STM32_DT_CLOCKS was designed to take a device tree node label name as argument: STM32_DT_CLOCKS(uart1) Change its implementation to take a node identifier instead: STM32_DT_CLOCKS(DT_NODELABEL(uart1)). This make its usage more flexible since the argument can now be extracted from other DT macros such as DT_PARENT. Then, the following can be done: STM32_DT_CLOCKS(DT_PARENT(child_node_label)). Since it is now possible implement STM32_DT_INST_CLOCKS using STM32_DT_CLOCKS. Finally, update existing STM32_DT_CLOCKS users and convert STM32_INST_CLOCK_INFO users to STM32_CLOCK_INFO.
