* dt-bindings: leds: Add pattern initialization from Device TreeKrzysztof Kozlowski2019-01-162-0/+61
| | | | | | | | | | | | Document new led-pattern property for initialization of LED triggers. The property format is trigger-specific (except being array of integers). For pattern trigger, the explanation of pattern format was moved to a common file shared with sysfs ABI.

|/ | | | | | | | | | | | | During my work on some new LED trigger I tried adding example similar to the existing ones which received following comment from Rob: > It's not really clear in the example this is an LED node as it is > incomplete. Keeping that in mind I suggest adding context for the existing example entries in hope to make documentation more clear.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LP8556 datasheet describes an EN/VDDIO input, which serves "both as a chip enable and as a power supply reference for PWM, SDA, and SCL inputs." The LP8556 that I'm testing doesn't respond properly if I try to talk I2C to it too quickly after enabling VDDIO, and the LP8555 datasheet mentions a t_RESPONSE delay of up to 1 millisecond. Support this EN/VDDIO by adding a regulator property to the binding; enabling this regulator at probe time; and sleeping for 1 to 2ms, if the EN/VDDIO regulator was provided.

This commit adds support for the new "panic-indicator" firmware property, allowing to mark a given LED to blink on a kernel panic.
