8 title: MediaTek T-PHY Controller
11 - Chunfeng Yun <chunfeng.yun@mediatek.com>
14 The T-PHY controller supports physical layer functionality for a number of
15 controllers on MediaTek SoCs, includes USB2.0, USB3.0, PCIe and SATA.
17 Layout differences of banks between T-PHY V1 (mt8173/mt2701) and
18 T-PHY V2 (mt2712) / V3 (mt8195) when works on USB mode:

103 T-PHY V2/V3, such as mt2712.

240 The force mode is used to manually switch the shared phy mode between
241 USB3 and PCIe, when USB3 phy type is selected by the consumer, and
242 force-mode is set, will cause phy's power and pipe toggled and force
243 phy as USB3 mode which switched from default PCIe mode. But perfer to
244 use the property "mediatek,syscon-type" for newer SoCs that support it.
