The input pull request for the Linux 3.9 kernel
has went in and it supports new touchpad drivers and more.
The two new touchpad drivers for Linux 3.9 are for the Cypress APA I2C Trackpad and Cypress PS/2 Touchpad. The Cypress All Points Addressable I2C Trackpad is the input pad used most notably by the Samsung Series 5 Chromebook.
Pertaining to the Linux 3.9 kernel supporting Google's Goldfish
, there's also a new input driver for this emulator.
More details on the input updates for Linux 3.9 can be found within the merge request
