-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.
-
-SoC families:
-
-- Keystone 2 generic SoC:
-   compatible = "ti,keystone"
-
-SoCs:
-
-- Keystone 2 Hawking/Kepler
-   compatible = "ti,k2hk", "ti,keystone"
-- Keystone 2 Lamarr
-   compatible = "ti,k2l", "ti,keystone"
-- Keystone 2 Edison
-   compatible = "ti,k2e", "ti,keystone"
-- K2G
-   compatible = "ti,k2g", "ti,keystone"
-
-Boards:
--  Keystone 2 Hawking/Kepler EVM
-   compatible = "ti,k2hk-evm", "ti,k2hk", "ti,keystone"
-
--  Keystone 2 Lamarr EVM
-   compatible = "ti,k2l-evm", "ti, k2l", "ti,keystone"
-
--  Keystone 2 Edison EVM
-   compatible = "ti,k2e-evm", "ti,k2e", "ti,keystone"
-
--  K2G EVM
-   compatible = "ti,k2g-evm", "ti,k2g", "ti-keystone"
-
--  K2G Industrial Communication Engine EVM
-   compatible = "ti,k2g-ice", "ti,k2g", "ti-keystone"
