Hi!
now I'm testing 4.2-rc2 release and rtc is working:
[ 27.426055] omap_i2c 48072000.i2c: controller timed out
[ 28.723358] twl_rtc 48070000.i2c:twl@48:rtc: Power up reset detected.

There is still some i2c time out line and some reset detected, but
driver loads fine.
But problem with touchscreen tsc2005 and wifi wl1251 is still there :-(
Drivers are compiled as external .ko modules.
Plus I see new problem with bq2415_charger :-(
