Hiroshi, is this driver for something (registers/features) that AMBA actually specifies? AHB might be part of AMBA (I'm not familiar enough to know), but I don't think this aspect of Tegra's AHB bus is part of any core AHB/AMBA specification, rather than being some Tegra-specific control over the bus (given that the registers and bits correspond to Tegra-specific devices on the bus). I'm not really convinced that low-level platform-specific drivers like this shouldn't be in the arch/arm/mach-* directories. _______________________________________________ devicetree-discuss mailing list devicetree-discuss@lists.ozlabs.org https://lists.ozlabs.org/listinfo/devicetree-discuss
