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. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
