Here as well you ignored my first comment:
https://lore.kernel.org/lkml/CANAwSgS=08fVsqn95WHzSF71WTTyD2-=K2C6-BEz0tY0t6A1-g@mail.gmail.com/T/#mbfc57b40a7ed043dd4d4890bedb6bad8240058cd

"This is not valid reason to do a change. What is clk_summary does not
really matter. Your change has negative impact on power consumption as
the clock stays enabled all the time. This is not what we want... so
please explain it more - why you need the clock to be enabled all the
time? What is broken (clk_summary is not broken in this case)?"

This was not addressed, you just resent same code...


Best regards,
Krzysztof
