It might grow to add support for other platforms from Mobileye. It handles 10 read-only PLLs derived from the main crystal on board. It exposes a table-based divider clock used for OSPI. Other platform clocks are not configurable and therefore kept as fixed-factor devicetree nodes. Two PLLs are required early on and are therefore registered at of_clk_init(). Those are pll-cpu for the GIC timer and pll-per for the UARTs.
