2025-03-11arm64: dts: freescale: imx8mp-skov: operate SoC in nominal modeAhmad Fatoum
To reduce heat generation, the Skov i.MX8MP boards should run in nominal drive mode with a VDD_SOC voltage of 850 mV.

The comment in the DT mentions that "currently it is not possible to let display clocks configure automatically, so we need to set them manually". Since commit ff06ea04e4cf ("clk: imx: clk-imx8mp: Allow media_disp pixel clock reconfigure parent rate"), this is no longer the case.

The imx8mp-nominal.dtsi is meant to be included into boards that want to override the default overdrive clock settings with settings suitable for running in nominal drive mode at its lower required voltage. Specifying fsl,operating-mode = "nominal" informs drivers of this fact, so they can sanity check runtime clock reconfiguration to observe the limits imposed by nominal mode.

2025-03-11arm64: dts: imx8mp: Add optional nominal drive mode DTSIAhmad Fatoum
Unlike the i.MX8MM and i.MX8MN SoCs added earlier, the device tree for the i.MX8MP configures some clocks at frequencies that are only validated for overdrive mode, i.e. when VDD_SOC is 950 mV. Boards may want to run their SoC at the lower voltage of 850 mV though to reduce heat generation and power usage. For this to work, clock rates need to adhere to the limits of the nominal drive mode. Add an optional DTSI file which can be included by various boards to run in this mode.

A lot of other clocks on the i.MX8MP, including the DRAM set up by the bootloader are already running at overdrive clock rates. While this is a deviation from the configuration of other i.MX8M* family SoCs, overdrive is the default for most i.MX8MP boards and only some special purpose boards will choose to run the SoC at nominal drive rates. Up the GPU and NPU clock rates to their overdrive level to be consistent with other clocks set up in the dtsi.

2025-03-11arm64: dts: freescale: ten64: add usb hub definitionMathew McBride
A device tree binding for the Microchip USB5744 hub controller was added in commit 02be19e914b8 ("dt-bindings: usb: Add support for Microchip usb5744 hub controller"). U-Boot will consume this binding in order to perform the necessary actions to enable the USB hub ports over I2C. (We previously used our own out-of-tree driver for this task) The Ten64 board does not have any switchable supplies for the voltage rails utilized by the USB5744, so a pair of dummy supplies have been added to facilitate operation with U-Boot's hub driver.
