Alternatively, the call to rcar_gen2_clocks_init() in
arch/arm/mach-shmobile/setup-rcar-gen2.c:rcar_gen2_timer_init()
can be protected temporarily by

    #if defined(CONFIG_R8A7790) || ... || defined(CONFIG_R8A7794)

until "[PATCH v4 00/23] soc: renesas: Add R-Car RST driver for
obtaining mode pin state" went it, which will remove that call.
