I wrote a long explanation of the issue, but the summary is: The timer (which is currently using TIMER_OF_DECLARE) can't start up until the clocks are set up because of_clk_get fails(). But, the clock driver is a platform driver that is not started until subsys_initcall. So, unless you have a clock driver with CLK_OF_DECLARE, you can't use a timer driver with a TIMER_OF_DECLARE driver. And, there is no such thing as a deferred probe for timer drivers declared with IMER_OF_DECLARE. Chris
