Subject: [PATCH v2 1/5] dt-bindings: phy: rockchip: rk3399-typec-phy: Support mode-switch
Date: Fri, 18 Jul 2025 14:26:15 +0800 [thread overview]
Message-ID: <20250718062619.99-2-kernel@airkyi.com> (raw)
In-Reply-To: <20250718062619.99-1-kernel@airkyi.com>
From: Chaoyi Chen <chaoyi.chen@rock-chips.com>
The RK3399 has two USB/DP combo PHY. With the help of external Type-C
controller, the PHY can switch altmode between USB and DP.
Their connection diagram is shown below:
external Type-C Chip0 ---> USB/DP PHY0 ---+
| <----> CDN-DP controller
external Type-C Chip1 ---> USB/DP PHY1 ---+
This patch add new "mode-switch" property for dp-port to indicate
whether the PHY can handle altmode switching.
Signed-off-by: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Changes in v2:
- Reuse dp-port/usb3-port in rk3399-typec-phy binding.
