2023-07-10arm64: zynqmp: Fix dwc3 usb interrupt descriptionMichal Simek1-4/+4
Based on DT binding dwc_usb3 is single entry without anything else. That's why combination dwc3_usb3, otg is not allowed. That's why split it to host and peripheral pair which both points to the same IRQ. DWC3 code is reading these two properties first before generic dwc_usb3.

2023-07-10arm64: zynqmp: Add memory reserved node for k26 Kria SOM boardSharath Kumar Dasari1-0/+11
PMUFW (Power Management Unit firmware) requires top 1MB of the lower DDR memory reserved for its operation, this is missing in k26 SM static dts file. Bootloader or kernel shouldn't access this location.

2023-07-10arm64: zynqmp: Assign TSU clock frequency for GEMsHarini Katakam3-0/+6
Allow changing TSU clock for all GEMs. Kria SOM is using this functionality that's why set TSU clock frequency as 250MHz (minimum when running at 1G) to allow PTP functionality.
