Subject: [PATCH v2 1/3] dt-bindings: clock: gcc-sdm845: add sdm670 global clocks
The Snapdragon 670 clocks will be added into the sdm845 gcc driver. Most
of the new clocks, GDSCs, and resets already have reserved IDs but there
are some resources that don't. Add the new clock and extra BCR from
Snapdragon 670 and document the differences between the SoC parent clocks.
Signed-off-by: Richard Acayan <mailingradian@...il.com>
