Add the ability to selectively enable over current protection
(OCP) for LVS and MVS type PMIC voltage switches. OCP is used to
automatically disable the output of a PMIC switch in hardware when
the load on the switch becomes too large.
The sequence used when enabling a switch when OCP is desired is as
follows:
1. Disable OCP.
2. Enable the switch.
3. Wait for ocp_enable_time microseconds.
4. Enable OCP.
This sequence is used to ensure that sufficient time is allowed
for inrush current to subside so that a false OCP event is not
triggered. The delay time is board specific.

Specify the SSBI test register address for each of the voltage
switches in PMIC 8018, 8038, and 8921 core drivers. This will
allow for future handling of over current protection (OCP) in
the pm8xxx-regulator driver.
Also define the OCP IRQs associated with each of the switches
on these PMICs.

The atmel_mxt_ts driver manipulates the touch coordinates
if they are < 1024. In cases when the display < 1024 and
virtual key area > 1024, there is a problem in reporting
the coordinates for the virtual key area. Add new pdata
variables which can handle this.

Allowing a lock to be asynchronously released while a handle

purpose anyway. Handles now hold an attached lock until they

There is a possibility that 2 or more clients can use the same
channel, one as producer and the other(s) as sink.
The slim_query_ch API gives the ability for a client to specify
channel number it needs to use.
Reference counting is used to make sure channel is not deallocated
until the last caller deallocates it.
Another counter (def) is used to keep track of channel definition and
removal. Channel definition is sent to hardware when the producer
and/or consumer(s) connects ports to the channel. Channel is only
removed when all clients indicate they want to remove channel.

Add kernel API to read TSENS temperature for clients
in the kernel space. Currently the TSENS driver only
supports reading the TSENS temperature from the
thermal sys.
Split the TSENS initialization into two parts.
First is to perform the initial calibration that is
used to convert the raw ADC code to Degrees Celcius
and initialize the TSENS HW. Second is to register the
TSENS driver to the linux thermal framework and create
the temperature zones that will be accessed by the
Thermal daemon to set thresholds, read the temperature
and receive notifications.
