[PATCH v4 1/7] dt-bindings: phy: Add PHY_TYPE_DSI and PHY_TYPE_CSI definitions

[Jason Yang via B4 Relay]

From: Jason Yang <jason98166 at gmail.com>

A MIPI D-PHY or C-PHY can be a transmitter (DSI) or a receiver (CSI),
and in some PHY blocks both work at the same time. The existing
PHY_TYPE_DPHY and PHY_TYPE_CPHY cannot tell whether a consumer wants
the transmitter or the receiver.

Add PHY_TYPE_DSI and PHY_TYPE_CSI, so that a binding can select both
D-PHY or C-PHY and transmitter or receiver. They do not replace
PHY_TYPE_DPHY/PHY_TYPE_CPHY, which remain the right choice where a cell
selects the mode. The first user is the Rockchip RK3588 MIPI DC-PHY
binding.
