I stumpled upon this, when familiarizing myself with clk drivers. Unfortunately,
I have no boards to test this patch. It seems the only user of this flag in
mainline is drivers/clk/imx/clk-composite-7ulp.c, therefore I'm cc-ing
get_maintainers.pl --git-blame -f drivers/clk/imx/clk-composite-7ulp.c
in the hopes of a wider audience.

V1: https://lore.kernel.org/lkml/20230529133433.56215-1-frank@oltmanns.dev/

Changes since V1:
 - Added test case as requested by Stephen Boyd
 - Fixed commit message as the Cc: was missing a closing bracket, so that the
   original mail unfortunately did not go out to A. s. Dong.

Thank you for considering this contribution,
  Frank
