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.
