Peter should probably comment on this, since I think he's touched the powergate driver the most recently. One idea might be to have the powergate IDs be "virtual", with a virtual->HW ID mapping table per SoC. The virtual IDs need not have any gaps. I'm not sure that having gaps is really much of a problem though, except for the debugfs code in powergate.c... > diff --git a/include/linux/tegra-powergate.h b/include/linux/tegra-powergate.h > +#define TEGRA_POWERGATE_DISA 18 > +#define TEGRA_POWERGATE_DISB 19 s/DIS/DSI/ perhaps? > -#define TEGRA_POWERGATE_CPU0 TEGRA_POWERGATE_CPU I expect that was added deliberately. Perhaps Peter or Joseph can comment? Admittedly, it's not used right now. BTW, while you're fiddling with powergate.c, I note that mach-tegra/pmc.c #defines some TEGRA_POWERGATE_xxx rather than including tegra-powergate.h.
