* [PATCH 2/8] power: add power sequence library
From: Peter Chen @ 2017-01-03 6:33 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483425211-14473-1-git-send-email-peter.chen@nxp.com>
We have an well-known problem that the device needs to do some power
sequence before it can be recognized by related host, the typical
example like hard-wired mmc devices and usb devices.
This power sequence is hard to be described at device tree and handled by
related host driver, so we have created a common power sequence
library to cover this requirement. The core code has supplied
some common helpers for host driver, and individual power sequence
libraries handle kinds of power sequence for devices. The pwrseq
librares always need to allocate extra instance for compatible
string match.
pwrseq_generic is intended for general purpose of power sequence, which
handles gpios and clocks currently, and can cover other controls in
future. The host driver just needs to call of_pwrseq_on/of_pwrseq_off
if only one power sequence is needed, else call of_pwrseq_on_list
/of_pwrseq_off_list instead (eg, USB hub driver).
For new power sequence library, it can add its compatible string
to pwrseq_of_match_table, then the pwrseq core will match it with
DT's, and choose this library at runtime.

* [PATCH 4/8] usb: core: add power sequence handling for USB devices
From: Peter Chen @ 2017-01-03 6:33 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483425211-14473-1-git-send-email-peter.chen@nxp.com>
Some hard-wired USB devices need to do power sequence to let the
device work normally, the typical power sequence like: enable USB
PHY clock, toggle reset pin, etc. But current Linux USB driver
lacks of such code to do it, it may cause some hard-wired USB devices
works abnormal or can't be recognized by controller at all.
In this patch, it calls power sequence library APIs to finish
the power sequence events. It will do power on sequence at hub's
probe for all devices under this hub (includes root hub).
At hub_disconnect, it will do power off sequence which is at powered
on list.

the glue layer's node is the parent node for host and udc

we let the core's device node equals glue layer device node.

The current dts describes USB HUB's property at USB controller's
entry, it is improper. The USB HUB should be the child node
under USB controller, and power sequence properties are under
it. Besides, using gpio pinctrl setting for USB2415's reset pin.

* [PATCH v4 1/3] soc: zte: pm_domains: Prepare for supporting ARMv8 zx2967 family
From: Baoyou Xie @ 2017-01-03 6:56 UTC (permalink / raw)
To: linux-arm-kernel
The ARMv8 zx2967 family (296718, 296716 etc) uses different value
for controlling the power domain on/off registers, Choose the
value depending on the compatible.
Multiple domains are prepared for the family, this patch prepares
the common functions.

* [PATCH v4 3/3] MAINTAINERS: add zx2967 SoC drivers to ARM ZTE architecture
From: Baoyou Xie @ 2017-01-03 6:56 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483426577-5470-1-git-send-email-baoyou.xie@linaro.org>
Add the ZTE SoC drivers as maintained by ARM ZTE
architecture maintainers, as they're parts of the core IP.
By the way, this patch adds the maintainer for ARM
ZTE architecture to Baoyou Xie.

The subject prefix is still not so right. There should be a space after
each colon.

The single line comment format is /* blabla */. There are space at both
beginning and end of the text.
Also I am asking that we use the single line comment to replace the
blank line, which is still there.

* [PATCH v6 06/14] irqchip: gicv3-its: platform-msi: refactor its_pmsi_init() to prepare for ACPI
From: Tomasz Nowicki @ 2017-01-03 7:41 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483363905-2806-7-git-send-email-hanjun.guo@linaro.org>
Hi,
Can we merge patch 4 & 6 into one patch so that we keep refactoring part
as one piece ? I do not see a reason to keep them separate or have patch
5 in between. You can refactor what needs to be refactored, add
necessary functions to iort.c and then support ACPI for
irq-gic-v3-its-platform-msi.c
Thanks,
Tomasz

I think keeping the newline makes it more clear in structure. But I also understand
your point - no newline inside one property, right? If so I will delete the newline.

* [PATCH 0/4] Add touch key driver support for TM2
From: Jaechul Lee @ 2017-01-03 7:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <CGME20170103075733epcas5p48985c789a816f1f2eae84c52e070cc14@epcas5p4.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.
dts has been separated between tm2 and tm2e because touchkey is present in tm2
but not tm2e.
Best Regards,
Jaechul

This patch adds support for the TM2 touch key and led
functionlity.
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".

* [PATCH 3/4] arm64: dts: exynos: make tm2 and tm2e independent from each other
From: Jaechul Lee @ 2017-01-03 7:57 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1483430237-26823-1-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.
