The mux clock is sourced by default from the DPLL_ABE_X2_CLK, and this results in a rather odd clock frequency (361 MHz) for the IPU1 functional clock on platforms where ABE_DPLL is configured properly. Reconfigure the mux clock to be sourced from CORE_IPU_ISS_BOOST_CLK (dpll_core_h22x2_ck), so that both the IPU1 and IPU2 are running from the same clock and clocked at the same nominal frequency of 425 MHz. This also ensures that IPU1 functional clock is always configured properly and becomes independent of the state of the ABE DPLL on all boards.
