Pull LED updates from Pavel Machek: "This contains usual small updates to drivers, and removal of PAGE_SIZE limits on /sys/class/leds/<led>/trigger. We should not be really having that many triggers; but with cpu activity triggers we do, and we'll eventually need to fix it, but... remove the limit for now" * tag 'leds-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/pavel/linux-leds: (26 commits) leds: trigger: netdev: fix handling on interface rename leds: an30259a: add a check for devm_regmap_init_i2c leds: mlxreg: Fix possible buffer overflow leds: pca953x: Use of_device_get_match_data() leds: core: Fix leds.h structure documentation leds: core: Fix devm_classdev_match to reference correct structure leds: core: Remove extern from header leds: lm3601x: Convert class registration to device managed leds: flash: Add devm_* functions to the flash class leds: flash: Remove extern from the header file leds: flash: Convert non extended registration to inline leds: Kconfig: Be consistent with the usage of "LED" leds: remove PAGE_SIZE limit of /sys/class/leds/<led>/trigger leds: tlc591xx: update the maximum brightness leds: lm3692x: Use flags from LM3692X_BRT_CTRL leds: lm3692x: Use flags from LM3692X_BOOST_CTRL leds: lm3692x: Handle failure to probe the regulator leds: lm3692x: Don't overwrite return value in error path leds: lm3692x: Print error value on dev_err leds: tlc591xx: use devm_led_classdev_register_ext() ...

Crane Merchandising System - EL15203000 LED driver
|
||||
--------------------------------------------------
|
||||
|
||||
This LED Board (aka RED LEDs board) is widely used in
|
||||
coffee vending machines produced by Crane Merchandising Systems.
|
||||
The board manages 3 LEDs and supports predefined blinking patterns
|
||||
for specific leds.
|
||||
|
||||
Vending area LED encoded with symbol 'V' (hex code 0x56).
|
||||
Doesn't have any hardware blinking pattern.
|
||||
|
||||
Screen light tube LED which surrounds vending machine screen and
|
||||
encoded with symbol 'S' (hex code 0x53). Supports blinking breathing pattern.
|
||||
|
||||
Water Pipe LED encoded with symbol 'P' (hex code 0x50) and
|
||||
actually consists of 5 LEDs that exposed by protocol like one LED.
|
||||
Supports next patterns:
|
||||
- cascade pattern
|
||||
- inversed cascade pattern
|
||||
- bounce pattern
|
||||
- inversed bounce pattern
|
||||
|
||||
Required properties:
|
||||
- compatible : "crane,el15203000"
|
||||
- #address-cells : must be 1
|
||||
- #size-cells : must be 0
|
||||
|
||||
Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
|
||||
apply. In particular, "reg" and "spi-max-frequency" properties must be given.
|
||||
|
||||
Optional LED sub-node properties:
|
||||
- function:
|
||||
see Documentation/devicetree/bindings/leds/common.txt
|
||||
- color:
|
||||
see Documentation/devicetree/bindings/leds/common.txt

Example
|
||||
-------
|

#include <dt-bindings/leds/common.h>

|
||||
reg = <0>;
|
||||
spi-max-frequency = <50000>;
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
|
||||
/* water pipe */
|
||||
led@50 {
|
||||
reg = <0x50>;
|
||||
function = "pipe";
|
||||
color = <LED_COLOR_ID_RED>;
|
||||
};
|
||||
|
||||
/* screen frame */
|
||||
led@53 {
|
||||
reg = <0x53>;
|
||||
function = "screen";
|
||||
color = <LED_COLOR_ID_RED>;
|
||||
};
|
||||
|
||||
/* vending area */
|
||||
led@56 {
|
||||
reg = <0x56>;
|
||||
function = "vend";
|
||||
color = <LED_COLOR_ID_RED>;
|
||||
};
|
