Adding board specific suspend and resume call apis through platform data. Added call of these function at appropriate stage of suspend/resume. Added mechanism to select the uart debug channel base address through variable so that board file can directly change this. bug 820536 bug 832273 Original-Change-Id: Ia9ff3b8a8d2faa1071a8ff634960e6a6c8a43d40 Reviewed-on: http://git-master/r/34494 Reviewed-by: Varun Colbert <vcolbert@nvidia.com> Tested-by: Varun Colbert <vcolbert@nvidia.com> Rebase-Id: R6d7bfb3f8f9152779f5138cbcd1b7a9e9a9545df

2011-11-30ARM: tegra2: power: Fix reset race condition between the CPUsScott Williams
During LP2 for CPU idle on Tegra2, there could be a race condition between the CPUs. CPU1 cannot autonomously shut itself down (put itself into reset). CPU1 must be reset by CPU0 but only when it has no outstanding memory or I/O transactions going on (i.e., it is in the WFI state). CPU1 indicates its readiness to be reset by setting status in a PMC scratch register. If CPU1 wakes up and CPU0 sees CPU1's ready to be reset status before CPU1 can clear it CPU1 could be reset at inappropriate times resulting in loss of cache coherency and ultimately a kernel panic. Eliminate the race condition by ensuring that: - CPU1's reset ready status is cleared as early as possible before CPU1 rejoins the coherent world. - Use writel when updating the IRAM LP2 status flags to ensure the IRAM and coherent memory views of the flags are consistent. - If there is not enough time remaining for CPU1 to be in LP2 for the minimum residency time, clear CPU1's reset status flag before entering WFI so that CPU0 will not wait for CPU1 to be ready to reset (since it won't be if there is insufficient time).

2011-11-30ARM: tegra: power: Save CPU context to non-cacheable stackScott Williams
The standard cpu_suspend does not work if there is an exernal L2 cache in the system individual CPUs are suspending without shutting down the whole CPU complex. As a workaround for this problem, we must save the CPU context to a non-cacheable region of memory.

2011-11-30ARM: tegra: power: Fix Tegra2 LP2 modeScott Williams
All CPUs are not created equal. CPU0 must be the one to perform the CPU complex suspend actions. CPU complex power gating and rail gating cannot be triggered from CPU1. The Linux 2.6.39 port for Tegra2 violates this hardware restriction. While it may have appeared that the system was entering LP2 state, when entered on CPU1, essentially all that happened was a WFI with no CPU complex power gating and no CPU rail gating.

Errors and invalid assumptions about how the flow controller should be programmed were introduced in the port to Linux 2.6.39. - Do not touch the flow controller HALT_EVENTS register for any of the secondary CPUs in suspend_cpu_complex(). Doing so can cause the flow controller state machine to prematurely abort resulting in fatal errors when power gating the CPU complex. - Do not touch the flow controller CSR register for any of the secondary CPUs in restore_cpu_complex(). Doing so can cause the flow controller state machine to prematurely abort resulting in the secondary CPUs waking up before they're supposed to. - suspend_cpu_complex() and restore_cpu_complex() can only be invoked from CPU 0. The hardware does not allow the CPU complex to be suspended from any other CPU.

2011-11-30ARM: tegra: power: Restore LP2 in idle protectionsScott Williams
Restore the code that was dropped in the port to Linux 2.6.39 that protects against using LP2 mode for idle when the platform suspend mode has disallowed the use of LP2 mode. Also cleans up some warning messages.

2011-11-30ARM: tegra: power: Use CONFIG_PM_SLEEP instead of CONFIG_PMScott Williams
For Linux 2.6.39, CONFIG_PM_SLEEP is the proper kernel configuration parameter to use on Tegra for power management, and not CONFIG_PM. CONFIG_PM does not have the required dependency on CONFIG_SUSPEND necessary to pull in the CPU suspend/resume functionality used by Tegra. Also fixes compilation errors when CONFIG_PM and by implication CONFIG_PM_SLEEP are not configured.
