stable inclusion from stable-v6.6.2 commit 4720809ee9a3f298888c4bf2b8e6e4bfcce1bd75 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 99a8f8764b70158a712992640a6be46a8fd79d15 ]
GPLL clock rates are fixed and shouldn't be scaled based on the request from dependent clocks. Doing so will result in the unexpected behaviour. So drop the CLK_SET_RATE_PARENT flag from the GPLL clocks.
