ubuntu 16.04 - kernel 4.6 work, 4.7 don't work on bay trail Z3736F - PIPOX9

Hi on PIPO X9 (bay trail Z3736F) on Ubuntu Xenial 16.04 with rtl8723bs and rtl8723bs_bt
I compile kernel 4.6.0, 4.6.3 and 4.7rc1 with known patch for rfkill-gpio - OBDA8723, bluetooth work very good. But on 4.7 series I compile kernels 4.7rc6 4.7rc7, 4.7.0 release with patch for rfkill-gpio - OBDA8723, bluetooth don't work and show different tty's and rfkill list - don't show bluetooth rfkill.
Params below:

4.6.0, 4.6.3, 4.7rc1 - Work params with patch for rfkill-gpio - OBDA8723,
dmesg | grep tty
report ttyS4 and ttyS5, start_bt report ttyS4 - and hciconfig - show dev properties.
rfkill list - show bluetooth rfkill and wlan rfkill
(off topic: on 4.7rc1 I can't compile wifi rtl8723 (hadess) show: rtw_cmd.o no rules to make.etc, but on 4.6.3 is OK)

4.7rc6 4.7rc7, 4.7.0 release don't work with patch for rfkill-gpio - OBDA8723,
dmes | grep tty
report different tty's - ttyS1 and ttyS2 but on 4.6.3 or 4.7rc1 it was ttyS4 and ttyS5
when start _bt report ttyS1, but full report end with: Realtek Bluetooth ERROR: H5 sync timed out
hciconfig - don't show anything, and rfkill list - don't show bluetooth rfkill !!!

Maybe some one know why newer kernel make different tty and how to change it in kernel, maybe it will start to work then or some other solution?
Off topic: maybe someone know how to compile hadess rtl8723 on 4.7rc1 to by pass error in make: error rtw_cmd.o no rules to make ....

Thanks
