As I developed the bcm281xx clock code I understood there were
restrictions on device tree "compatible" strings names, and as a
result "bcm11351" was used in places despite the part family being
more properly called "bcm281xx". This can be a little confusing.
In some cases I went to far and

Hi,
another iteration of this series. The patches are the same as in v3, but
the series shrank a bit. I rebased this series on tip/timers/core, hence
the two patches for the clockevent core fell out, since Thomas already
applied those.
Additionally I removed the patch 'clocksource/cadence_ttc:

The code I'm familiar with is ntpd and gpsd. They run on almost any hardware
The currently used method adjusting the clocksource to a changing input
frequency does not work on kernels from 3.11 on.
The new approach is to keep the timer frequency as constant as possible.
I.e.
- due to the TTC's prescaler limitations, allow frequency changes
only if the frequency scales
The timer frequency of the arm_global_timer depends on the CPU
frequency. With cpufreq altering that frequency the arm_global_timer
does not maintain a stable time base. Therefore don't enable that timer
in case cpufreq is enabled.

The generic cpufreq-cpu0 driver can scale the CPU frequency on Zynq

Since deadline tasks share rt bandwidth, we must care about
bandwidth timer set. Otherwise rt_time may grow up to infinity
in update_curr_dl(), if there are no other available RT tasks
on top level bandwidth.
I'm going to decide the problem the way below. Almost untested
because of I skipped
The address translation of a PCI node don't require anymore the PCI
support in the kernel. This translation is mandatory to be able to
read the SoC ID which is stored in the PCI controller of the mvebu
SoCs.
This patch selects the symbol needed to get only this translation for
all the mvebu
Translating an address from a PCI node of the device-tree into a CPU
physical address doesn't require the core PCI support. Those
translations are just related to the device tree itself.
The use case to translate an address from a PCI node without actually
using the PCI core support is when one
Hello,
This patch set makes the use of the of PCI address translator less
restrictive. At the end it will allow to use the mvebu_get_soc_id
unconditionally.
The mvebu SoC (such as Kirkwood, Dove or Armada XP for instance) come
with an IP of a PCI controller. The ID and the revision of a SoC are
Kmemcheck should use the preferred interface for parsing command line
arguments, kstrto*(), rather than sscanf() itself. Use it appropriately.
