It's unfortunate that whether ICE is present needs to be explicitly declared for each SoC here (I would have expected that to only be done in the device tree files themselves), and that the order of the regs and clocks is fixed (I would have expected them to act as maps keyed by name). But it seems that's the way it is. Reviewed-by: Eric Biggers <ebiggers@google.com> - Eric
