Following are the DTS used:- The device tree documentation for the keystone machines are located at Documentation/devicetree/bindings/arm/keystone/keystone.txt Known issues & workaround ------------------------- Some of the device drivers used on keystone are re-used from that from DaVinci and other TI SoCs. These device drivers may use clock APIs directly. Some of the keystone specific drivers such as netcp uses run time power management API instead to enable clock. As this API has limitations on keystone, following workaround is needed to boot Linux. Add 'clk_ignore_unused' to the bootargs env variable in u-boot. Otherwise clock frameworks will try to disable clocks that are unused and disable the hardware. This is because netcp related power domain and clock domains are enabled in u-boot as run time power management API currently doesn't enable clocks for netcp due to a limitation. This workaround is expected to be removed in the future when proper API support becomes available. Until then, this work around is needed.
