Merge tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds
Pull LED updates from Jacek Anaszewski:
"We introduce LED pattern trigger - the idea that was proposed three
years ago now received enough attention and determination to drive it
to the successful end.
There is also one new LED class driver and couple of improvements to
the existing ones.
New LED class driver:
- add support for Panasonic AN30259A with related DT bindings
New LED trigger:
- introduce LED pattern trigger
leds-sc27xx-bltc:
- implement pattern_set/clear ops to enable support for pattern
trigger's hw_pattern sysfs file
Improvements to existing LED class drivers:
- leds-pwm: don't print error message on -EPROBE_DEFER
- leds-gpio: try to lookup gpiod from device
- leds-as3645a: convert to using %pOFn instead of device_node.name"
* tag 'leds-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds:
leds: sc27xx: Add pattern_set/clear interfaces for LED controller
leds: core: Introduce LED pattern trigger
leds: add Panasonic AN30259A support
dt-bindings: leds: document Panasonic AN30259A bindings
leds: gpio: Try to lookup gpiod from device
leds: pwm: silently error out on EPROBE_DEFER
leds: Convert to using %pOFn instead of device_node.name
Core changes:
- A patch series from Hans Verkuil to make it possible to
enable/disable IRQs on a GPIO line at runtime and drive GPIO
lines as output without having to put/get them from scratch.
The irqchip callbacks have been improved so that they can
use only the fastpatch callbacks to enable/disable irqs
like any normal irqchip, especially the gpiod_lock_as_irq()
has been improved to be callable in fastpath context.
A bunch of rework had to be done to achieve this but it is
a big win since I never liked to restrict this to slowpath.
The only call requireing slowpath was try_module_get() and
this is kept at the .request_resources() slowpath callback.
In the GPIO CEC driver this is a big win sine a single
line is used for both outgoing and incoming traffic, and
this needs to use IRQs for incoming traffic while actively
driving the line for outgoing traffic.
- Janusz Krzysztofik improved the GPIO array API to pass a
"cookie" (struct gpio_array) and a bitmap for setting or
getting multiple GPIO lines at once. This improvement
orginated in a specific need to speed up an OMAP1 driver and
has led to a much better API and real performance gains
when the state of the array can be used to bypass a lot
of checks and code when we want things to go really fast.
The previous code would minimize the number of calls
down to the driver callbacks assuming the CPU speed was
orders of magnitude faster than the I/O latency, but this
assumption was wrong on several platforms: what we needed
to do was to profile and improve the speed on the hot
path of the array functions and this change is now
completed.
- Clean out the painful and hard to grasp BNF experiments
from the device tree bindings. Future approaches are looking
into using JSON schema for this purpose. (Rob Herring
is floating a patch series.)
New drivers:
- The RCAR driver now supports r8a774a1 (RZ/G2M).
- Synopsys GPIO via CREGs driver.
Major improvements:
- Modernization of the EP93xx driver to use irqdomain and
other contemporary concepts.
- The ingenic driver has been merged into the Ingenic pin
control driver and removed from the GPIO subsystem.
- Debounce support in the ftgpio010 driver.

descriptor API, there's a small addition to the GPIO API plus a bunch of
updates to board files to implement it. This is some really welcome
work from Linus Walleij that's had a bunch of review and has been
sitting in -next for a while so I'm fairly happy there's no major
issues.

- Display opmode and consumer requested load in the regualtor_summary

- Support for the fun and entertaining power off mechanism that the
pfuze100 hardware implements.

The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community. Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it. We also do not expect this interpretation
to be static over time, and will adjust it as needed.
This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

This compatible adds the ability for dw spi controller driver to work with
the dw spi controller found on Alpine chips.
The dw spi controller has an auto-deselect of Chip-Select, in case there is
no data inside the Tx FIFO. While working on platforms with Alpine chips,
auto-deselect mode causes an issue for some spi devices that can't handle
the Chip-Select deselect in the middle of a transaction. It is a normal
behavior for a Tx FIFO to be empty in the middle of a transaction, due to
busy cpu. In the Alpine chip family an option to change the default
behavior was added to the original dw spi controller to prevent this issue
of de-asserting Chip-Select once TX FIFO is empty. The change was to allow
SW manual control of the Chip-Select. With this change, as long as the
Slave Enable Register is asserted, the Chip-Select will be asserted. As a
result, it is necessary to deselect the Slave Select Register once the
transaction is done. This feature is enabled via a new device compatible
string called 'amazon,alpine-dw-apb-ssi'. Once the driver identifies the
new compatible string, it enables the hw fixup logic, by writing to a
dedicated register found in the IP reserved area and will start manual
deselecting the Slave Select Register when the transfer ends.

An ina3221 chip has three input ports. Each port is used
to measure the voltage and current of its input source.
The DT binding now has defined bindings for their input
sources, so the driver should read these information and
handle accordingly.
This patch adds a new structure of input source specific
information including input source label, shunt resistor
value and its connection status. It exposes these labels
via in[123]_label sysfs nodes upon available, and also
disables those channels where there are no input source
being connected. Meanwhile, it also adds in[123]_enable
sysfs nodes for users to get control of three channels,
and returns -ENODATA code for any sensor read according
to hwmon ABI.
