Subject: [PATCH v2 0/5] add NXP imx8mp usb support
Date: Mon, 6 Jul 2020 17:44:54 +0800 [thread overview]
Message-ID: <1594028699-1055-1-git-send-email-jun.li@nxp.com> (raw)
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, a few quriks required, instead of create new properties flags,
introduce platform data and pass it from glue layer to dwc3 core, those xhci
private data can further pass to xhci-plat.
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].
