|
|
The introduction of support for CLK_SET_RATE_PARENT flag for clkctrl
|
|
clocks used a generic clock flag, which causes a conflict with the
|
|
rest of the clkctrl flags, namely the NO_IDLEST flag. This can cause
|
|
boot failures on certain platforms where this flag is introduced, by
|
|
omitting the wait for the clockctrl module to be fully enabled before
|
|
proceeding with rest of the code.
|
|
|
|
Fix this by moving all the clkctrl specific flags to their own bit-range.
|
