From a885f0fe209f262efa2c1cac9278a5774e5f7a80 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 22 Feb 2018 14:03:48 -0800 Subject: bus: ti-sysc: Handle some devices in omap_device compatible way Now that ti-sysc can manage child devices, we must also be backwards compatible with the current omap_device code. With omap_device, we assume that the child device manages the interconnect target module directly. The drivers needing special handling are the ones that still set pm_runtime_irq_safe(). In the long run we want to update those drivers as otherwise they will cause problems with genpd as a permanent PM runtime usage count is set on the parent device. We can handle omap_device these devices by improving the ti-sysc quirk handling to detect the devices needing special handling based on register map and revision register if usable. We also need to implement dev_pm_domain for these child devices just like omap_device does.
