This patchset implements changes based on the synaptics-rmi4 branch of
Dmitry's input tree. The base for the patchset is Dmitry's commit
0af25383d395fb5ece54b79d12d06138bf8b9836 from 2012-11-28. It supersedes
our previous patch submission from 2012-12-18.
Overall this patchset implements the following changes with respect to
the Dmitry's 2012-11-28 commit:
* updates to Dmitry's RMI4_CORE structure from his 2012-11-28 patches.
This tries to maintain the same approach as Dmitry's implementation, but
we had to move away from using the bus probe() routine, since it wasn't
possible for that routine to readily determine if it had a struct driver() for
an RMI4 sensor or an RMI4 device. Otherwise, we've stuck close to Dmitry's
work, which has tidied things up nicely.
* We've renamed the structures rmi_function_handler to rmi_function_driver and
rmi_device to rmi_function_dev, mainly because they actually were being treated
as drivers and devices for individual RMI4 functions, and the previous
terminology was somewhat confusing.
* Changed a bunch of bools to u32 to support standard debugfs macros. Moved
almost all the debugfs and sysfs handling out of these files into their own
modules, simplifying the core functionality of the driver. Once the core is
stable, we can look into adding modules to support the debug/control
* Many other bools were changed to u8, per Dmitry's request.
* Trivial - file copyright header is updated to be more in line with the rest
of the files under ./input.
We've broken this patch into 6 parts, as follows:
01 - public header file
02 - core sensor and bus implementation
03 - I2C physical layer driver
04.05 - drivers for individual RMI functions
Hopefully this is the last time we'll have wide-ranging structural changes in
the driver code, and future patchsets can be much smaller and confined to
one or two areas of interest.
Comments and other feedback on this driver are welcomed.
