The J721S2 binding is based on the TI downstream binding in 54b0f2a00d92 ("arm64: dts: ti: k3-j721s2-main: add gpu node") from [1] but with updated compatible strings. The clock[2] and power[3] indices were verified from docs, but the source of the interrupt index remains elusive. References for indices: clocks[1], interrupts[2], power[3].
