With MFD devices the clk properties may be contained in MFD (parent) DT node. Current devm_of_clk_add_hw_provider assumes the clk is bound to MFD subdevice not to MFD device (parent). Add devm_of_clk_add_hw_provider_parent to tackle this issue. Also clkdev registration lacks of managed registration functions and it seems few drivers do not drop clkdev lookups at exit. Add devm_clk_hw_register_clkdev and devm_clk_release_clkdev to ease lookup releasing at exit. Signed-off-by: Matti Vaittinen <redacted>

Right. Didn't spot the #ifdef CONFIG_OF in clk-provider.h. So patch lacks of stub functions for non OF architectures. The 0-Day test system spot this. Tomorrow I'll send v2 where the inlined stub functions for non OF architectures are added. Br, Matti Vaittinen -- Matti Vaittinen ROHM Semiconductors ~~~ "I don't think so," said Rene Descartes.
