Subject: [PATCH v4 1/3] dt-bindings: phy: add binding document for Allwinner F1C100s USB PHY
Date: Wed, 16 Nov 2022 15:16:01 +0000 [thread overview]
Message-ID: <20221116151603.819533-2-andre.przywara@arm.com> (raw)
In-Reply-To: <20221116151603.819533-1-andre.przywara@arm.com>
From: Icenowy Zheng <uwu@icenowy.me>
Allwinner F1C100s has the most simple USB PHY among all Allwinner SoCs,
because it has only one OTG USB controller, no host-only OHCI/EHCI
controllers.
Add a binding document for it. Following the current situation of one
YAML file per SoC, this one is based on
allwinner,sun8i-v3s-usb-phy.yaml, but with OHCI/EHCI-related bits
removed. (The same driver in Linux, phy-sun4i-usb, covers all these
binding files now.)
