Mon Dec 19 07:43:52 CET 2022
From: Fabien Parent <fparent at baylibre.com>
The MediaTek MT8195 is a ARM64-based SoC with a quad-core Cortex-A73 and
a quad-core Cortex-A53. It is including UART, SPI, USB3.0 device and hosts,
SD and MMC cards, UFS, PWM, I2C, I2S, S/PDIF, and several LPDDR3
and LPDDR4 options.

Changes for v2:
- Correct node name to t-phy for u3phy0.
- Add platform compatible string "mediatek,mt8195-tphy" to all usb phy nodes.
- remove clock nodes that software cannot controlled in phy nodes.
- Test and add back "mac" for HOST only xhci nodes.
Changes for v3:
- Revise device node name from "xhciX: xhciX@" to "xhciX: xhci@".
Changes for v4:
- No change.
