tslib: ts_calibrate utility on Beaglebone Black.

[Emran Caan]

Hi Forum,
I am using a recent kernel from the branch 'remotes/origin/am33x-v4.15'
for the BBB from RCN site, the detail as follow:

kernel details
======================================
ubuntu@arm:~$ uname -a
Linux arm 4.15.0-bone2.1 #1 Tue Jan 30 11:48:09 GMT 2018 armv7l armv7l armv7l GNU/Linux

ts_setup: No such file or directory

RAM: 47MiB / 491Mi
============ Eof kernal details =================

IS ANYONE has clue how to get it work, please?
I read Hartley Sweeten blog but modifying and rebuilding an entire OS is not in my interest.
But I assume the following patch has been merged into
the stated branch ('remotes/origin/am33x-v4.15')?
