From 7132fe4f568721cbd5d9bce5a8a71556e9bc45b4 Mon Sep 17 00:00:00 2001 From: Dan Murphy Date: Sun, 17 Aug 2014 09:24:26 -0700 Subject: Input: drv260x - add TI drv260x haptics driver 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.
