Update the name associated with the RCC drivers to avoid duplicated name with the driver name. With this patch the traces displayed with log macro provide a correct device name. The rcc device name before the patch is: Class Index Probed Driver Name ----------------------------------------------------------- root 0 [ + ] root_driver root_driver simple_bus 0 [ + ] simple_bus |-- soc (...) nop 0 [ + ] stm32-rcc | |-- rcc@50000000 clk 0 [ + ] stm32mp1_clk | | |-- stm32mp1_clk reset 0 [ + ] stm32_rcc_reset | | `-- stm32_rcc_reset And they become: (...) nop 0 [ + ] stm32-rcc | |-- rcc@50000000 clk 0 [ + ] stm32mp1_clk | | |-- rcc@50000000 reset 0 [ + ] stm32_rcc_reset | | `-- rcc@50000000 The traces is correct: stm32mp1_clk rcc@stm32mp1_clk: ..... => stm32mp1_clk rcc@50000000: .....
