phy: samsung: usb2: drop unused module alias

2025-08-13T06:49:25+00:00

The driver has never supported anything but OF probe so drop the unused
platform module alias.

phy: exynos-mipi-video: correct cam0 sysreg property name for exynos7870

2025-07-22T13:14:51+00:00

Fix the cam0 sysreg property name (samsung,cam0-sysreg), which has been
erroneously declared as samsung,cam-sysreg. This follows the same name
used in Exynos5433 PHY.

phy: exynos5-usbdrd: Add support for the Exynos990 usbdrd phy

2025-06-14T12:19:09+00:00

The Exynos990 usbdrd PHY is a combo PHY which supports USB SS, HS and
DisplayPort outputs. This commit adds support only for UTMI+ (USB HS).

phy: exynos5-usbdrd: support Exynos USBDRD 3.2 4nm controller

2025-05-14T10:43:38+00:00

Add support for the Exynos USB 3.2 DRD 4nm controller. It's used in
recent 4nm SoCs like Exynos2200 and Exynos2400.

This device consists of 3 underlying and independent phys: SEC link
control phy, Synopsys eUSB 2.0 and Synopsys USBDP/SS combophy. Unlike
older device designs, where the internal phy blocks were all IP of
Samsung, Synopsys phys are present. This means that the link controller
is now mapped differently to account for missing bits and registers.
The Synopsys phys also have separate register bases.

As there are non-SEC PHYs present now, it doesn't make much sense to
implement them in this driver. They are expected to be configured
by external drivers, so pass phandles to them. USBDRD3.2 link controller
set up is still required beforehand.

This commit adds the necessary changes for USB HS to work. USB SS and
DisplayPort are out of scope in this commit and will be introduced
in the future.

phy: exynos5-usbdrd: s/FIELD_PREP_CONST/FIELD_PREP where appropriate

2025-05-14T09:11:40+00:00

Commit 9b6662a0f715 ("phy: exynos5-usbdrd: use GENMASK and FIELD_PREP
for Exynos5 PHY registers") added FIELD_PREP_CONST() in many cases
where FIELD_PREP() would have been more appropriate. It also switched
existing uses of FIELD_PREP() to FIELD_PREP_CONST().

FIELD_PREP() is the preferred macro to use whenever possible while
FIELD_PREP_CONST() is meant to be used in constant initialisers.

Switch (back) to FIELD_PREP().

phy: exynos5-usbdrd: add exynos7870 USBDRD support

2025-04-10T13:42:17+00:00

Implement support for Exynos7870 USB DRD on top of the existing
exynos5-usbdrd driver.

Exynos7870 has a single USB 2.0 DRD PHY controller and no 3.0 PHYs. Thus,
it only supports the UTMI interface.

Moreover, the PMU register offset for enabling the PHY controller is
different for SoCs such as Exynos7870, where BIT(0) is for the 3.0 PHY and
BIT(1) is for the 2.0 PHY. The phy_isol function for Exynos7870 uses the
appropriate register offsets.
