The i.MX6 Q/DL has an erratum (ERR006687) that prevents the FEC from waking the CPUs when they are in wait(unclocked) state. As the hardware workaround isn't applicable to all boards, disable the deeper idle state when the workaround isn't present and the FEC is in use. This allows to safely run a kernel with CPUidle enabled on all i.MX6 boards. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Acked-by: David S.
