I guess you wanted to hear Rob's opinion ;-), but "get more performance"
sounds like we add one (or more) properties to tune those values.
If I get this right, it works with default values, but is sub-optimal?

Booted here on clearfog, and tested traffic passes between two lan
ports, and a lan port and the cpu port... and generally still seems
to work as a switch. All seems well on the face of it.

a update here, tested on 4.9,
- Applied Ard's two patches only
- Applied Robert's patch only
Both of them can work fine on D05 with NUMA enabled, which means
boot ok and LTP MM stress test is passed.
I'm not familiar with memory management, it's up to you guys to make
a decision :)

Yes, a _current_ version of the driver supports both bindings, but older
versions *require* the older binding and bail out if various
allwinner,xxx properties are missing - as in those proposed new DTs:
4.9 kernel with sunxi/for-next .dtb:
sun8i-h3-pinctrl 1c20800.pinctrl: missing allwinner,function property in
node uart0
sun8i-h3-pinctrl 1c20800.pinctrl: missing allwinner,function property in
node mmc0
sunxi-mmc: probe of 1c0f000.mmc failed with error -22

But the new compatible is not recognized with older kernels, preventing
people from using the newest DT with older kernels as well.
I proposed to simply work around this by using the old compatible as a
fallback: compatible="sun7i-a20-mmc", "sun5i-a13-mmc";
Unfortunately this suggestion was not followed.
So now we can't boot a 4.8 (or earlier) kernel with a .dtb from a 4.9 or
later tree. Adding the extra string would fix this.
Actually the recommended approach to avoid this situation in the first
place is to always use compatible strings with the SoC-specific name as
the first string, followed by the compatible string the driver works
with. And this should be done upon introducing a new DT to the tree -
even if at this point the driver doesn't deal with the new string.
Unknown strings will just be skipped.
So for instance the H5 DT should read: "sun50i-h5-mmc",
"sun50i-a64-mmc", "sun5i-a13-mmc"; (with the last string possibly being
optional). The current kernel driver will not match the h5 string, so it
falls back to the a64 string and works. If we learn about a neat eMMC
5.1 feature (or any quirk the H5 can benefit from) somewhere in the
future, we can add the code together with this h5 string to the driver
and don't need to change the DT at all.

I saw that and I appreciate that very much, but that post was not about
keeping compatibility with older DTs, but allowing older kernels to run
with the latest DT as well.
Newer DTs from your -next branch do not work with older kernels - that
is what my whole post was about. _Why_ we should care is explained there.
And please don't get me wrong: I am not asking for rewriting and bending
the whole kernel source to make this possible, it's just that we drop
this patch here, for instance, or simply not _change_ compatible names,
but instead add new strings.
Cheers,
Andre.

I split out the one-line addition to include/uapi/Kbuild with an empty

Also added a patch "media: Add userspace header file for i.MX".

yes, it needs to iterate by subdev, pads in the subdev, then links
in the pad. But I moved the code under the innermost loop into a
function imx_media_create_link(), which creates a single media
link. So it's not so much an eye-sore now.

a quick look at struct device_driver definition didn't mention that
.owner member is deprecated or not needed, so for now I'll leave
it in place. We can revisit that later.

The i.MX input capture patch will come later. These are just
placeholders until then, the config name could even change.
For now I just removed the above conditional include.

in this case I prefer not to, of_parse_subdev() is called recursively, and I
think it's bad form to hide that fact by moving the recursive call into a
separate function. The indentation is not that deep, only two loops deep.

The CSI nodes are port nodes, and the reg property is required,
so I added a check and error return here.

actually imx-media-of.h isn't really needed, I just moved those prototypes
into imx-media.h and removed imx-media-of.h.

* [PATCH v2 3/4] ARM64: dts: exynos5433: use macros for pinctrl configuration on Exynos5433
From: Andi Shyti @ 2017-01-06 2:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20170105200807.54j2ebve6kqd5bob@kozik-lap>
Hi Krzysztof,
> Andi,
> Please fix missing Signed-off-by and resend with Linus' tags for #1 and
> #2 and with other accumulated tags.
patch #1 has already been merged in mainline:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1259feddd0f83649d5c48d730c140b4f7f3fa288
and patch #2 is in LinusW's -next branch.
does it still make sense to send them again? If you want I can
send again patch 3 and 4 as independent patches with Chanwoo's
review (the only tags).
Thanks,
Andi

Hi Hans,
The dependence on [1] has been merged in 4.10, but [2] has not.Do you have
any idea about this patch series? Should we wait for [2] or we could merge
the source code and dt-binding first?

I would expect that check in the mfd code. Probe should not be
called at all if the sub-device is disabled.

* [RESEND] spi: davinci: Allow device tree devices to use DMA
From: David Lechner @ 2017-01-06 3:26 UTC (permalink / raw)
To: linux-arm-kernel
This allows SPI devices specified in a device tree to use DMA when the
master controller.
Since device tree is supposed to only describe the hardware, adding such
a configuration option to device tree would not be acceptable. So, this
is the best we can do for now to get SPI devices working with DMA.
Unfortunately, this excludes the possibility of using one SPI device with
DMA and one without on the same master.
Signed-off-by: David Lechner <david@lechnology.com>

When I originally submitted this patch, there was some discussion as to whether
dspi->dma_rx should be changed to return an error rather than being null.
However, I prefer it the way it is and don't see a compelling reason to change
it.

You have my "Tested-by" for this version as well :-). Patches works
great after applying them over v4.10-rc2.
I used crash-utility from below where there are few patches queued for
crash-7.1.8

This controls the charge current. I believe the correct property to use
is CONSTANT_CHARGE_CURRENT. And you should add CONSTANT_CHARGE_CURRENT_MAX
which returns the highest possible setting.
Also letting the user control this might not always be a good idea.
IIUC, LiPo batteries can only be charged at 1C, where C is the
rated capacity (X mAh).

You can also add POWER_SUPPLY_PROP_TECHNOLOGY, which would return
POWER_SUPPLY_TECHNOLOGY_LIPO.
It is also possible to do POWER_SUPPLY_PROP_CHARGE_TYPE. According
to the manual, if the battery is charging, it is in constant current
mode (POWER_SUPPLY_CHARGE_TYPE_FAST) when V_battery < V_target.
When V_battery == V_target, it is in constant voltage mode, though
I don't think this is the same as POWER_SUPPLY_CHARGE_TYPE_TRICKLE.
When it is not charging, you can return POWER_SUPPLY_CHARGE_TYPE_NONE.

* [PATCH v6 0/4] arm64: arch_timer: Add workaround for hisilicon-161601 erratum
From: Ding Tianhong @ 2017-01-06 3:41 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483594317-10732-1-git-send-email-dingtianhong@huawei.com>
Hi Marc, Will:
Please help reviewing the new version, I think it is nearly close to the final solution and it is very important to our chip or something else chip has similar erratum.
If there is any dissatisfaction, please inform me and I will fix it. :)
Thanks a lot.

* [PATCH 2/2] media: rc: add driver for IR remote receiver on MT7623 SoC
From: Andi Shyti @ 2017-01-06 3:43 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483632384-8107-3-git-send-email-sean.wang@mediatek.com>
Hi Sean,
> + ir->rc = rc_allocate_device();
Yes, you should use devm_rc_allocate_device(...)
Besides, standing to this patch which is not in yet:
https://lkml.org/lkml/2016/12/18/39
rc_allocate_device should provide the driver type during
allocation, so it should be:
ir->rc = rc_allocate_device(RC_DRIVER_IR_RAW);
and this line can be removed:
> + ir->rc->driver_type = RC_DRIVER_IR_RAW;
I don't know when Mauro will take the patch above.

* [PATCH v3 0/5] Add touch key driver support for TM2
From: Jaechul Lee @ 2017-01-06 3:59 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <CGME20170106035913epcas5p2b7d66596e467c6169786eea56beb8ffc@epcas5p2.samsung.com>
Hi,
This patchset adds support for the tm2 touchkey device.
The driver has been ported from Tizen Kernel, originally written
by Beomho. I ported it to the latest mainline Kernel.
This patch need to apply after this one:
https://lkml.org/lkml/2016/12/29/319
Changes in v3:
- Changed the commit ordering, the tm2-touchkey related patches
are the last 3.
- Added Chanwoo's patch which fixes the wrong voltage of ldo23
and ldo25.
- Andi (patch 3) moves the ldo31 and ldo38 in the tm2 and tm2e
files as they have different values.
Changes in v2:
- fixed reviews from Javier, Dmitry
- refactored power enable/disable functions.
- reordered signed-offs in patch 2, while patch 4 is left as it
was as Andi copy pasted the node to the new tm2.dts file
- added Jarvier's (patch 1,2,4) and Krzysztof's (patch 4) reviews
and Rob's Ack
- patch 3 diff has been generated with -B50%

* [PATCH v3 2/5] arm64: dts: exynos: make tm2 and tm2e independent from each other
From: Jaechul Lee @ 2017-01-06 3:59 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483675149-32598-1-git-send-email-jcsing.lee@samsung.com>
From: Andi Shyti <andi.shyti@samsung.com>
Currently tm2e dts includes tm2 but there are some differences
between the two boards and tm2 has some properties that tm2e
doesn't have.
That's why it's important to keep the two dts files independent
and put all the commonalities in a tm2-common.dtsi file.
At the current status the only two differences between the two
dts files (besides the board name) are ldo31 and ldo38.

* [PATCH v3 4/5] input: tm2-touchkey: Add touchkey driver support for TM2
From: Jaechul Lee @ 2017-01-06 3:59 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483675149-32598-1-git-send-email-jcsing.lee@samsung.com>
This patch adds support for the TM2 touch key and led
functionality.
The driver interfaces with userspace through an input device and
reports KEY_PHONE and KEY_BACK event types. LED brightness can be
controlled by "/sys/class/leds/tm2-touchkey/brightness".
