* [PATCH 2/9] armv8: pm: Fix issue of rcpm driver wrongly program other IP control bits
From: Yinbo Zhu @ 2018-05-11 3:35 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180511033530.7931-1-yinbo.zhu@nxp.com>
From: Ran Wang <ran.wang_1@nxp.com>
When rcpm driver get target register data from DTS property 'fsl,
rcpm-wakeup' (second value), it directly write that data to register
RCPM_IPPDEXPCRx rather than 'OR' the value read from it before. This
operation will over-write those non-related IP control bit which
might have been programmed, should be prevented.

* Applied "soc: qcom dt-bindings: Add APR bus bindings" to the asoc tree
From: Mark Brown @ 2018-05-11 3:19 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180426094606.4775-2-srinivas.kandagatla@linaro.org>
The patch
soc: qcom dt-bindings: Add APR bus bindings
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

+Qualcomm APR (Asynchronous Packet Router) binding
+
+This binding describes the Qualcomm APR. APR is a IPC protocol for
+communication between Application processor and QDSP. APR is mainly
+used for audio/voice services on the QDSP.
+
+- compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
+
+- reg
+ Usage: required
+ Value type: <u32>
+ Definition: Destination processor ID.
+ Possible values are :
+ 1 - APR simulator
+ 2 - PC
+ 3 - MODEM
+ 4 - ADSP
+ 5 - APPS
+ 6 - MODEM2
+ 7 - APPS2
+
+= APR SERVICES
+Each subnode of the APR node represents service tied to this apr. The name
+of the nodes are not important. The properties of these nodes are defined
+by the individual bindings for the specific service
+- All APR services MUST contain the following property:
+
+- reg
+ Usage: required
+ Value type: <u32>
+ Definition: APR Service ID
+ Possible values are :
+ 3 - DSP Core Service
+ 4 - Audio Front End Service.
+ 5 - Voice Stream Manager Service.
+ 6 - Voice processing manager.
+ 7 - Audio Stream Manager Service.
+ 8 - Audio Device Manager Service.
+ 9 - Multimode voice manager.
+ 10 - Core voice stream.
+ 11 - Core voice processor.
+ 12 - Ultrasound stream manager.
+ 13 - Listen stream manager.
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.
+

* Applied "soc: qcom: Add APR bus driver" to the asoc tree
From: Mark Brown @ 2018-05-11 3:18 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180501120820.11016-3-srinivas.kandagatla@linaro.org>
The patch
soc: qcom: Add APR bus driver
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,

Subject: [PATCH] soc: qcom: Add APR bus driver
This patch adds support to APR bus (Asynchronous Packet Router) driver.
APR driver is made as a bus driver so that the apr devices can added removed
more dynamically depending on the state of the services on the dsp.
APR is used for communication between application processor and QDSP to
use services on QDSP like Audio and others.

* [PATCH v2] bpf, arm32: Correct check_imm24
From: Wang YanQing @ 2018-05-11 3:06 UTC (permalink / raw)
To: linux-arm-kernel
imm24 is signed, so the right range is:
[-(1<<(24 - 1)), (1<<(24 - 1)) - 1]
Note:this patch also fix a typo.
Signed-off-by: Wang YanQing <udknight@gmail.com>

Changes
v1-v2:
1:Rewrite the patch, I make a mistake, the v1 is wrong totally,
reported by Russell King.
I use the fix suggested by Russell King instead of myself which
use the exact number range [-8388608, 8388607].
2:Fix the error in changelog.
Thanks!

* [PATCH 2/2] arm64: dts: allwinner: h5: Update Orange Pi Zero Plus
From: Samuel Holland @ 2018-05-11 3:01 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20180511030124.9356-1-samuel@sholland.org>
The Orange Pi Zero Plus has an additional LED that was missing from the
device tree, and the power sequence for the SDIO Wi-Fi was missing.
The board also has UARTs 1, 2, and 3 exposed on a 26-pin GPIO header. As
the header is not populated by the manufacturer, disable the UARTs by
default.
Additionally, fix up an incorrect comment, remove an unnecessary header
inclusion, sort existing nodes, and fix some indentation issues.
