[RFC PATCH 0/4] bus: ti-sysc: Add generic enable/disable & PRUSS

Hi Tony,

Non legacy modules will rely on generic enable/disable functions.

I had to disable usb_otg_ss3 and 4 on am57xx idk to be able to boot.
It is explicitly stated in TRM to not use USB3 and 4 on AM57xx, and
I haven't seen any dra7 based board using them so let's keep it disabled.

Handle the PRU-ICSS type as it needs some special handling especially
during suspend/resume.


Roger Quadros (4):
ARM: dts: dra7: Keep usb_otg_ss3 and usb_otg_ss4 disabled
bus: ti-sysc: Add generic enable/disable functions
bus: ti-sysc: Add support for PRU-ICSS type
bus: ti-sysc: Ensure PRU-ICSS doesn't break suspend/resume
