Could you elaborate it? Arasan is an IP vendor, and those IPs are usually embedded in specific SoCs. I guess Rob was suggesting to define something like: compatible = "<soc-vendor>,<ip-revision>", "arasan,<ip-revision>"; This way you can differentiate minor changes/tweaks between each SoC (each SoC vendor usually enable/disable specific features based on their needs). > > > > +- reg: Memory map for module access > > > +- interrupt-parent: Interrupt controller the interrupt is routed through > > > +- interrupts: Should contain the interrupt for the device > > > +- clock-name: List of input clocks - "clk_sys", "clk_flash" > > > > clk_ is redundant. > > > > I have defined these clock names as per the controller data sheet. > So, I feel it is fine to have them in sync with the datasheet. > Please let me know if you still want me to change this. We already know this is a clock, hence the unneeded clk_ prefix. Please drop it.
