The device_is_bound() is unvisable to drivers when built as modules. It's also not aimed to be used by drivers according to Greg K.H. Let's remove it from clk-scu driver and find another way to do proper driver loading sequence.Greg was asking to use device_link for this issue. Have you tried something like the following: (untested as I dont have the hardware).It can't work as expected because it requires supplier devices (scu pd) to be probed first. and if scu pd was probed first, then there're already no issues.
hmm.. thats odd. I was expecting that if "scu-pd" has not registered then device_link_add() will return NULL and then imx_clk_scu_init() will return -EPROBE_DEFER. -- Regards Sudip _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
