[PATCH v1 1/1] dts: bindings: trivial clock bindings doc fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




fix a typo in the "clock specifiers" discussion,
clarify that clock specifiers (the integer cells
part that goes with the phandle) may be empty

this may sound like nit picking, but from an earlier explanation by Mark
Rutland I learned that a reference always consists of a phandle and a
specifier, that the specifier is the sequence of integer cells that
accompany the phandle, and that the phandle "by intuition might be
expected to" be part of the specifier but specificly is not (and shall
not, to keep the existing documentation consistent)

since I was fixing the typo, and had the above information, I could not
resist but had to add the "may be zero cells" detail in bypassing

found no other issue in this file -- don't worry, won't emit an endless
stream of tiny trivial changes, this one is all there is :)

@@ -5,7 +5,7 @@ Sources of clock signal can be represented by any node in the device
 tree.  Those nodes are designated as clock providers.  Clock consumer
 nodes use a phandle and clock specifier pair to connect clock provider
 outputs to clock inputs.  Similar to the gpio specifiers, a clock
-specifier is an array of one more more cells identifying the clock
+specifier is an array of zero, one or more cells identifying the clock
 output on a device.  The length of a clock specifier is defined by the
 value of a #clock-cells property in the clock provider node.
