SPI device file didn't create. ls /dev/spi* : No such file or directory

Hello All,

I am new to BBB.

I am using below kernel version on my BBB.

uname -a

Linux arm 4.4.12-ti-r30 #1 SMP Thu Jun 9 07:50:17 UTC 2016 armv7l armv7l armv7l GNU/Linux

And i was able to load the SPI ports successfully as shown below.
cat /sys/devices/platform/bone_capemgr/slots
0: PF---- -1
1: PF---- -1
2: PF---- -1
3: PF---- -1
4: P-O-L- 0 Override Board Name,00A0,Override Manuf,BB-SPIDEV0
5: P-O-L- 1 Override Board Name,00A0,Override Manuf,BB-SPIDEV1

But SPI device file could not created under ls -l /dev/spi*
ls /dev/spi*
ls: cannot access ‘/dev/spi*’: No such file or directory

Please help me on the above issue, to create the SPI device file.

Thank you.
