TI Keystone Platforms Device Tree Bindings
|
||||
-----------------------------------------------
|
||||
|
||||
Boards with Keystone2 based devices (TCI66xxK2H) SOC shall have the
|
||||
following properties.
|
||||
|
||||
Required properties:
|
||||
- compatible: All TI specific devices present in Keystone SOC should be in
|
||||
the form "ti,keystone-*". Generic devices like gic, arch_timers, ns16550
|
||||
type UART should use the specified compatible for those devices.
