The only purpose of this driver is to serve as a consumer of the input clock, to prevent it from being disabled by clk_disable_unused().We have a clock API to do the same (something like marking it used or so) why do you need a driver?Example: https://elixir.bootlin.com/linux/latest/source/drivers/platform/x86/pmc_atom.c#L365 If it's a DT based platform I think you can make it somehow work thru DT.
Okay, briefly looking at the state of affairs [1] seems like you need to hack it into clock provider. [1]: https://elixir.bootlin.com/linux/latest/C/ident/CLK_IS_CRITICAL -- With Best Regards, Andy Shevchenko
