soc/tegra: Add efuse driver for Tegra

2014-07-17T12:36:01+00:00

Implement fuse driver for Tegra20, Tegra30, Tegra114 and Tegra124. This replaces functionality previously provided in arch/arm/mach-tegra, which is removed in this patch. While at it, move the only user of the global tegra_revision variable over to tegra_sku_info.revision and export tegra_fuse_readl() to allow drivers to read calibration fuses.

ARM: tegra: Use a function to get the chip ID

2014-07-17T11:36:41+00:00

Instead of using a simple variable access to get at the Tegra chip ID, use a function so that we can run additional code. This can be used to determine where the chip ID is being accessed without being available. That in turn will be handy for resolving boot sequence dependencies in order to convert more code to regular initcalls rather than a sequence fixed by Tegra SoC setup code.

ARM: tegra: Sort includes alphabetically

2014-07-17T11:29:57+00:00

If these aren't sorted alphabetically, then the logical choice is to append new ones, however that creates a lot of potential for conflicts because every change will then add new includes in the same location. Signed-off-by: Thierry Reding

ARM: tegra: Move includes to include/soc/tegra

2014-07-17T11:26:47+00:00

In order to not clutter the include/linux directory with SoC specific headers, move the Tegra-specific headers out into a separate directory. Signed-off-by: Thierry Reding

ARM: tegra: add missing break to fuse initialization code

2013-12-12T01:09:11+00:00

Add a missing break to the switch in tegra_init_fuse() which determines which SoC the code is running on. This prevents the Tegra30+ fuse handling code from running on Tegra20.

ARM: tegra: switch FUSE clock on before usage

2013-12-04T19:24:22+00:00

FUSE clock is enabled by most bootloaders, but we cannot expect it to be on in all contexts (e.g. kexec). Ensure the FUSE clock is enabled before any of its registers is touched. Since FUSE is touched very early during system boot (before the clock devices are registered), directly manipulate the clock register bit in case the clock device cannot be acquired.

ARM: tegra: add fuses as device randomness

2013-10-18T22:28:06+00:00

Various fuses on Tegra include information that's unique to an individual chip, or a subset of chips. Call add_device_randomness() with this data to perturb the initial state of the random pool. Suggested-by: Linus Walleij Signed-off-by: Stephen Warren Acked-by: Linus Walleij

ARM: tegra: remove tegra_chip_uid()

2013-09-23T20:02:23+00:00

Following commit f5b38c5 "crypto: tegra - use kernel entropy instead of ad-hoc", this function is no longer used. It's also only accurate for Tegra20 and not later SoCs. So, remove it. Signed-off-by: Stephen Warren Signed-off-by: Herbert Xu
