[PATCH 2/3] clk: add prepare/unprepare helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



barebox doesn't use interrupts, so it need not differentiate between a
possibly sleeping prepare/unprepare and an atomic enable/disable.

Provide a wrapper that just expands to the already existing functions to
simplify porting of Linux kernel drivers.
