Input: drv260x - fix initializing overdrive voltage

2018-05-23T01:36:36Z

[ Upstream commit 74c82dae6c474933f2be401976e1530b5f623221 ] We were accidentally initializing haptics->rated_voltage twice, and did not initialize overdrive voltage. Acked-by: Dan Murphy Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: drv260x - fix input device's parent assignment

2017-01-13T01:56:57Z

[ Upstream commit 5a8a6b89c15766446d845671d574a9243b6d8786 ] 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.

Input: drv260x - remove wrong and unneeded drv260x-haptics modalias

2015-02-01T19:21:24Z

This is a I2C driver, so it's wrong to use platform prefix for the modalias. We have all needed i2c aliases coming form MODULE_DEVICE_TABLE, so let's remove the wrong and unneeded drv260x-haptics modalias. Signed-off-by: Axel Lin Signed-off-by: Dmitry Torokhov

Input: misc - use __maybe_unused instead of ifdef around suspend/resume

2014-11-02T07:10:06Z

Use __maybe_unused instead of ifdef guards around suspend/resume functions, in order to increase build coverage and fix build warnings. Signed-off-by: Jingoo Han Signed-off-by: Dmitry Torokhov

Input: drv260x - add check for ERM mode and LRA Libraries

2014-08-26T22:42:03Z

Add a check to ensure that LRA libraries are not mixed with the ERM mode. If ERM mode and the Library is empty "OR" the LRA library then exit, as the LRA and empty libraries are not applicable for the ERM actuator. Signed-off-by: Dan Murphy Signed-off-by: Dmitry Torokhov

Input: drv260x - remove unused defines

2014-08-26T22:42:02Z

Removing some #defines that are not and should never be used pertaining to I2C. Removing: define DRV260X_ALLOWED_R_BYTES 25 define DRV260X_ALLOWED_W_BYTES 2 define DRV260X_MAX_RW_RETRIES 5 define DRV260X_I2C_RETRY_DELAY 10 Signed-off-by: Dan Murphy Signed-off-by: Dmitry Torokhov

Input: drv260x - add TI drv260x haptics driver

2014-08-20T05:19:28Z

Add the TI drv260x haptics/vibrator driver. This device uses the input force feedback to produce a wave form to driver an ERM or LRA actuator device. The initial driver supports the devices real time playback mode. But the device has additional wave patterns in ROM. This functionality will be added in future patchsets.
