Subject: realtek: remove hardcoded sys-led configurations
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eae5e55a7938504691f8be27665c6fa3935a01d9;p=openwrt%2Fstaging%2Fjow.git

realtek: remove hardcoded sys-led configurations

setup.c unconditionally sets the sys-led mode (blinking rate) to a
permanent high output. This may cause issues when a board expects this
pin to toggle periodically, e.g. when hooked up to an external watchdog.

If the sys-led peripheral is used to control an LED, the mux should be
configured to use the pin as GPIO0, allowing for better control as a
GPIO LED.
