) hotkey. This patch adds support to enable/disable the touchpad by exposing the _touchpad_ file in sysfs that simply makes a call to a SCI register, imitating what Toshiba provided software does on Windows.

| | | | | | | | | | | | | | | | | | | | | | Toshiba laptops equiped with an illuminated keyboard can operate in two different modes: Auto and FN-Z. The Auto mode turns on the led on keystrokes and automatically turns it off after some (configurable) time the last key was pressed. The FN-Z mode is used to toggle the keyboard led on/off by userspace. This patch adds support to set the desired KBD mode and timeout via sysfs, creates and registers toshiba::kbd_backlight led device whenever the mode is set to FN-Z. The acceptable values for mode are: 1 (Auto) and 2 (Fn-Z) The time values range are: 1-60 seconds Signed-off-by: Azael Avalos <coproscefalo@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>

The behaviour of the driver changes whereby previously when passed 1 it tried to turn on backlight immediately now it does nothing.

* Fix sleep / suspend keys for Toughbook CF-51Stefan Seyfried2014-04-061-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi all, my panasonic cf-51 does no longer react to the suspend and hibernate keys. I cannot tell when this started since I no longer use the machine on a daily basis, but I suspect it started when userspace switched from using /proc/acpi/event to the input layer, wich was quite some time ago ;-) Today I investigated the issue and found that the firmware simply does not generate any event on "key down" for those keys, but only on "key up". The attached patch works around the problem.

Because of this, the input layer does ignore both keys. The work around is to generate a key down event before the key up. To avoid double events on non-broken firmware, this is only done if no key down is ever seen for those keys.

All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.

| * | fujitsu-laptop: fix error return codeJulia Lawall2014-01-211-8/+7Star

In acpi_fujitsu_add, result does not seem useful; it would seem reasonable to propagate the return value of acpi_bus_update_power in an error case. On the other hand, in the case of acpi_fujitsu_hotkey_add, there is an initialization of result that can lead to what looks like a failure case, but that does not abort the function. The variable result is kept for this case. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
| * | dell-laptop: Only install the i8042 filter when rfkill is activeHans de Goede2014-01-211-31/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Installing the i8042 filter is not useful on machines where rfkill is not whitelisted, so move the filter installation into dell_setup_rfkill, after the whitelist check. This avoids doing a needless and potentially troublesome rfkill query (dell_send_request(buf, 17, 11)) when the wireless Fn key gets pressed on non whitelisted laptops. This patch was written as a result of: https://bugzilla.redhat.com/show_bug.cgi?id=1045807 It is not yet clear if this is related, but it is a good idea to not register the i8042 filter in general.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <david.e.box@linux.intel.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
| * | drivers: platform: Include appropriate header file in mxm-wmi.cRashika Kheria2014-01-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes appropriate header file linux/mxm-wmi.h in x86/mxm-wmi.c because functions mxm_wmi_call_mxds(), mxm_wmi_call_mxmx() and mxm_wmi_supported() have their prototype declaration in linux/mxm-wmi.h. Thus, it also eliminates the following warnings in x86/mxm-wmi.c: drivers/platform/x86/mxm-wmi.c:43:5: warning: no previous prototype for ‘mxm_wmi_call_mxds’ [-Wmissing-prototypes] drivers/platform/x86/mxm-wmi.c:68:5: warning: no previous prototype for ‘mxm_wmi_call_mxmx’ [-Wmissing-prototypes] drivers/platform/x86/mxm-wmi.c:93:6: warning: no previous prototype for ‘mxm_wmi_supported’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Signed-off-by: Matthew Garrett <matthew.garrett@nebula.com>
