Hi Dariusz, I have a Dell XPS 12-9Q33 and two U2414Hb Dell displays, all DP 1.2 MST compatible.
Using your instructions, I installed the new kernel and intel driver. Daisy chaining the two displays to my laptop DOES NOT work. With this kernel no external display works anymore. Moreover, my wireless network controller is now no longer working. Even though it's listed in lspci as a 'Network controller: Intel Corporation Wireless 7260 (rev 6b)', rfkill list shows nothing. Also, the touchscreen of my laptop stopped working with this kernel. It's no longer in the output of xinput list, which should show 'ATML1000:00 03EB:842F'. Lastly, my brightness keys don't work anymore. When I reboot with official kernel 3.13, everything works again. Of course, except for MST. Can you perhaps explain what's going on?
