phy: sunplus: return negative error code in sp_usb_phy_probe

2023-11-27T13:09:18Z

devm_phy_create() return negative error code, 'ret' should be 'PTR_ERR(phy)' rather than '-PTR_ERR(phy)'.

phy: mediatek: mipi: mt8183: fix minimal supported frequency

2023-11-27T12:53:26Z

The lowest supported clock frequency of the PHY is 125MHz (see also mtk_mipi_tx_pll_enable()), but the clamping in .round_rate() has the wrong minimal value, which will make the .enable() op return -EINVAL on low frequencies. Fix the minimal clamping value.

phy: ti: gmii-sel: Fix register offset when parent is not a syscon node

2023-11-16T11:27:50Z

When the node for this phy selector is a child node of a syscon node then the property 'reg' is used as an offset into the parent regmap. When the node is standalone and gets its own regmap this offset is pre-applied. So we need to track which method was used to get the regmap and not apply the offset in the standalone case.

Revert "phy: realtek: usb: Add driver for the Realtek SoC USB 2.0 PHY"

2023-11-06T13:47:36Z

This reverts commit 134e6d25f6bd06071e5aac0a7eefcea6f7713955. The recently added Realtek PHY drivers depend on the new port status notification mechanism which was built on the deprecated USB PHY implementation and devicetree binding. Specifically, using these PHYs would require describing the very same PHY using both the generic "phy" property and the deprecated "usb-phy" property which is clearly wrong. We should not be building new functionality on top of the legacy USB PHY implementation even if it is currently stuck in some kind of transitional limbo. Revert the new Realtek PHY drivers for now so that the port status notification interface can be reverted and replaced.

phy: Kconfig: Select GENERIC_PHY for GENERIC_PHY_MIPI_DPHY

2023-10-23T06:24:49Z

GENERIC_PHY can be selected by GENERIC_PHY_MIPI_DPHY directly as GENERIC_PHY has no dependencies. This way drivers that depend on GENERIC_PHY_MIPI_DPHY can avoid having to select both --- which they apparently often omit, too, which further leads to build failures.
