But, as the DAX people found out, ioremap in a file system drivers is a big no-no when you are trying to get a new file system into mainline. Nicolas (Pitre) also ran into this when he was adding XIP support to cramfs last year....hence mtd-rom is mandatory for that. I would like us to be able to flag a clock as critical without a specific use case to look for (ie, looking for mtd-rom). For RZ/A1, we're all set because we can do it in the board's .dst. Easy! I just wish it was that easy for RZ/A2 (using the newer renesas-cpg-mssr driver). Chris
