Alex Frid [Thu, 6 Oct 2011 04:20:21 +0000]
ARM: tegra: power: Limit CPU rate on system EDP alarm

System electrical design point (EDP) alarm is generated when system
power source (battery) over-current is detected.

Part of the system EDP management is CPU frequency capping added by
this commit. Maximum CPU clock frequency is pre-determined depending
on number of CPU cores on-line. It is combined with CPU regulator EDP
limit and applied to final CPU rate; CPU voltage is scaled down by
DVFS, respectively. The system EDP limit of CPU rate is removed after
alarm is canceled.

EDP event can be emulated via debugfs entry /d/cpu-tegra/edp_alarm.

ARM: tegra: clock: Support restricted PLLM usage

Added configuration option TEGRA_PLLM_RESTRICTED - when enabled,
PLLM - memory PLL - usage may be restricted to modules with dividers
capable of dividing maximum PLLM frequency at minimum voltage. When
disabled, PLLM is available as a clock source with no restrictions
(current configuration), which may effectively increase lower limit
for core voltage if high grade SDRAM is used.

Implemented PLLM restrictions in Tegra3 clock framework and DVFS, but
keep them disabled by default.

Alex Frid [Wed, 26 Oct 2011 06:36:26 +0000]
ARM: tegra: dvfs: Optimize Tegra3 VDD_CPU control in LP mode

Optimized Tegra3 VDD_CPU control when VDD_CPU target is set to zero,
which could happen only while CPU is in LP mode (and CPU regulator
output is turned off by side-band signal, anyway):

- Ignore VDD_CPU dependency on VDD_CORE while VDD_CPU target is zero
- Allow VDD_CPU one step change to zero (i.e., to minimum voltage set
by constraints) after entry to LP mode
- Allow VDD_CPU one step change to the predicted G mode target before
exit from LP mode

ARM: tegra: power: Enforce cpufreq policy maximum

Tegra cpu complex frequency is set by cpufreq driver to the maximum
of per-cpu target frequencies specified by the respective governors
running on each cpu core. It guarantees that final frequency is above
all per-cpu policy low limits, but policy high limit set on one core,
may be exceeded if the other core has higher target.

This commit implements complementary mode in cpufreq driver that set
final cpu frequency below all per-cpu maximum policy limits. The new
mode is disabled by default, and can be activated via

- Made sure LP3 state is reported as last entered state to cpuidle
governor in case when LP3 is entered as a fall back from LP2 path.

- Accumulate idle time designated to LP2 state by cpuidle governor
and time actually spent in LP2 by each CPU separately. Update LP2
statistic output.

ARM tegra: gpio: Correct gpio interrupt init sequence

It is possible for GPIO interrupt to occur when registering handler
since set_irq_chained_handler enables GPIO interrupt. Thus
all relevant variables are required to be initialized
before calling set_irq_chained_handler.

Also add initialization of interrupt status register.
