Subject[PATCH net-next v2 05/10] ARM: dts: keystone-clocks: add input fixed clocks
Date
Add set of fixed, external input clocks definitions for TIMI0, TIMI1,
TSREFCLK clocks. Such clocks can be used as reference clocks for some HW
modules (as cpts, for example) by configuring corresponding clock muxes.
For these clocks real frequencies have to be defined in board files.
