This driver currently only supports legacy platform data probe. This change adds device tree support and gets rid of platform data probe code since no one is actually using mpr121 platform data in the mainline. The device tree property parsing code is based on the work of atmel_captouch driver. Signed-off-by:

This driver reports input events on their interrupts which are triggered by the sensor's status register changes. But only single bit change is reported in the interrupt handler. So if there are multiple bits are changed at almost the same time, other press or release events are ignored. This fixes it by detecting all changed bits in the status register. Signed-off-by:

This driver reports misc scan input events on the sensor's status register changes. But the event capability for them was not set in the device initialization, so these events were ignored. This change adds the missing event capability. Signed-off-by:

msleep(1~20) may not do what the caller intends, and will often sleep longer (~20 ms actual sleep for any value given in the 1~20ms range). This is not the desired behaviour for many cases like device resume time, device suspend time, device enable time, retry logic, etc. Thus, change msleep to usleep_range for precise wakeups.

The order of endpoints is well defined on official Xbox pads, but we have found at least one 3rd-party pad that doesn't follow the standard ("Titanfall 2 Xbox One controller" 0e6f:0165). Fortunately, we get lucky with this specific pad because it uses endpoint addresses that differ only by direction. We know that there are other pads out where this is not true, so let's go ahead and fix this. Signed-off-by:Cameron Gutman <aicommander@gmail.com> Signed-off-by:

We rely on the result of scanning PNP bus for keyboard and mouse devices to decide whether we should continue initialization of i8042 driver or not, so the probes can not be asynchronous. Also, it is not a good idea to unbind either of the PNP devices while i8042 is running, so let's disable bind/unbind for the PNP drivers through sysfs and rely on i8042 cleaning after itself properly. User can still unbind and rebind entire i8042 and that will take care of PNP drivers as well. Reviewed-by:

Jingkui Wang authored
We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. 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. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us. Signed-off-by:

Semantics of NR_IRQS is different on machines with SPARSE_IRQ option disabled or enabled, in the latter case IRQs are allocated starting at least from the value specified by NR_IRQS and going upwards, so the check of (irq >= NR_IRQ) to decide about an error code returned by platform_get_irq() is completely invalid, don't attempt to overrule irq subsystem in the driver. The change fixes lpc32xx_keys driver initialization on boot: lpc32xx_keys 40050000.key: failed to get platform irq lpc32xx_keys: probe of 40050000.key failed with error -22 Signed-off-by:

The HID implementation of RMI4 provides the data during the interrupt (in the input report). We need to provide a way for this transport driver to provide the attention data while calling an IRQ. We use a fifo in rmi_core to not lose any incoming event. Signed-off-by:

Dennis Wassenberg authored
First check if there are data available passed by the transport device. If data available use these data. If there are no data available try to read the rmi block if dsata are passed this way. This is the way the other rmi function handlers will do this. This patch is needed on HID devices because the firmware reads F03 data registers and adds them to the HID attention report. Reading those registers from the driver after the firmware read them will result in invalid data. Reviewed-by:

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. Signed-off-by:

This partially reverts commit 29fd0ec2 ("Input: synaptics-rmi4 - add support for F34 device reflash") irq_mutex should be used only to protect data->current_irq_mask, not preventing incoming input to be processed while the upgrade of the firmware is happening. We can simply disable the irqs when we don't want them to interfere with the upgrade process. Tested on S7300 and S7800 (with F34 v7 patch added) Signed-off-by:

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. Please note that this change is untested, as I do not have this piece of hardware. Testers are welcome! Signed-off-by:

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. Reviewed-by:
