Can't see patch pins in pingroup

Hello all,

I trying patch file am335x-boneblack.dts (http://git.ti.com/ti-linux-kernel/ti-linux-kernel/blobs/ti-lsk-linux-4.4.y/arch/arm/boot/dts/am335x-boneblack.dts) in yocto in order to using pru on my BBB. However I can’t see any change in /sys/kernel/debug/pinctrl/44e10800.pinmux/pingroups. Pin groups looks like (still same):

However tree in /sys/devices/platform/ocp/ looks as I expected (reflect patch):
