Video PLL factors can be set in a way that final PLL rate is outside

be below 12. While it doesn't says anything about maximum stable rate, it
Manual says "In application, PLL_FACTOR_N should be more than or equal
to 11" can't it be 11?
is clear that PLL doesn't work at 6.096 GHz (254 * 24 MHz).
Set minimum allowed PLL video rate to 288 MHz (12 * 24 MHz) and maximum
to 2.4 GHz, which is maximum in BSP driver.
Is this max freq from here [1]
