[PATCH v3 2/5] phy: rockchip: phy-rockchip-typec: Add typec_mux/typec_switch support
Posted by Chaoyi Chen 2 months, 1 week ago
From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

This patch add support for Type-C Port Controller Manager. Each PHY
will register typec_mux and typec_switch when external Type-C
controller is present. Type-C events are handled by TCPM without
extcon.

The extcon device should still be supported.

Signed-off-by: Chaoyi Chen <chaoyi.chen@rock-chips.com>
---

Changes in v2:
- Fix compile error when CONFIG_TYPEC is not enabled.
- Notify DP HPD state by USB/DP PHY.
