In case a PHY LED implements .blink_set callback to set LED blink interval, call it even if .hw_control is already set, as that LED blink interval likely controls the blink rate of that HW offloaded LED. For PHY LEDs, that can be their activity blinking interval. The software blinking is not affected by this change. With this change, the LED interval setting looks something like this: $ echo netdev > /sys/class/leds/led:green:lan/trigger $ echo 1 > /sys/class/leds/led:green:lan/brightness $ echo 250 > /sys/class/leds/led:green:lan/interval Signed-off-by: Marek Vasut <marex@denx.de> Link: https://lore.kernel.org/r/20250120113740.91807-1-marex@denx.de Signed-off-by: Lee Jones <lee@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
