The current binding for the TCB is not flexible enough for some use cases
and prevents proper utilization of all the channels.

* [PATCH 00/45] Migrate TCB bindings
From: Alexandre Belloni @ 2017-12-19 21:31 UTC (permalink / raw)
To: linux-arm-kernel
Hi,
As the bindings were acked by Rob a while ago [1] and I think there is
consensus on what they look like, I'm planning to apply that series for
4.16 so we get a smoother transition for the TCB driver rework.
I've simply removed the PWM binding change that I will submit with the
driver change itself.
There is also a small fix in the at91sam9261ek patch.

* [PATCH v2] ARM: dts: sunxi: Add sid for a83t
From: kevans91 at ksu.edu @ 2017-12-19 21:05 UTC (permalink / raw)
To: linux-arm-kernel
Allwinner a83t has a 1 KB sid block with efuse for security rootkey and
thermal calibration data, add node to describe it.
a83t-sid is not currently supported by nvmem/sunxi-sid, but it is
supported in an external driver for FreeBSD.
Signed-off-by: Kyle Evans <kevans91@ksu.edu>

Changes in v2:
- remove bogus "From:" line in commit text; no functional change

In looking at this patch, I wonder: is there anything listed here that
is _missing_ from CONFIG_PTDUMP? I would expect all of these to
already be listed there, but I thought I'd ask...
Regardless:

* [net-next: PATCH 0/8] Armada 7k/8k PP2 ACPI support

Hi Marcin
I know ~0 about ACPI. But what seems to be missing for me is
documentation. You are defining a ABI here, which all future MDIO
busses, PHYs, and to some extent Ethernet switches need to follow. So
i would expect this to be documented somewhere.
How does documentation work in the ACPI world?

Yes, I model the modelling of models of modeled timers. Is that not

an interface to the GIC for level ...
