cover Add support for WL-ICLEDs from Wurth Elektronik

From: Ante Knezic <[email protected]>

This patch adds support for WL-ICLED series of RGB Leds. These LEDs are equipped with integrated controller and can be daisy chained to arbitrary number of units. The MCU communicates with the first LED in series via SPI. Interface can be regular SPI protocol or single line only (MOSI connection only) depending on the model.

+Description
+-----------
+The WL-ICLEDs are RGB LEDs with integrated controller that can be
+daisy-chained to a arbitrary number of units. The MCU communicates
+with the first LED in chain via SPI interface and can be single or
+two wire connection, depending on  the model.
+
+Single wire models like 1315050930002, 1313210530000, 1312020030000 and
+1312121320437 are controlled with specific signal pattern on the
+input line. The MCU is connected to input line only via SPI MOSI signal.
+For example WE-1312121320437 uses following signal pattern per one LED:
+
+|          RED            |          GREEN          |           BLUE          |
+| GAIN:4bits | PWM:12bits | GAIN:4bits | PWM:12bits | GAIN:4bits | PWM:12bits |
+
+ where logical 1 is represented as:
+ (V)^

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

Unfortunatelly, yes. Exact model names are quite elaborate, yet similar enough:

1315050930246   --> we,1315x246
1315050930002   --> we,1315x002
1313210530000   --> we,131x000

1312020030000 we,131x000
1311610030140 --> we,131161x
1312121320437 --> we,131212x

This seemed easier than writing complete model number... You want compatible expanded to full number anyway?

driver as Linux driver? Then drop and describe hardware.

Quoted 2 lines

Sorry, I am not sure I quite understand what you mean here? Add "linux LED driver" to title?

I am asking to drop it and instead describe the hardware.

Also drop full stop

Ok, understood.

+  The WL-ICLEDs are RGB LEDs with integrated controller that can be
+  daisy-chained to arbitrary number of LEDs. Communication with LEDs is
+  via SPI interface and can be single or two wire, depending on the model.

+      - we,131161x
+      - we,131212x

Is that a wildcard in each compatible?

Unfortunatelly, yes. Exact model names are quite elaborate, yet similar enough:

1315050930246   --> we,1315x246
1315050930002   --> we,1315x002
1313210530000   --> we,131x000

1312020030000 we,131x000
1311610030140 --> we,131161x
1312121320437 --> we,131212x

This seemed easier than writing complete model number... You want compatible expanded to full number anyway?

Yes, otherwise git grep for model won't work.

Best regards,

PATCH 3/3 leds: add WL-ICLED SPI driver

In reply to Ante Knezic

From: Ante Knezic <[email protected]>

Add support for WL-ICLED RGB LEDs with integrated controller. Device enables individual color control via SPI interface and can be interfaced via single wire connection (MOSI line only) or by two wire connection (MOSI and CLK).
