usb: xhci: tegra: remove PCIe dependency

PCIe powergating dependency is now handled internally in the powergating module
for t12x/t13x. This patch removes PCIe related powergating calls from XHCI
driver for tegra.

Haribabu Narayanan [Tue, 17 Jun 2014 00:57:46 +0000]
arm: tegra: power: add pcie dependency to xusb ops

Due to a HW bug 1320346 in t12x/t13x, PCIE needs to be unpowergated when XUSB
is to be accessed.  Currently PCIE powergating ops need to be invoked from XUSB
driver since powergating module doesn't internally handle this dependency.

This patch implements this dependency within the powergating module so that
xhci-tegra driver can stay chip-agnostic.

4 years agocpufreq: ondemand: Change the calculation of target frequency
Stratos Karafotis [Wed, 5 Jun 2013 16:01:25 +0000]
cpufreq: ondemand: Change the calculation of target frequency

The ondemand governor calculates load in terms of frequency and
increases it only if load_freq is greater than up_threshold
multiplied by the current or average frequency.  This appears to
produce oscillations of frequency between min and max because,
for example, a relatively small load can easily saturate minimum
frequency and lead the CPU to the max.  Then, it will decrease
back to the min due to small load_freq.

Change the calculation method of load and target frequency on the
basis of the following two observations:

 - Load computation should not depend on the current or average
   measured frequency.  For example, absolute load of 80% at 100MHz
   is not necessarily equivalent to 8% at 1000MHz in the next
   sampling interval.

 - It should be possible to increase the target frequency to any
   value present in the frequency table proportional to the absolute
   load, rather than to the max only, so that:

   Target frequency = C * load

   where we take C = policy->cpuinfo.max_freq / 100.

Tested on Intel i7-3770 CPU @ 3.40GHz and on Quad core 1500MHz Krait.
Phoronix benchmark of Linux Kernel Compilation 3.1 test shows an
increase ~1.5% in performance. cpufreq_stats (time_in_state) shows
that middle frequencies are used more, with this patch.  Highest
and lowest frequencies were used less by ~9%.

[rjw: We have run multiple other tests on kernels with this
 change applied and in the vast majority of cases it turns out
 that the resulting performance improvement also leads to reduced
 consumption of energy.  The change is additionally justified by
 the overall simplification of the code in question.]

media: platform: tegra: support 64 bit user code

Since the user space code may works in either 32 or 64 bit mode,
attentions should be taken while passing pointers from user space to
the kernel. In this case, the p_value of struct nvc_param and
power_on/power_off of struct virtual_device received from the user
space should be handled properly.

The solution is to create a set of 32 bit version of structures
nvc_param and virtual_device along with some dedicated 32 bit mode
ioctl commands, then in the ioctl functions, the 32 bit user mode
access will be handled separately.

5 years agousb: gadget: tegra: handle the case when host reboots

usb: gadget: tegra: handle the case when host reboots

Some hosts during booting first supply vbus and then
send setup packets after x seconds. In this case we detect
as non-standard. Handle this case by setting to SDP.

Also adding condition to avoid unnecessary icon
notifications.

5 years agousb: phy: tegra: QC2 speed up charger recogniion

usb: phy: tegra: QC2 speed up charger recogniion

The QC2 Wall Charger needs to be reset only when
we boot or reboot the system.  This is because
the wall charger will have already defaulted to a DCP.
Since the internal logic in the Wall Charger will not
see D+/D- programmed during the time available.

If we just plug in the charger then it will be recognised
in time so no reset is necessary.  Removes 1.5s of delay.

devfreq: Account only powered time in trans_stat

This patch modifies devfreq to account only the time a device is
powered in trans_stat. In addition, this patch also fixes a race
in trans_stat maintenance in cases where the node is readed at
the same time the transition table is being updated by frequency
re-estimation.

Previously, sysedp was attempted to enabled on non-battery versions of
P1761. This caused sysedp_batmon_calc to fail with -EFAULT during
probing as battery power supply was not available.
