NXP imx8MPlus integrates 2 indentical dwc3 3.30b IP with additional wakeup logic to support low power, this wakeup logic has a separated interrupt which can generate events with suspend clock(32K); due to SoC integration limitation, it only can support 32 bits DMA, so add dma-ranges property, changes for v5 - Remove "Items" of compatible in binding doc [1/4] - Add Krzysztof's R-b tag for patches [3-4/4]. changes for v4: - Use dma-ranges property to limit 32bits DMA, so don't need the new property "xhci-64bit-support-disable". - Fix binding doc to pass dt_binding_check dtbs_check. changes for v3: - Add dwc3 core related clocks into dwc3 core node, and glue layer driver only handle the clocks(hsio and suspend) for glue block, this is to match real HW. - Change to use property "xhci-64bit-support-disable" to disable 64bit DMA as imx8mp USB integration actully can't support it, so remove platform data in v2. - Some changes of imx8mp usb driver binding doc to address comments from Rob Changes for v2: - Drop the 2 patches for new property("snps,xhci-dis-64bit-support-quirk") introduction, as suggested, imply by SoC compatible string, this is done by introduce dwc3 core platform data and pass the xhci_plat_priv to xhci-plat for those xhci quirks, so a new patch added: [1/5] usb: dwc3: add platform data to dwc3 core device to pass data. this patch is based on Peter's one patch which is also in review: https://patchwork.kernel.org/patch/11640945/ - dts change, use the USB power function of TRL logic instead of a always-on regulator to control vbus on/off. - Some changes to address Peter's command on patch [2/5].
