From: Thierry Reding <treding@xxxxxxxxxx> This series is an extension of Peter's original series to add a proper driver for the FUSE block on Tegra. Patches 1 and 2 are preparatory work that cleans up include lists and introduces a function to query the Tegra chip ID rather than accessing a simple variable. This is used by subsequent patches to allow us to execute code when the variable is accessed to help in pin-pointing locations where it's accessed before the driver had a chance to initialize. Patches 3 through 8 are Peter's series with a fixup patch by Stephen. I also moved the driver to drivers/soc/tegra/fuse as requested by Olof. Patches 9 and 10 defer usages of the tegra_get_chip_id() function to a later stage (pure_initcall). This allows patch 11 to set up the early FUSE support code from an early initcall. This has the advantage of not requiring an explicit call from SoC setup code in arch/arm/mach-tegra and will allow the code to be shared on 64-bit variants of Tegra. Patch 12 finally turns the PMC and powergate support code into a proper driver which also sets up a minimal environment from an early initcall. The driver isn't moved out of arch/arm/mach-tegra yet because people have suggested drivers/power as a good home, but that whole directory depends on the POWER_SUPPLY Kconfig symbol yet this driver doesn't have anything to do with that. Once that debate has been settled the driver can easily be moved out in a separate patch. Some of the patches in this series introduce diagnostic WARN() messages if functions are called without setup having completed. I've booted the v3.16-rc1 kernel with these changes on top on Tegra20 (TrimSlice), Tegra30 (Beaver), Tegra114 (Dalmore) and Tegra124 (Jetson TK1) without encountering any of the diagnostic warnings and without noticing any breakage. Olof, this series should address the concerns you expressed after reviewing Stephen's earlier pull request for Peter's FUSE driver series. It would be great if you could take another look to see if this is more according to your taste. I'll see if I can take this through linux-next for a little and if you have no objections will submit another pull request next week.
