From dac0a133cf8dbf0bd9afabecdc1092456c451ec7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pavel=20Perni=C4=8Dka?= Date: Tue, 27 Jun 2023 18:34:03 +0200 Subject: [PATCH] ath79: DTS improvement for buzzer on RB951G-2HnD MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Mikrotik RB951 router has a buzzer on the board, which makes annoying noises due to the interference caused by PoE input or Wifi transmission when no GPIO pin state is set. I added buzzer node to device's DTS in order to set deault level to 1 and to provide easier access for it.
