Eneabling UART1 on BBB Kernel 3.19

Hi Guys,

I have a problem.
What I have done so far for enabling the UART1.
Downloaded, dtb-rebuilder for Kernel 19, outcommented the two lines for tty2, make, make install and reboot.

After reboot I have those results:

cat /sys/kernel/debug/pinctrl/44e10800.pinmux/pingroups
pin 84 (44e10950.0): 48024000.serial (GPIO UNCLAIMED) function pinmux_uart2_pins group pinmux_uart2_pins
pin 85 (44e10954.0): 48024000.serial (GPIO UNCLAIMED) function pinmux_uart2_pins group pinmux_uart2_pins

dmesg |grep serial says:
[ 2.321838] omap8250 44e09000.serial: ttyS0 at MMIO 0x44e09000 (irq = 154, base_baud = 3000000) is a 8250
[ 2.340061] omap8250 48024000.serial: ttyS2 at MMIO 0x48024000 (irq = 155, base_baud = 3000000) is a 8250

Uname -a:
Linux arm 3.19.0-rc31.2 #2 Fri Apr 17 08:00:32 UTC 2015 armv7l GNU/Linux

I think the pins are muxed correctly. But I thought the name for UART is ttyO2 for UART2 and not ttyS2.
Has it changed with the Kernel Upgrade?? Or do I have to activate it somehow?

Thank you in advance!!

greetings
Benjamin

It's been changed as of v3.19.x
