[RFC/RFT PATCH 4/4] [debug] ARM: am335x: illustrate hwstamp

[Grygorii Strashko]

This patch allows to test CPTS HW_TS_PUSH functionality on am335x boards

below sequence of commands will enable Timer7 to trigger 1sec
periodic pulses on CPTS HW4_TS_PUSH input pin:

 # echo 10 > /sys/class/pwm/pwmchip0/pwm0/period
 # echo 5 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
 # echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable
 # ./ptp/testptp -e 10 -i 3

This patch allows to test CPTS HW_TS_PUSH functionality on am335x boards

below sequence of commands will enable Timer7 to trigger 1sec
periodic pulses on CPTS HW4_TS_PUSH input pin:

 # echo 10 > /sys/class/pwm/pwmchip0/pwm0/period
 # echo 5 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
 # echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable
 # ./ptp/testptp -e 10 -i 3
