Subject: [PATCH] leds: core: add OF variants of LED registering functions
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
These new functions allow passing an additional device_node argument
|
|
that will be internally set for created LED device. Thanks to this LED
|
|
core code and triggers will be able to access DT node for reading extra
|
|
info.
|
|
|
|
The easiest solution for achieving this was reworking old functions to
|
|
more generic ones & adding simple defines for API compatibility.
