ARM: tegra: Add dvfs rails

The previous version of dvfs handled requirements between two
different voltage rails by using two sets of dvfs tables, one
for each rail.  That method fails for vdd_aon, which must be
within 170 mV of vdd_core.

Instead, have each dvfs clock only set the voltage rail that
it directly depends on, and add a relationship system to the
voltage rails.  When the voltage changes on one rail, it calls
update on all the rails that depend on it.  The dependent rails
compare the new voltage of the original rail to their own
voltage, and update their own voltage as necessary.

Mike Chan [Tue, 22 Jun 2010 18:26:45 +0000 (11:26 -0700)]
cpufreq: interactive: New 'interactive' governor

This governor is designed for latency-sensitive workloads, such as
interactive user interfaces.  The interactive governor aims to be
significantly more responsive to ramp CPU quickly up when CPU-intensive
activity begins.

Existing governors sample CPU load at a particular rate, typically
every X ms.  This can lead to under-powering UI threads for the period of
time during which the user begins interacting with a previously-idle system
until the next sample period happens.

The 'interactive' governor uses a different approach. Instead of sampling
the CPU at a specified rate, the governor will check whether to scale the
CPU frequency up soon after coming out of idle.  When the CPU comes out of
idle, a timer is configured to fire within 1-2 ticks.  If the CPU is very
busy from exiting idle to when the timer fires then we assume the CPU is
underpowered and ramp to MAX speed.

If the CPU was not sufficiently busy to immediately ramp to MAX speed, then
the governor evaluates the CPU load since the last speed adjustment,
choosing the highest value between that longer-term load or the short-term
load since idle exit to determine the CPU speed to ramp to.

A realtime thread is used for scaling up, giving the remaining tasks the
CPU performance benefit, unlike existing governors which are more likely to
schedule rampup work to occur after your performance starved tasks have
completed.

The tuneables for this governor are:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_time:
The minimum amount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic CPU load data to determine the appropriate workload.
Default is 80000 uS.
/sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
The CPU load at which to ramp to max speed.  Default is 85.

mfd: cpcap-3mm5: Fix for missing key event on resume

The key_handler was checking the sense bits to see whether a press
or release occurred.  The problem with this is it takes so long to
resume from LP0/LP1, that the key state could have changed again
before the handler has even ran.  The driver would see the key was
currently released, which was the same state it last reported, and
not send a new event.

This patch changes the handler so it does not check the sense bits.
It simply sends a press when the MB2 interrupt occurs and a release
when the MACRO_5 interrupt occurs.

This fixes the kernel portion of bug 3225781.

13 years ago[ARM] tegra: dma: Single buffered continuous DMA
Chris Fries [Thu, 11 Nov 2010 23:39:06 +0000 (17:39 -0600)]
[ARM] tegra: dma: Single buffered continuous DMA

- Added "single buffer continuous DMA" mode in addition to the
  "double buffer continuous DMA" mode that is already implemented
- Changed the queuing of next buffer to be more flexible for
  continuous DMA.  It can now get in-flight right after a transfer
  starts, or whenever the client enqueues a buffer.
