2016-12-25ktime: Cleanup ktime_set() usageThomas Gleixner
ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.

2016-12-19Input: i8042 - Trust firmware a bit more when probing on X86Dmitry Torokhov
The error message "Can't read CTR while initializing i8042" appears on Cherry Trail-based devices at each boot time: i8042: PNP: No PS/2 controller found. Probing ports directly. i8042: Can't read CTR while initializing i8042 i8042: probe of i8042 failed with error -5 This happens because we historically do not trust firmware on X86 and, while noting that PNP does not show keyboard or mouse devices, we still charge ahead and try to probe the controller. Let's relax this a bit and if results of PNP probe agree with the results of platform initialization/quirks conclude that there is, in fact, no i8042. While at it, let's avoid using x86_platform.i8042_detect() and instead abort execution early if platform indicates that it can not possibly have i8042 (x86_platform.legacy.i8042 equals X86_LEGACY_I8042_PLATFORM_ABSENT).

As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later.

2016-11-30Input: imx6ul_tsc - convert int to u32Guy Shapiro
The code uses of_property_read_u32 and expects positive values. However, the values are stored in signed int variables. Additionally, the registers values are also stored in signed variables without a good reason (readl/writel expect u32). The only time this caused a real bug was in the new average-samples property, in which the property is numerically compared and implicitly expected to be positive. I believe it's better to change all the properties and registers to u32, for consistency and warnings reduction.

2016-11-30Input: drv2667 - fix misuse of regmap_update_bitsFlorian Vaussard
Using regmap_update_bits(..., mask, 1) with 'mask' following (1 << k) and k greater than 0 is wrong. Indeed, _regmap_update_bits will perform (mask & 1), which results in 0 if LSB of mask is 0. Thus the call regmap_update_bits(..., mask, 1) is in reality equivalent to regmap_update_bits(..., mask, 0). In such a case, the correct use is regmap_update_bits(..., mask, mask). This driver is performing such a mistake with the DRV2667_STANDBY mask, which equals (1 << 6). Fix the driver to make it consistent with the API, and fix the alignment problem at the same time.

Using regmap_update_bits(..., mask, 1) with 'mask' following (1 << k) and k greater than 0 is wrong. Indeed, _regmap_update_bits will perform (mask & 1), which results in 0 if LSB of mask is 0. Thus the call regmap_update_bits(..., mask, 1) is in reality equivalent to regmap_update_bits(..., mask, 0). In such a case, the correct use is regmap_update_bits(..., mask, mask). This driver is performing such a mistake with the DRV2665_STANDBY mask, which equals BIT(6). Fix the driver to make it consistent with the API, and fix the alignment problem at the same time. Please note that this change is untested, as I do not have this piece of hardware. Testers are welcome!

2016-11-28Input: ALPS - clean up code for SS5 hardwarePaul Donohue
The return value of alps_get_pkt_id_ss4_v2() should really be "enum SS4_PACKET_ID", not "unsigned char". Correct this. Also, most of the Alps SS5 (SS4 v2) packet byte parsing code is implemented using macros, but there are a few places where bytes are directly manipulated in alps.c. For consistency, migrate the rest of these to macros.

2016-11-28Input: ALPS - fix TrackStick support for SS5 hardwarePaul Donohue
The current Alps SS5 (SS4 v2) code generates bogus TouchPad events when TrackStick packets are processed. This causes the xorg synaptics driver to print "unable to find touch point 0" and "BUG: triggered 'if (priv->num_active_touches > priv->num_slots)'" messages. It also causes unexpected TouchPad button release and re-click event sequences if the TrackStick is moved while holding a TouchPad button. This commit corrects the problem by adjusting alps_process_packet_ss4_v2() so that it only sends TrackStick reports when processing TrackStick packets.

2016-11-27Input: xpad - fix Xbox One rumble stopping after 2.5 secsCameron Gutman
Unlike previous Xbox pads, the Xbox One pad doesn't have "sticky" rumble packets. The duration is encoded into the command and expiration is handled by the pad firmware. ff-memless needs pseudo-sticky behavior for rumble effects to behave properly for long duration effects. We already specify the maximum rumble on duration in the command packets, but it's still only good for about 2.5 seconds of rumble. This is easily reproducible running fftest's sine vibration test. It turns out there's a repeat count encoded in the rumble command. We can abuse that to get the pseudo-sticky behavior needed for rumble to behave as expected for effects with long duration. By my math, this change should allow a single ff_effect to rumble for 10 minutes straight, which should be more than enough for most needs.

F54 diagnostics report functions provide data based on the number of enabled rx and tx electrodes, which is not identical to the number of electrodes reported with F54:Query0 and F54:Query1. Those values report the number of supported electrodes, not the number of enabled electrodes. The number of enabled electrodes can be determined by analyzing F55:Ctrl1 (sensor receiver assignment) and F55:Ctrl2 (sensor transmitter assignment). Propagate the number of enabled electrodes from F55 to F54 to avoid corrupted output if not all electrodes are enabled. Fixes: 3a762dbd5347 ("[media] Input: synaptics-rmi4 - add support for F54 ...")

2016-11-17Input: gpio_keys - set input direction explicitlySudeep Holla
Commit 700a38b27eef ("Input: gpio_keys - switch to using generic device properties") switched to use generic device properties for GPIO keys and commit 5feeca3c1e39 ("Input: gpio_keys - add support for GPIO descriptors") switched from legacy GPIO numbers to GPIO descriptors. Previously devm_gpio_request_one was explicitly passed GPIOF_DIR_IN flag to set the GPIO direction as input. However devm_get_gpiod_from_child doesn't have such provisions and hence fwnode_get_named_gpiod can't set it as input. This breaks few platforms with the following error: " gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ unable to lock HW IRQ <n> for IRQ genirq: Failed to request resources for POWER (irq <x>) on irqchip gpio_keys: Unable to claim irq <x>; error -22 gpio-keys: probe failed with error -22 " This patch fixes the issue by setting input direction explicitly for gpio lines described by generic properties.
