As far as I can tell, the only difference in the init sequence between
imx290_global_init_settings_290 and imx290_global_init_settings_462 is
0x3011 register which is not present in imx290_global_init_settings_290.
It is however included in imx290_global_init_settings, and set to 0x02.
Could we therefore use imx290_global_init_settings_290 for the imx462 ?
