Subject: [PATCH 2/2] ARM: dts: bcm2711-rpi: enable USB and skip soft reset wait on RPi4
Date: Mon, 30 Mar 2026 23:17:23 -0400 [thread overview]
Message-ID: <20260331031723.195128-2-chalianis1@gmail.com> (raw)
In-Reply-To: <20260331031723.195128-1-chalianis1@gmail.com>
From: Chali Anis <chalianis1@gmail.com>
The dwc2 controller on bcm2711 does not reliably deassert GRSTCTL_CSFTRST
within the expected window, causing probe to fail with ETIMEDOUT. Enable
the USB node and set no-csftrst-wait to bypass the reset bit polling.
