PATCH 1/1 ARM: enable SUSPEND/ARCH_SUSPEND_POSSIBLE for ARCH_TEGRA
From: Stephen Warren <[email protected]>
Even though system suspend/resume hasn't been validated on Tegra yet, this Kconfig option needs to be enabled so that system shutdown is reliable on an SMP system. Without it, I2C interrupts may be routed to CPU0, whereas shutdown code may be running on CPU1, causing I2C timeouts, preventing communication with the external PMIC.
This reverts 3d5e8af "ARM: disable SUSPEND/ARCH_SUSPEND_POSSIBLE for ARCH_TEGRA".

Applied to Tegra's for-3.7/fixes branch.
