commit 5a8a6b89c1 upstream.
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.

commit eda5ecc0a6 upstream.
The trigger delay algorithm that converts from microseconds to
the register value looks incorrect. According to most of the PMIC
documentation, the equation is
delay (Seconds) = (1 / 1024) * 2 ^ (x + 4)
except for one case where the documentation looks to have a
formatting issue and the equation looks like
delay (Seconds) = (1 / 1024) * 2 x + 4
Most likely this driver was written with the improper
documentation to begin with. According to the downstream sources
the valid delays are from 2 seconds to 1/64 second, and the
latter equation just doesn't make sense for that. Let's fix the
algorithm and the range check to match the documentation and the
downstream sources.

This driver allows userspace to receive notification when client
specified key combinations are pressed.
The client opens /dev/keychord and writes a list of keychords
for the driver to monitor.
The client then reads or polls /dev/keychord for notifications.
A client specified ID for the keychord is returned from read()
when a keychord press is detected.

Some encoders have both outputs low in stable states, others also have
a stable state with both outputs high (half-period mode) and some have
a stable state in all steps (quarter-period mode). The driver used to
support the former states and with this change it can also support the
later.
This commit also deprecates the 'half-period' property and introduces
a new property 'steps-per-period'. This property specifies the
number of steps (stable states) produced by the rotary encoder
for each GPIO period.

Add DA9062 OnKey support into the existing DA9063 OnKey driver component by
using generic access tables for common register and bit mask definitions.
The following change will add generic register and bit mask support to the
DA9063 OnKey.
The following alterations have been made to the DA9063 OnKey:
- Addition of a da906x_chip_config structure to hold all
generic registers and bitmasks for this type of OnKey component.
- Addition of an struct of_device_id table for DA9063 and DA9062
defaults
- Refactoring functions to use struct da9063_onkey accesses to generic
registers/masks instead of using defines from registers.h
- Re-work of da9063_onkey_probe() to use of_match_node() and
dev_get_regmap() to provide initialisation of generic registers and
masks and access to regmap

However during initial write of the uinput structure that contains min/max
