* [PATCH v6 0/2] Add ACPI support and SMBus block read
From: Austin Christ @ 2016-10-11 16:27 UTC (permalink / raw)
  To: linux-arm-kernel

From: Austin Christ <austinwc@qti.qualcomm.com>

Add ACPI support to I2C QUP driver and get properties from ACPI table.

Add support to the I2C QUP driver to correctly handle SMBus block reads by
checking I2C_M_RECV_LEN flag and reading the first byte received as the
message length.

Documentation for the two properites used from ACPI has been submitted through
dsd at acpica.org to https://github.com/ahs3/dsd. The documentation can be viewed
at https://lists.acpica.org/pipermail/dsd/2016-September/000095.html.

[V6]
 - correct block size for SMBus data read
[V5]
 - remove warning and use correct ACPI function
[V4]
 - correct error code
 - remove warning for fall back to default clock frequency
[V3]
 - clean up unused variables
 - use constant instead of variable for smbus length field
[V2]
 - rework the smbus block read and break into separate function
 - clean up redundant checks and variables

This patch is no longer needed;
the following patch is handle the issue:
http://www.spinics.net/lists/arm-kernel/msg535313.html

The PWM clock will match the parent clock (i.e. update at
initialization) if the PWM divider value was setup to 0
(i.e. gating functionality).

* [PATCH v2 8/9] ARM: sunxi: Remove useless allwinner,pull property
From: Maxime Ripard @ 2016-10-11 15:46 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.7edc6c25be8a5e2efdda6a82e102dbf7ece6aa64.1476200742.git-series.maxime.ripard@free-electrons.com>

The allwinner,pull property set to NO_PULL was really considered our
default (and wasn't even changing the default value in the code).

Remove these properties to make it obvious that we do not set anything in
such a case.

* [PATCH v2 6/9] dt-bindings: pinctrl: Deprecate sunxi pinctrl bindings
From: Maxime Ripard @ 2016-10-11 15:46 UTC (permalink / raw)

The generic pin configuration and multiplexing should be preferred now,
even though we still support the old one.

* [PATCH v2 5/9] pinctrl: sunxi: Support generic binding
From: Maxime Ripard @ 2016-10-11 15:46 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.7edc6c25be8a5e2efdda6a82e102dbf7ece6aa64.1476200742.git-series.maxime.ripard@free-electrons.com>

Our bindings are mostly irrelevant now that we have generic pinctrl
bindings that cover exactly the same uses cases.

Add support for the new ones, and obviously keep our old binding support in
order to keep the ABI stable.

* [PATCH v2 4/9] pinctrl: sunxi: Deal with configless pins
From: Maxime Ripard @ 2016-10-11 15:46 UTC (permalink / raw)
  To: linux-arm-kernel

Even though the our binding had the assumption that the allwinner,pull and
allwinner,drive properties were optional, the code never took that into
account.

Fix that.

So far, putting NO_PULL in allwinner,pull was ignored, behaving like if
that property was not there at all.

Obviously, this is not the right thing to do, and in that case, we really
need to just disable the bias.

In addition to the fact, as mentioned by Will, that contiguous PMDs
are supported for 4k and 64k granules too, this series fails to deal
with folded PUDs and PMDs (which should result in contiguous PGDs for
2 level or 3 level configurations)

Since this is no longer a drive-by patch, I wil take some time for the
v3 and address all the corner cases, and do some more elaborate
testing.

Since we have some bindings header for our hardcoded flags, let's use them
when we can.

* [PATCH v2 1/9] pinctrl: sunxi: Rework the pin config building code

In order to support more easily the generic pinctrl properties, rework the
pinctrl maps configuration and split it into several sub-functions.

One of the side-effects from that rework is that we only parse the pin
configuration once, since it's going to be common to every pin, instead of
having to parsing once for each pin.

* [PATCH v2 0/9] pinctrl: sunxi: Generic bindings rework
From: Maxime Ripard @ 2016-10-11 15:45 UTC (permalink / raw)
  To: linux-arm-kernel

Hi,

This patch set reworks the Allwinner pinctrl driver to support the generic
pin configuration and multiplexing bindings.

In the process, we also covered some lasting issues that were found: we
were ignoring the case where no pull-up was set, and while our binding was
saying that the allwinner,drive and allwinner,pull properties were
optional, the code was not able to deal with the case where they were not
present.

Changes from v1:
  - Realloced the pinctrl_map array
  - Detailed the generic properties we support
  - Directly return the parsing functions return code
  - Called kfree on the pinconfig directly
  - Added Chen-Yu Acked-by
  - Changed the patch 2 commit log as suggested

Maxime Ripard (9):
  pinctrl: sunxi: Rework the pin config building code
  pinctrl: sunxi: Use macros from bindings header file for DT parsing
  pinctrl: sunxi: Handle bias disable
  pinctrl: sunxi: Deal with configless pins
  pinctrl: sunxi: Support generic binding
  dt-bindings: pinctrl: Deprecate sunxi pinctrl bindings
  ARM: sunxi: Remove useless allwinner,drive property
  ARM: sunxi: Remove useless allwinner,pull property
  ARM: sunxi: Convert pinctrl nodes to generic bindings

Thanks for the clarification;

The proper approach is to remove the second independent gate
control from the divider.

This patch is not needed; the following patch resolve this issue:

I'd prefer that the naming is consistent across functions, even if it's left
as-is (and arguably cont makes it sounds like it doesn't cover block mappings).
So unless we find a suitably-equipped thesaurus, as-is is probably fine.

Thanks,

You can look at it from two sides.

Either you try to switch to the new mode all the time, or you try to
do it only for MMC controllers (and their associated clocks) that
support it.

In the former case, you'll need to ignore a failure in the switch
(mostly if the clock doesn't support it) only for the MMC controllers
that do not have that mode. For the controllers that support it, you
cannot ignore that error anymore. So you have to have some way to
identify in which case you are.

And you need to have that in the former case too, so there's really no
way you can go without such a flag.

Yes.

My local branch is based on 4.8 and fixes a few of Marcel's
comments. I'm currently at ELCE, but I will push my local
stuff later in the hotel after verifying, that it works as
expected (luckily I brought N950 with me :)).

The work I push will not yet be using Rob's (Herring) work
based on serio (I'm working on that). I think his patches
should go in first, so that we avoid introducing userspace
API, that we do not really want (hciattach).

* [PATCH v4 9/9] arm64: dts: add Pine64 support
From: Maxime Ripard @ 2016-10-11 14:28 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.024e1b023e41efe548dc6a004f7a946408d5c9a2.1476196031.git-series.maxime.ripard@free-electrons.com>

From: Andre Przywara <andre.przywara@arm.com>

The Pine64 is a cost-efficient development board based on the
Allwinner A64 SoC.
There are three models: the basic version with Fast Ethernet and
512 MB of DRAM (Pine64) and two Pine64+ versions, which both
feature Gigabit Ethernet and additional connectors for touchscreens
and a camera. Or as my son put it: "Those are smaller and these are
missing." ;-)
The two Pine64+ models just differ in the amount of DRAM
(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
patches the DT accordingly we just need to provide one DT for the
Pine64+.

* [PATCH v4 7/9] arm64: dts: add Allwinner A64 SoC .dtsi
From: Maxime Ripard @ 2016-10-11 14:28 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.024e1b023e41efe548dc6a004f7a946408d5c9a2.1476196031.git-series.maxime.ripard@free-electrons.com>

From: Andre Przywara <andre.przywara@arm.com>

The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
and the typical tablet / TV box peripherals.
The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
the peripherals and the memory map.
Although the cores are proper 64-bit ones, the whole SoC is actually
limited to 4GB (including all the supported DRAM), so we use 32-bit
address and size cells. This has the nice feature of us being able to
reuse the DT for 32-bit kernels as well.
This .dtsi lists the hardware that we support so far.

* [PATCH v4 4/9] clk: sunxi-ng: Add minimums for all the relevant structures and clocks
From: Maxime Ripard @ 2016-10-11 14:28 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.024e1b023e41efe548dc6a004f7a946408d5c9a2.1476196031.git-series.maxime.ripard@free-electrons.com>

Modify the current clocks we have to be able to specify the minimum for
each clocks we support, just like we support the max.

* [PATCH v4 3/9] clk: sunxi-ng: Finish to convert to structures for arguments
From: Maxime Ripard @ 2016-10-11 14:28 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.024e1b023e41efe548dc6a004f7a946408d5c9a2.1476196031.git-series.maxime.ripard@free-electrons.com>

Some clocks still use an explicit list of arguments, which make it a bit
more tedious to add new parameters.

Convert those over to a structure pointer argument to add as many
arguments as possible without having to many noise in our patches, or a
very long list of arguments.

* [PATCH v4 2/9] clk: sunxi-ng: Remove the use of rational computations
From: Maxime Ripard @ 2016-10-11 14:28 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <cover.024e1b023e41efe548dc6a004f7a946408d5c9a2.1476196031.git-series.maxime.ripard@free-electrons.com>

While the rational library works great, it doesn't really allow us to add
more constraints, like the minimum.

Remove that in order to be able to deal with the constraints we'll need.
