* [PATCH] ARM: at91/DT: remove atmel, use-dma-* from 9x5 and 9n12 USART nodes
From: Nicolas Ferre @ 2013-01-30 14:55 UTC (permalink / raw)
To: linux-arm-kernel
Fix the use of USART on both at91sam9x5 and at91sam9n12. In DTS, the
atmel,use-dma-[rx|tx] property is present but a DMA channel cannot be used.
Indeed the connexion between the DMA engine and the slave is not implemented
yet in Device Tree.
Note however that this property is also used for PDC (private DMA) on older
SoCs. This is why the driver alone cannot determine the validity of this
property.

* [RFC PATCH v3 0/2] ARM: update cpuinfo to print SoC model name
From: Ruslan Bilovol @ 2013-01-30 15:01 UTC (permalink / raw)
To: linux-arm-kernel
The following patches update cpuinfo to print SoC
model name for ARM.
The first patch exactly makes needed changes for ARM
architecture and adds a common approach to show SoC name.
Second patch uses this approach for TI OMAP4 SoCs (as live
example).
Why we need it?
First - the /proc/cpuinfo becomes more informative.
Added new line "SoC name" in the "cpuinfo" output for system
on a chip name. It is placed between CPU information and machine
information, so the file structure looks gracefully
('CPU-SoC-Hardware' instead of 'CPU-Hardware' that we have now)
Second - this information may be used by userspace
for different purposes (as example - OMAP4460 and
OMAP4470 SoCs have different graphics accelerators,
and userspace may want to know what libraries
to use and what module to insert if the graphics
drivers are built as modules)
Looks like there were few attempts to do similar
changes to cpuinfo without any luck (had stuck
on review) so this functionality is still not
in the kernel yet.
In this patch series the update to cpuinfo is very
short (10 lines) and easy.
Comments are welcome as usual
--------------------------------------------------
v3:
Addressed comments from Nishanth (changed 'SoC name'
field for OMAP - now it shows only SoC name without
additional info)
Updated commit messages. Updated this cover letter
with additional information
--------------------------------------------------
v2:
Addressed comments from Russel (changed 'CPU name' > 'SoC name')
Updatet commit messages. Updated cover letter

* [RFC PATCH v3 1/2] ARM: kernel: update cpuinfo to print SoC model name
From: Ruslan Bilovol @ 2013-01-30 15:01 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359558091-29251-1-git-send-email-ruslan.bilovol@ti.com>
Currently, reading /proc/cpuinfo provides userspace with CPU ID of
the CPU carrying out the read from the file.
Userspace using this information may decide what module
to load or how to configure some specific (and processor-depended)
settings or so.
However, since really different SoCs can share same ARM core,
this information currently is not so useful.
For example, TI OMAP4460 and OMAP4470 SoCs show the same
information in the /proc/cpuinfo whereas they are different.
Since in most cases ARM CPU is a part of some system on a chip (SoC),
the "cpuinfo" file looks like exactly that place, where this
information have to be displayed.
So added new line "SoC name" in the "cpuinfo" output for system
on a chip name. It is placed between CPU information and machine
information, so the file structure looks gracefully (CPU-SoC-Hardware)
Example:
/ # cat proc/cpuinfo

The same can be said of all the various other functions which the PCI
stuff expects the arch to provide, yet we seem to cope just fine...

Thanks a lot for the branch. I saw a lot of differences between
your driver and the mainline. I should spend some time If I had

When NAPI is disabled I saw a severe packet loss
(around 40% in a flood ping) which spitted out this,
[ 470.390928] net eth0: missed rxf 2000000 1c000000 0

[ 470.450315] net eth0: missed rxf 2000000 1c000000 0
When NAPI is enabled, it was working good. Though it
resulted in the same error, it recovered by itself,
which is perfectly fine for me. :)

* Commit 384a290283fde63ba8dc671fca5420111cdac19a seems to break 11MPCore boot
From: Punit Agrawal @ 2013-01-30 15:23 UTC (permalink / raw)
To: linux-arm-kernel
Hi Nicolas,
I was trying to boot 3.8-rc5 on Realview EB 11MPCore using realview-smp_defconfig as a starting point but the kernel failed to progress past the log below (config attached).
Pawel suggested I try reverting 384a290283fde63ba8dc671fca5420111cdac19a - "ARM: gic: use a private mapping for CPU target interfaces" that you've authored. With this commit reverted the kernel boots.
I am not quite sure why the commit breaks 11MPCore but Pawel (cc'd) might be able to shed light on that.
I'd be happy to test a fix as I have the board on my desk for a bit.
Thanks,
Punit

* [PATCH] Add USB of helpers and use them in the chipidea driver
From: Sascha Hauer @ 2013-01-30 15:29 UTC (permalink / raw)
To: linux-arm-kernel
This is the 2nd version of the USB of helper patch, this time with
adding support for the chipidea driver for the new properties.
Kishon, I decided against adding an extra Kconfig option for the
OF helpers since I found out the USB stuff already has enough options ;)
The helpers are now in usb-common.c which seems an appropriate place
for them. For the phy_type helpers I had a look again and saw that
it is not really phy specific, the PORTSC registers in the chipidea
driver have to be configured even without phy support compiled in.

* [PATCH 1/6] USB: move bulk of otg/otg.c to phy/phy.c
From: Sascha Hauer @ 2013-01-30 15:29 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359559782-14552-1-git-send-email-s.hauer@pengutronix.de>
Most of otg/otg.c is not otg specific, but phy specific, so move it
to the phy directory.

* [PATCH 2/6] usb: add devicetree helpers for determining dr_mode and phy_type
From: Sascha Hauer @ 2013-01-30 15:29 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359559782-14552-1-git-send-email-s.hauer@pengutronix.de>
From: Michael Grzeschik <m.grzeschik@pengutronix.de>
This adds two little devicetree helper functions for determining the
dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from
the devicetree.

* [PATCH 4/6] usb: chipidea: add PTW and PTS handling

From: Michael Grzeschik <m.grzeschik@pengutronix.de>
This patch makes it possible to configure the PTW and PTS bits inside
the portsc register for host and device mode before the driver starts
and the phy can be addressed as hardware implementation is designed.

* [PATCH 5/6] USB chipidea: introduce dual role mode pdata flags
From: Sascha Hauer @ 2013-01-30 15:29 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1359559782-14552-1-git-send-email-s.hauer@pengutronix.de>
Even if a chipidea core is otg capable the board may not. This allows
to explicitly set the core to host/peripheral mode. Without these
flags the driver falls back to the old behaviour.

Didn't you say just yesterday that you would prefer a numerical value
rather than a hook that could do random things? :-)

Hrh, right. :)
And it also helps if I modify the right struct too! Try this instead.
Overwrite sys->win_align_mem / sys->win_align_io in the setup function
as required.

I'll take it through my MFD tree.

Hmmm, there is a include/linux/mfd/ directory for kernel MFD drivers, FYI.

Great, thanks!

Sure, it's just that this header "serves" whole platform, not only the
mfd drivers (eg. there are power-related declarations there as well). If
one day it gets divided, I'll make sure that the MFD portions will find
its way into ../mfd/.

No, they're also handled by the patch. There's no -UIS versions of iciall
and bpiall prior to v7, so the operations are broadcast via IPI, hence the
use of bpiall in the else case below.

Hmm. Still not happy. Wasn't there some SoC infrastructure added to the
kernel to export this kind of information via sysfs? See:
