Is that something I cribbed from another file? Ah, I see 'spear_smi.txt' which is an NAND driver with a 'clock-frequency' parameter (probably before 'assigned-clocks' support). https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/mtd/spear_smi.txt I don't think 'STMMAC' makes sense. +- interrupts: irq to be used Maybe? Same as mxc-nand.txt. It is not so helpful though. > +- nand-bus-width: see nand.txt > +- nand-ecc-mode: see nand.txt > +- nand-on-flash-bbt: see nand.txt > +- clock-frequency : Optional clock rate to NFC in Hz I guess this changed? We might want to put a note about what kind of impact this might have on the bus. Ie, assigned-clocks: Input SOC clock to the NAND controller. assigned-clock-rates: The NAND bus timing is derived from this clock rate and should not exceed maximum timing for any NAND memory chip in a board stuffing. Typical NAND memory timings derived from this clock are found in the SOC hardware reference manual. Originally, the reason I made this file was because the 'clock-frequency' was non-standard. I guess it is nice to have it anyways. Fwiw, Bill Pringlemeir. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
