Jingkui Wang bc682a50a0 Input: drv260x - remove OF dependency
As the driver is using generic device properties, it should work
properly when CONFIG_OF is turned off. This patch removes the
ifdef CONFIGOF and make sure the driver always have of_match_table.

Jingkui Wang 34888602eb Input: drv260x - use generic device properties
Update driver drv260x to use generic device properties so that it can be
used on non-DT systems. We also remove platform data as generic device
properties work on static board code as well.

Let's introduce a temporary for "client->dev" is probe() as we use
it quite a few times and "dev" is shorter.

Jingkui Wang 5a8a6b89c1 Input: drv260x - fix input device's parent assignment
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.

Nariman Poushin 8019ff6cfc regmap: Use reg_sequence for multi_reg_write / register_patch
Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.

This also updates all the clients of multi_reg_write/register_patch.

Uwe Kleine-König ea0afac450 Input: improve usage of gpiod API
Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for
output. Simplify drivers accordingly.

Note that in the case of the drv260x driver error checking is more
strict now because -ENOSYS is reported to the caller now. But this
should only be returned if GPIOLIB is disabled which shouldn't happen as
the driver depends on GPIOLIB.

Dan Murphy 7132fe4f56 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.
