Subject: [PATCH 6/9] dt-bindings: usb: generic-ehci: Add the NSP compatible
Date: Wed, 21 Oct 2026 10:28:15 -0700 [thread overview]
Message-ID: <20261021172819.668120-7-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20261021172819.668120-1-florian.fainelli@broadcom.com>
Describe the EHCI controller in Broadcom Northstar Plus SoCs with a
SoC-specific compatible. It needs the same FIFO threshold programming
as other iProc EHCI controllers, which generic-ehci alone cannot select.
