The Arm Ltd board bindings are a bit unusual in that they define child nodes for various syscon's. The schemas are also incomplete as they lack constraints on having additional properties and some properties are missing. As the bindings for the different platforms only vary by compatibles, combine them into a single schema doc. Add the "arm,im-pd1-syscon" compatible which was not documented. Add "ranges", "#address-cells", and "#size-cells properties which were missing. With this, fix the error exposed in the register-bit-led binding.

2023-08-18dt-bindings: leds: Document pull-up supply for interrupt and I2CStephan Gerhold1-0/+6
Since the interrupt and I2C lines of AW2013 operate in open drain low active mode a pull-up supply is needed for correct operation. Unfortunately there is no ideal place to describe it in the DT: The pull-up needed for the I2C lines could be described on the I2C bus. However, the pull-up needed for the interrupt line belongs neither directly to the interrupt controller nor to AW2013. Since the AW2013 driver will be typically in control of the power management and interrupt masking it makes more sense to describe it inside the AW2013 device tree node. Add it to the AW2013 DT schema together with a comment that makes it clear what exactly it represents.

Normally, the maximum brightness is determined by the hardware, and this property is not required. This property is used to set a software limit. It could happen that an LED is made so bright that it gets damaged or causes damage due to restrictions in a specific system, such as mounting conditions. Note that this flag is mainly used for PWM-LEDs, where it is not possible to map brightness to current. Drivers for other controllers should use led-max-microamp.

make dtbs_check: arch/arm/boot/dts/renesas/r8a7742-iwg21d-q7.dtb: backlight: 'power-supply' is a required property From schema: Documentation/devicetree/bindings/leds/backlight/pwm-backlight.yaml As that backlight device node already has an "enable-gpios" property to control the power supplied to the backlight, it sounds a bit silly to have to add a "power-supply" property just to silence this warning. In addition, as of commit deaeeda2051fa280 ("backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive state"), the Linux driver considers the power supply optional. Fix this by synchronizing the bindings with actual driver behavior by making the "power-supply" optional.

Commit e91a4d5deb96 ("dt-bindings: leds: Document commonly used LED triggers") introduced a enum match for cpu, while a pattern '^cpu[0-9]*$' already exists. This causes linux,default-trigger = "cpu" to have more than one match and generates the following dtbs_check warning: arch/arm64/boot/dts/ti/k3-j721e-beagleboneai64.dtb: leds: led-2:linux,default-trigger: More than one condition true in oneOf schema: {'$ref': '/schemas/types.yaml#/definitions/string', 'oneOf': [{'items': [{'enum': ['backlight', 'default-on', 'heartbeat', 'disk-activity', 'disk-read', 'disk-write', 'timer', 'pattern', 'audio-micmute', 'audio-mute', 'bluetooth-power', 'cpu', 'flash', 'kbd-capslock', 'mtd', 'nand-disk', 'none', 'torch', 'usb-gadget', 'usb-host', 'usbport']}], 'maxItems': 1, 'minItems': 1, 'type': 'array'}, {'items': [{'pattern': '^cpu[0-9]*$'}], 'maxItems': 1, 'minItems': 1, 'type': 'array'}, {'items': [{'pattern': '^hci[0-9]+-power$'}], 'maxItems': 1, 'minItems': 1, 'type': 'array'}, {'items': [{'pattern': '^mmc[0-9]+$'}], 'maxItems': 1, 'minItems': 1, 'type': 'array'}, {'items': [{'pattern': '^phy[0-9]+tx$'}], 'maxItems': 1, 'minItems': 1, 'type': 'array'}]} Drop the explicit match against cpu since the pattern match already covers the same.

2023-03-16dt-bindings: leds: Add "usbport" triggerRafał Miłecki1-0/+2
Linux's "usbport" trigger is a bit specific one. It allows LED to follow state of multiple USB ports which have to be selected additionally (there isn't a single trigger for each port). Default list of USB ports to monitor can be specified using "trigger-sources" DT property. Theoretically it should be possible for Linux to deduce applicable trigger based on the references nodes in the "trigger-sources". It hasn't been implemented however (probably due to laziness). Milk spilled - we already have DT files specifying "usbport" manually - allow that value in the binding. This fixes validation of in-kernel and external DT files.

SPI and I2C bus node names are expected to be "spi" or "i2c", respectively, with nothing else, a unit-address, or a '-N' index. A pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these cases. Mostly scripted with the following commands: git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/' git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/' With this, a few errors in examples were exposed and fixed.
