The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get(). This should prevent locking the modules in memory.

I don't have pending patches for the omap3isp that would conflict with this patch, so that would be fine with me.I plan to add support for DT to omap3isp + ADP1653 shortly. I have not yet started to work on this, but expect to send some first RFC patches in November.
That's very nice to hear ! And thanks for the heads up, I would have started working on it shortly. -- Regards, Laurent Pinchart -------------- next part -------------- A non-text attachment was scrubbed...
