So finally we can use HID sensor hub over I2C.
Did you try with any I2C sensor hub?
Yes, we have I2C HID sensor hub here and I tested with it. However, I'm not
that familiar how it should be used except that I can see the
The ChromeOS Embedded Controller (EC) is an Open Source EC implementation
used on ARM and Intel Chromebooks. Current implementations use a Cortex-M3
connected on a bus (such as I2C, SPI, LPC) to the AP. A separate interrupt
line is used to indicate when the EC needs service.
Functions performed
Use the key-matrix layer to interpret key scan information from the EC
and inject input based on the FDT-supplied key map. This driver registers
itself with the ChromeOS EC driver to perform communications.
Additional FDT bindings are provided to specify rows/columns and the
auto-repeat
We now have a binding which adds two parameters to the matrix keypad DT
node. This is separate from the GPIO-driven matrix keypad binding, and
unfortunately incompatible, since that uses row-gpios/col-gpios for the
row and column counts.
So the easiest option here is to provide a function for
