I can confirm that after enabling CONFIG_PINCTRL_CHERRYVIEW and using the patch: https://bugzilla.kernel.org/show_bug.cgi?id=108481 the touchpad is working on my aspire R3-131T (kernel 4.4.0). The SD card has problem indeed, so if a patch for it is available please let me know and I will test it. About Leap 42.1 it would be great if not only the touchpad get fixed, but also if the support for the Braswell chip can be improved.
