This patchset aims to support flags for e.g. over-current active low or port permanantly attached which are provided in the USB3 glue layer. In v4 the patchset depends on Lucas' i.MX8MP power-domains patchset [2]. Because of that the 'phy' clock usage can be dropped, as now power domains take care of the clocks. Due to powering up/down the glue layer settings will have to be reapplied during resume. Changes in v5: * Added Reviewed-by: Li Jun to PATCH 1 & 4 * Added Reviewed-by: Rob Herring to PATCH 2 * Added comment in PATCH 3 why reprogramming is necessary in resume Changes in v4: * Depends on Lucas' i.MX8MP power-domains patchset * removed 'phy' clock usage from dwc3-imx8mp.c * Reapply glue layer settings upon resume Changes in v3: * Rename existing member for clarity * Moved feature implementation from phy-fsl-imx8mq-usb.c to dwc3-imx8mp.c [1] https://patchwork.kernel.org/project/linux-arm-kernel/cover/20220126141340.234125-1-alexander.stein@ew.tq-group.com/ [2] https://patchwork.kernel.org/project/linux-arm-kernel/cover/20220119134027.2931945-1-l.stach@pengutronix.de/ Alexander Stein (4): usb: dwc3: imx8mp: rename iomem base pointer dt-bindings: usb: dwc3-imx8mp: Add imx8mp specific flags usb: dwc3: imx8mp: Add support for setting SOC specific flags arm64: dts: imx8mp: Add memory for USB3 glue layer to usb3 nodes .../bindings/usb/fsl,imx8mp-dwc3.yaml | 31 +++++++- arch/arm64/boot/dts/freescale/imx8mp.dtsi | 6 +- drivers/usb/dwc3/dwc3-imx8mp.c | 77 +++++++++++++++++-- 3 files changed, 101 insertions(+), 13 deletions(-)
