* [PATCH v2 6/8] crypto: arm64/aes-neon - fix for big endian
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476209720-21114-1-git-send-email-ard.biesheuvel@linaro.org>

The AES implementation using pure NEON instructions relies on the generic
AES key schedule generation routines, which store the round keys as arrays
of 32-bit quantities stored in memory using native endianness. This means
we should refer to these round keys using 4x4 loads rather than 16x1 loads.
In addition, the ShiftRows tables are loading using a single scalar load,
which is also affected by endianness, so emit these tables in the correct
order depending on whether we are building for big endian or not.

* [PATCH v2 5/8] crypto: arm64/aes-ccm-ce: fix for big endian
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476209720-21114-1-git-send-email-ard.biesheuvel@linaro.org>

The AES-CCM implementation that uses ARMv8 Crypto Extensions instructions
refers to the AES round keys as pairs of 64-bit quantities, which causes
failures when building the code for big endian. In addition, it byte swaps
the input counter unconditionally, while this is only required for little
endian builds. So fix both issues.

* [PATCH v2 4/8] crypto: arm64/sha2-ce - fix for big endian
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476209720-21114-1-git-send-email-ard.biesheuvel@linaro.org>

The SHA256 digest is an array of 8 32-bit quantities, so we should refer
to them as such in order for this code to work correctly when built for
big endian. So replace 16 byte scalar loads and stores with 4x32 vector
ones where appropriate.

* [PATCH v2 2/8] crypto: arm64/ghash-ce - fix for big endian
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476209720-21114-1-git-send-email-ard.biesheuvel@linaro.org>

The GHASH key and digest are both pairs of 64-bit quantities, but the
GHASH code does not always refer to them as such, causing failures when
built for big endian. So replace the 16x1 loads and stores with 2x8 ones.

* [PATCH v2 1/8] crypto: arm64/aes-ce - fix for big endian
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476209720-21114-1-git-send-email-ard.biesheuvel@linaro.org>

The core AES cipher implementation that uses ARMv8 Crypto Extensions
instructions erroneously loads the round keys as 64-bit quantities,
which causes the algorithm to fail when built for big endian. In
addition, the key schedule generation routine fails to take endianness
into account as well, when loading the combining the input key with
the round constants. So fix both issues.

* [PATCH v2 0/8] crypto: ARM/arm64 - big endian fixes
From: Ard Biesheuvel @ 2016-10-11 18:15 UTC (permalink / raw)
  To: linux-arm-kernel

As it turns out, none of the accelerated crypto routines under arch/arm64/crypto
currently work, or have ever worked correctly when built for big endian. So this
series fixes all of them. This v2 now includes a similar fix for 32-bit ARM as
well, and an additional fix for XTS which escaped my attention before.

Each of these patches carries a fixes tag, and could be backported to stable.
However, for patches #1 and #5, the fixes tag denotes the oldest commit that the
fix is compatible with, not the patch that introduced the algorithm. This is due
to the fact that the key schedules are incompatible between generic AES and the
arm64 Crypto Extensions implementation (but only when building for big endian)
This is not a problem in practice, but it does mean that the AES-CCM and AES in
EBC/CBC/CTR/XTS mode implementations before v3.19 require a different fix, i.e.,
one that is compatible with the generic AES key schedule generation code (which
it currently no longer uses)

In any case, please apply with cc to stable.

That's good news. Thanks for testing.

* [PATCH] ARM: imx: gpc: Initialize all power domains
From: Fabio Estevam @ 2016-10-11 17:53 UTC (permalink / raw)
  To: linux-arm-kernel

When booting a kernel built with multi_v7_defconfig the following
probe error is seen:

imx-gpc: probe of 20dc000.gpc failed with error -22

Later on the kernel crashes like this:

The gpc probe fails because of_genpd_add_provider_onecell() checks
if all the domains are initialized via pm_genpd_present() function
and it returns an error on the multi_v7_defconfig case.

In order to fix this error, initialize all the imx_gpc_domains, not
only the imx6q_pu_domain.base one.

With the patches applied, the pixel clock (148500000 required for 1920x1080 at 60) is correct as we checked in kernel 4.7 and the actual measurement result looked good as we expected.
I think the patches should fix the issue.

Please extend ili210x.c instead of adding brand new driver, they look
very similar.

Thanks.

Please could you keep the people who reviewed/commented on your series in the past,
whenever you post a new version ?

Could these go to a header file, so that we don't need duplicate definitions of these helpers in
different files ?

What format is the (timestamp + 3) stored in ? Does it need conversion ?

minor nit: Would it be easier to order/parse the error messages if the date
is printed first followed by time ?

i.e,
	17:20:14 2016-09-15 Mon
		vs
	2016-09-15 Mon 17:20:14

e.g, people looking at a huge log, looking for logs from a specific date might
find the latter more useful to skip the messages.

Could we use the helper defined above ?

Same as above, use the macro ?

As mentioned in the previous version, would it make sense to add some more
helpers to deal with record versions ? We seem to be doing the version switch and
code duplication at different places.

Does the following help ? Thoughts ?

#define acpi_hest_generic_data_error_length(gdata) (((struct acpi_hest_generic_data *)(gdata))->error_data_length)
#define acpi_hest_generic_data_size(gdata) \
	((acpi_hest_generic_data_version(gdata) >= 3) ? \
	 sizeof(struct acpi_hest_generic_data_v300) :	\
	 sizeof(struct acpi_hest_generic_data))
#define acpi_hest_generic_data_record_size(gdata)
	(acpi_hest_generic_data_size(gdata) + \
	 acpi_hest_generic_data_error_length(gdata))
#define acpi_hest_generic_data_next(gdata) \
	((void *)(gdata) + acpi_hest_generic_data_record_size(gdata))

Yes, that resembles my own calculations. Another complication is that
folded PUDs and PMDs need to be dealt with at the PGD level, but I
think I have worked it out now.

Re 16 GB: are you saying don't bother? Because supporting this would
require ARM64_MEMSTART_SHIFT to be increased to (CONT_PUD_SHIFT +
PUD_SHIFT) or (CONT_PMD_SHIFT + PMD_SHIFT) [for 4k and 16k/64k,
respectively] in order to guarantee that the physical and virtual
addresses are always equal modulo 16 GB (for granules that support
it). It's a nice idea that the linear mapping can be covered by fewer
TLB entries if you have huge amounts of RAM, but if the hardware is
unlikely to honour it, it may not be worth the trouble.

I see you're going to work on a more comprehensive v3 (thanks!), but just
to help clarify this: the contiguous bit is valid whenever a block or page
(i.e. a leaf) entry is valid. The only complication with 16k pages is that
the number of contiguous entries changes between level 2 and level 3,
which makes sense if you think about the TLB entries supported due to
non-contiguous block mappings in other regimes anyway (and brings into
question whether people bother with 16G in practice).

That means you can use the contiguous bit as:

4k: levels 1,2,3 (16G, 32M, 64K)
16k: levels 2,3 (1G, 2M)
64k: levels 2,3 (16G, 2M)

Hopefully my maths is correct and that clears things up,

* [PATCH v6 2/2] i2c: qup: support SMBus block read
From: Austin Christ @ 2016-10-11 16:27 UTC (permalink / raw)
  To: linux-arm-kernel
In-Reply-To: <1476203277-6893-1-git-send-email-austinwc@codeaurora.org>

From: Naveen Kaje <nkaje@codeaurora.org>

I2C QUP driver relies on SMBus emulation support from the framework.
To handle SMBus block reads, the driver should check I2C_M_RECV_LEN
flag and should read the first byte received as the message length.

The driver configures the QUP hardware to read one byte. Once the
message length is known from this byte, the QUP hardware is configured
to read the rest.

* [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

  i2c: qup: add ACPI support
  i2c: qup: support SMBus block read

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.

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

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

  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.
