Stephen Warren 9eb4b91e69 arm/tegra: Harmony: Configure PMC for low-level interrupts
Without this, the PMC continually detects an interrupt when the PMU_IRQ
line is high, causing the tps6686x IRQ handler thread to hog an entire
CPU.

This change was originally written by Wei Ni <wni@nvidia.com> for Seaboard
in the ChromeOS kernel.

Long-term, this should probably be moved into some kind of PMU driver,
or perhaps integrated into the GPIO/IRQ/pinmux system?

Stephen Warren f2a4d8ae4d ARM: Tegra: Harmony: Fix conflicting GPIO numbering
Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.

To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.

This fixes a regression introduced by commit
6f168f2fa6.

Mike Rapoport 6f168f2fa6 ARM: tegra: harmony: initialize the TPS65862 PMIC
Initialize the PMIC voltage regulators and provide the supply map for
PCI-e clock supply. The rest of the supplies should be added together
with the drivers that use them.
