I have created "sentelic" branch here:
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git
I fetched the latest version of the driver off the sourceforge page and
used it as the baseline.
Thank you. I'm reading through the differences. Looks good to me so far.
The idea is to implement full absolute packet support and not rely on
relative packets because users will expect Synaptics X driver work with
this device as it works with all other touchpads (Synaptics, ALPS,
Elantec, BCM, appletouch).
I can understand that; however, absolute coordinates returned by
current FSP hardware isn't suitable for cursor movement, which makes
relative packet necessary if you want to have a functional hardware.
BTW, I have a few questions regarding protocol:
What is 'arc', x1_g, x2_g, y1_g, y2_g in the absolute packet data?
Those are obsoleted information which used to represent finger tracks.
Hi, Dmitry,
Following are a few changes based on the sentelic branch you've created:
- Returning EIO instead of ENODEV when fsp_page_reg_read() failed;
- Reverting onpadicon and pktfmt sysfs node to world writable as userland
application needs to write it without root privilege;
- Removing unused variables from fsp_hw_state.
