Hi,

during change from 3.8 kernel to 4.14 I struggled with an issue regarding 
PWMSS accessed by PRU.
On old kernel I load overlay am33xx_pwm to activate the PWMSS.
I verified this with: devmem2 0x483000000 (base address of PWMSS0)

With 4.14 kernel I get 'bus error' when I execute same 'devmem2 0x483000000'
Also PRU have no access to PWMSS.

But loading the am33xx_pwm seems succesful, at least the sysfs folder is 
populated with pwm folders.

How can the PRU gain access to PWMSS?

Best regards
