It is a different block from the IEP of RK3228/RK3288/RK3328/RK3399, hence "iep2". The RK3588 block falls back to the RK3568 compatible: the vendor kernel drives both with one compatible ("rockchip,iep-v2") and one driver. Clock and reset names follow the RGA binding. The resets are optional: the block has its own soft reset.
