| |
Hello,
Lets say there is a clock which is enabled by bootloaders and is pre running as linux boots. Is it mandatory for the client drivers to call clk_prepare_enable() on them to initialise the enable_count to 1?
Or is there a way we can specify to the kernel that this clock is already enabled by bootloader and initialise the enable_count for this clock to 1.
Because otherwise, clk_disable() prints a WARN() if a client driver uses clock handle where clk_prepare_enable() is not called.
I grep through the code, but could find any details. Appreciate any pointers.
Regards, Arun
