stable inclusion from stable-v6.6.13 commit 351bcf3a3772fceebd12c700b534c4f8d2523041 bugzilla: https://gitee.com/openeuler/kernel/issues/I99TJK
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 1af27671f62ce919f1fb76082ed81f71cb090989 ]
Add support for a PLL rate of 292.5MHz so that the Powkiddy RGB30 panel can run at a requested 60hz (59.96, close enough).
I have confirmed this rate fits with all the constraints listed in the TRM for the VPLL (as an integer PLL) in Part 1 "Chapter 2 Clock & Reset Unit (CRU)."
