The CLK_RCAR_GEN3 registers two subdrivers, clk_gen3 and rst_gen3. The former depends on the clock framework, which is always enabled in this context of clock framework driver, while the later depends on reset framework which may not always be enabled.
Ensure the reset framework is also always enabled to prevent inobvious early boot time bind failure of the CPG driver, which leads to system showing no activity and is difficult to debug.
Note that one possible approach to debug this is to use CONFIG_DEBUG_UART and add debug printascii()s into the drivers/clk/renesas/clk-rcar-gen3.c .
