Nuvoton Poleg BMC NPCM7XX contains an integrated clock controller, which
|
|
generates and supplies clocks to all modules within the BMC.
|
|
|
|
External clocks:
|
|
|
|
There are six fixed clocks that are generated outside the BMC. All clocks are of
|
|
a known fixed value that cannot be changed. clk_refclk, clk_mcbypck and
|
|
clk_sysbypck are inputs to the clock controller.
|
|
clk_rg1refck, clk_rg2refck and clk_xin are external clocks suppling the
|
|
network. They are set on the device tree, but not used by the clock module. The
|
|
network devices use them directly.
|
|
|
|
All available clocks are defined as preprocessor macros in:
|
|
dt-bindings/clock/nuvoton,npcm7xx-clock.h
|
|
and can be reused as DT sources.
