phy: Add MediaTek UFS PHY Driver

2026-03-02T14:19:17+00:00

This UFS M-PHY driver can be used on recent MediaTek SoCs as the
primary PHY for the UFS controller.

dm: core: Default to using DEVRES outside of xPL

2026-01-09T15:08:14+00:00

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).

This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

phy: imx8mq-usb: Add SPL support for i.MX8MQ, i.MX8MP, i.MX95, and i.MX94 USB3.0 PHY

2025-11-04T15:39:46+00:00

This patch adds SPL Kconfig option (SPL_PHY_IMX8MQ_USB) for the i.MX8MQ,
i.MX8MP, i.MX95, and i.MX94 USB3.0 PHY driver, allowing the driver to be
compiled and probed in SPL stage.

phy: phy-imx8mq-usb: Add support for i.MX95 USB3 PHY

2025-08-23T16:17:48+00:00

Add initial support for i.MX95 USB.30 PHY, which is similar to
the i.MX8MQ and i.MX8MP USB PHY.

The i.MX95 USB3 PHY has a Type-C Assist block (TCA) consisting of two
functional blocks (XBar assist and VBus assist) and is documented
in the i.MX95 RM Chapter 163.3.8 Type-C assist (TCA) block.

Instead of relying on an external MUX for Type-C plug orientation the
XBar can handle the flip internally.

Add initial support for i.MX95 by:
 - allowing the driver to be enabled i.MX95
 - resetting the XBar
 - configuring the TCA in System Configuration mode (which was determined
   to be necessary to enable the PHY in device-mode)

Follow-on support will need to be added to steer the XBar based on
either board design (if only one pair is brought out) or if used with a
Type-C controller.

phy: samsung: Add Exynos USB DRD PHY driver

2025-07-25T01:17:21+00:00

Add DM driver for Exynos USB PHY controllers. For now it only supports
Exynos850 SoC. Only UTMI+ (USB 2.0) PHY interface is implemented, as
Exynos850 doesn't support USB 3.0. Only two clocks are used for this
controller:
  - phy: bus clock, used for PHY registers access
  - ref: PHY reference clock (OSCCLK)

phy: phy-mtk-tphy: add support for phy type switch

2024-07-08T17:45:50+00:00

Add support for PHY type switch via the mediatek topmisc syscon.

This is needed on mt7981 to make the PCIe correctly work and display
LinkUp.

Follow the same implementation done on Linux kernel with the usage of
the mediatek,syscon-type property.

Example:

u3port0: usb-phy@11e10700 {
	reg = <0x11e10700 0x900>;
	clocks = <&topckgen CK_TOP_USB3_PHY_SEL>;
	clock-names = "ref";
	#phy-cells = <1>;
	mediatek,syscon-type = <&topmisc 0x218 0>;
	status = "okay";
};
