2018-05-01Input: atmel_mxt_ts - add missing compatible strings to OF device tableJavier Martinez Canillas1-0/+5
Commit af503716ac14 ("i2c: core: report OF style module alias for devices registered via OF") fixed how the I2C core reports the module alias when devices are registered via OF. But the atmel_mxt_ts driver only has an "atmel,maxtouch" compatible in its OF device ID table, so if a Device Tree is using a different one, autoload won't be working for the module (the matching works because the I2C device ID table is used as a fallback). So add compatible strings for each of the entries in the I2C device table.

2018-05-01Input: atmel_mxt_ts - fix the firmware updateNick Dyer1-76/+110
The automatic update mechanism will trigger an update if the info block CRCs are different between maxtouch configuration file (maxtouch.cfg) and chip. The driver compared the CRCs without retrieving the chip CRC, resulting always in a failure and firmware flashing action triggered. Fix this issue by retrieving the chip info block CRC before the check. Note that this solution has the benefit that by reading the information block and the object table into a contiguous region of memory, we can verify the checksum at probe time. This means we make sure that we are indeed talking to a chip that supports object protocol correctly. Using this patch on a kevin chromebook, the touchscreen and touchpad drivers are able to match the CRC: atmel_mxt_ts 3-004b: Family: 164 Variant: 14 Firmware V2.3.AA Objects: 40 atmel_mxt_ts 5-004a: Family: 164 Variant: 17 Firmware V2.0.AA Objects: 31 atmel_mxt_ts 3-004b: Resetting device atmel_mxt_ts 5-004a: Resetting device atmel_mxt_ts 3-004b: Config CRC 0x573E89: OK atmel_mxt_ts 3-004b: Touchscreen size X4095Y2729 input: Atmel maXTouch Touchscreen as /devices/platform/ff130000.i2c/i2c-3/3-004b/input/input5 atmel_mxt_ts 5-004a: Config CRC 0x0AF6BA: OK atmel_mxt_ts 5-004a: Touchscreen size X1920Y1080 input: Atmel maXTouch Touchpad as /devices/platform/ff140000.i2c/i2c-5/5-004a/input/input6 Signed-off-by: Nick Dyer <nick.dyer@shmanahar.org> Acked-by: Benson Leung <bleung@chromium.org> [Ezequiel: minor patch massage] Signed-off-by: Ezequiel Garcia <ezequiel@collabora.com> Tested-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

As reported by several folks systemd and other applications rely on the documented behaviour of CLOCK_MONOTONIC on Linux and break with the above changes. After resume daemons time out and other timeout related issues are observed. Rafael compiled this list: * systemd kills daemons on resume, after >WatchdogSec seconds of suspending (Genki Sky). [Verified that that's because systemd uses CLOCK_MONOTONIC and expects it to not include the suspend time.] * systemd-journald misbehaves after resume: systemd-journald[7266]: File /var/log/journal/016627c3c4784cd4812d4b7e96a34226/system.journal corrupted or uncleanly shut down, renaming and replacing. (Mike Galbraith). * NetworkManager reports "networking disabled" and networking is broken after resume 50% of the time (Pavel). [May be because of systemd.] * MATE desktop dims the display and starts the screensaver right after system resume (Pavel). * Full system hang during resume (me). [May be due to systemd or NM or both.] That happens on debian and open suse systems. It's sad, that these problems were neither catched in -next nor by those folks who expressed interest in this change. Reported-by: Rafael J.

The way we are supposed to put controller to sleep and wake it up does not depend on the platform, but rather on controller itself, so we want to get rid of suspend mode in platform data (and eventually get rid of platform data completely). Unfortunately some early chromebooks (the original Pixel, Acer C720) were shipped with config that requires manually re-enabling touch reporting in T9. We will sort it out, but in the meantime let's switch to a simple DMI quirk. We'll keep pdata->suspend_mode for now and remove it when we rework chromeos-laptop driver.

2018-04-04Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpadOndrej Zary1-0/+17
The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. [ See the new nds32 port merged in the previous commit for the next generation of "one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem" - Linus ] The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar [ Palmer Dabbelt points out that RISC-V support is in mainline gcc since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]" This really says it all: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ...

The primary interface for the touchpad device in Thinkpad L570 is SMBus, so ALPS overlooked PS2 interface Firmware setting of TrackStick, and shipped with TrackStick otp bit is disabled. The address 0xD7 contains device number information, so we can identify the device by checking this value, but to access it we need to enable Command mode, and then re-enable the device. Devices shipped in Thinkpad L570 report either 0x0C or 0x1D as device numbers, if we see them we assume that the devices are DualPoints. The same issue exists on Dell Latitude 7370.

2018-03-07Revert "Input: synaptics - Lenovo Thinkpad T460p devices should use RMI"Arkadiusz Hiler1-1/+0
This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which caused the following issues: 1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working after suspend-resume cycle. Due to strange state of the device another suspend is impossible. The following dmesg errors can be observed: thinkpad_acpi: EC reports that Thermal Table has changed rmi4_smbus 7-002c: failed to get SMBus version number! rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask. rmi4_f01 rmi4-00.fn01: Failed to restore normal operation: -16. rmi4_f01 rmi4-00.fn01: Resume failed with code -16. rmi4_physical rmi4-00: Failed to suspend functions: -16 rmi4_smbus 7-002c: Failed to resume device: -16 PM: resume devices took 0.640 seconds rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-16). rmi4_physical rmi4-00: rmi_driver_clear_irq_bits: Failed to change enabled interrupts! rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts! psmouse: probe of serio3 failed with error -1 2. On another T460p with BIOS version 2.15 two finger scrolling gesture on the touchpad stops working after suspend-resume cycle (about 75% reproducibility, when it still works, the scrolling gesture becomes laggy). Nothing suspicious appears in the dmesg. Analysis form Richard Schütz: "RMI is unreliable on the ThinkPad T460p because the device is affected by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow ACPI SystemIO OpRegion to conflict with PCI BAR")." The affected devices often show: i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited Reported-by: Richard Schütz <rschuetz@uni-koblenz.de> Signed-off-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Tested-by: Martin Peres <martin.peres@linux.intel.com> Tested-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
