In-Reply-To: <20180815095934.11205-1-enric.balletbo@collabora.com> References: <20180815095934.11205-1-enric.balletbo@collabora.com> Message-ID: <20180815095934.11205-3-enric.balletbo@collabora.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Commit 98898f3bc83c8 ("phy: rockchip-inno-usb2: support otg-port for rk3399") introduces two new properties. The extcon property is used to detect the cable-state, and the rockchip,utmi-avalid is used to indicate which register should be used to detect the vbus state. Document these properties in the documentation binding.
