14   The RK3288 clock controller generates and supplies clocks to various
18   A revision of this SoC is available: rk3288w. The clock tree is a bit
19   different so another dt-compatible is available. Noticed that it is only
23   Each clock is assigned an identifier and client nodes can use this identifier
24   to specify the clock which they consume. All available clocks are defined as
25   preprocessor macros in the dt-bindings/clock/rk3288-cru.h headers and can be
26   used in device tree sources. Similar macros exist for the reset sources in
30   that they are defined using standard clock bindings with following
