* ARM: tegra: pinmux naming consistency fixesStephen Warren2014-04-171-60/+62
| | | | | | | | | | | | | | | Clean up the naming of pinmux-related objects: * Refer to drive groups rather than pad groups to match the Linux kernel. * Ensure all pinmux API types are prefixed with pmux_, values (defines) are prefixed with PMUX_, and functions prefixed with pinmux_. * Modify a few type names to make their content clearer. * Minimal changes to SoC-specific .h/.c files are made so the code still compiles. A separate per-SoC change will be made immediately following, in order to keep individual patch size down.

* ARM: tegra: reduce public pinmux APIStephen Warren2014-04-171-2/+2
| | | | | | | | | | | Remove a few unused functions from the pinmux header. They aren't currently used, and removing them prevents any new usage from appearing. This will ease moving to just pinmux_config_table() and padgrp_config_table() in the future.

* ARM: tegra: pinctrl: remove duplicationStephen Warren2014-04-171-0/+507
Much of arch/arm/cpu/tegra*-common/pinmux.c is identical. Remove the duplication by creating pinmux-common.c for all the identical code. This leaves: * arch/arm/include/asm/arch-tegra*/pinmux.h defining only the names of the various pins/pin groups, drive groups, and mux functions. * arch/arm/cpu/tegra*-common/pinmux.c containing only the lookup table stating which pin groups support which mux functions. The code in pinmux-common.c is semantically identical to that in the various original pinmux.c, but had some consistency and cleanup fixes applied during migration. I removed the definition of struct pmux_tri_ctlr, since this is different between SoCs (especially Tegra20 vs all others), and it's much simpler to deal with this via the new REG/MUX_REG/... defines. spl.c, warmboot.c, and warmboot_avp.c needed updates due to this, since they previously hijacked this struct to encode the location of some non-pinmux registers. Now, that code simply calculates these register addresses directly using simple and obvious math. I like this method better irrespective of the pinmux code cleanup anyway.
