The Samsung MIPI D-/C-PHY block on RK3588 drives a MIPI DSI transmitter
and, on the same PHY, can receive a MIPI CSI camera. Describing both as
independent consumers of one PHY requires the direction to be expressed
in the devicetree.
Allow "#phy-cells" to be 1 or 2. The existing single-cell form still
selects the PHY type and refers to the transmitter, so shipped DSI
device trees stay valid; bumping the cell count unconditionally would
invalidate them. A second cell adds the direction, letting a DSI (TX)
and a CSI (RX) reference the same PHY node as separate consumers.
Add include/dt-bindings/phy/rockchip,rk3588-mipi-dcphy.h for the
RK_DCPHY_DIR_TX and RK_DCPHY_DIR_RX direction constants.
