Subject: [PATCH v2 08/19] dt-bindings: clk: axg-clkc: expose all clock ids
Due to a policy change in clock ID bindings handling, expose
all the "private" clock IDs to the public clock dt-bindings
to move out of the previous maintenance scheme.
This refers to a discussion at [1] & [2] with Krzysztof about
the issue with the current maintenance.
It was decided to move every axg-clkc ID to the public clock
dt-bindings headers to be merged in a single tree so we
can safely add new clocks without having merge issues.
