Merge tag 'phy-for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/phy/linux-phy
Pull phy updates from Vinod Koul:
"As usual featuring couple of new driver and bunch of new device
support and some driver changes to Freescale, rockchip driver along
with couple of yaml binding conversions.
New Support:
- Qualcomm IPQ5424 qusb2 support, IPQ5018 uniphy-pcie driver
- Rockchip usb2 support for RK3562, RK3036 usb2 phy support
- Samsung exynos2200 eusb2 phy support and driver refactoring for
this support, exynos7870 USBDRD support
- Mediatek MT7988 xs-phy support
- Broadcom BCM74110 usb phy support
- Renesas RZ/V2H(P) usb2 phy support
Updates:
- Freescale phy rate claculation updates, i.MX95 tuning support
- Better error handling for amlogic pcie phy
- Rockchip color depth configuration and management support
- Yaml binding conversion for RK3399 Type-C and PCIe Phy"
