The Arm MPS3 FPGA prototyping board [0] have an isp1763 [1] as USB controller. There is already support for the isp1760 and isp1761 in tree, this series extend the support also for the isp1763. Move register access using regmap, remove some platform data and code, refactor the mempool, use dr_mode to align to existing bindings, then add the support for isp1763 host mode, add bindings files that did not existed and at the end add also support for peripheral mode for isp1763. @Laurent and @Sebastian, I add both of you in the bindings files as maintainers (it is a mandatory field)since you were the ones which contributed with the initial code and peripheral code, let me know if you are ok with it. If yes I may send a follow up to add also entries in MAINTAINERS file that it is also missing. v1 [2] -> v2: kernel test robot: - add two patches (1/9 and 3/9) to fix dozens of pre-existing sparse warnings so that this series does not introduce new ones. No sparse warning left. - fix duplication of regmap fields Laurent: - move initializers from .h to .c - change interrupt registers setup from field to one shot register setting (did not change hcd hw mode init because I think it did not make the difference and even avoid artifact around setting twice the register) Rob test bot: - fix suffix at compatible string to clean up warning in bindings Cheers, Rui [0]: https://developer.arm.com/tools-and-software/development-boards/fpga-prototyping-boards/mps3 [1]: https://media.digikey.com/pdf/Data%20Sheets/ST%20Ericsson%20PDFs/ISP1763A.pdf [2]: https://lore.kernel.org/linux-devicetree/20210504101910.18619-1-rui.silva@xxxxxxxxxx/ Rui Miguel Silva (9): usb: isp1760: fix strict typechecking usb: isp1760: move to regmap for register access usb: isp1760: use relaxed primitives usb: isp1760: remove platform data struct and code usb: isp1760: hcd: refactor mempool config and setup usb: isp1760: use dr_mode binding usb: isp1760: add support for isp1763 dt-bindings: usb: nxp,isp1760: add bindings usb: isp1763: add peripheral mode .../devicetree/bindings/usb/nxp,isp1760.yaml | 59 + arch/arm/boot/dts/arm-realview-eb.dtsi | 2 +- arch/arm/boot/dts/arm-realview-pb1176.dts | 2 +- arch/arm/boot/dts/arm-realview-pb11mp.dts | 2 +- arch/arm/boot/dts/arm-realview-pbx.dtsi | 2 +- arch/arm/boot/dts/vexpress-v2m-rs1.dtsi | 2 +- arch/arm/boot/dts/vexpress-v2m.dtsi | 2 +- drivers/usb/isp1760/Kconfig | 4 +- drivers/usb/isp1760/isp1760-core.c | 513 ++++++++- drivers/usb/isp1760/isp1760-core.h | 44 +- drivers/usb/isp1760/isp1760-hcd.c | 1021 ++++++++++++----- drivers/usb/isp1760/isp1760-hcd.h | 57 +- drivers/usb/isp1760/isp1760-if.c | 41 +- drivers/usb/isp1760/isp1760-regs.h | 435 ++++--- drivers/usb/isp1760/isp1760-udc.c | 250 ++-- drivers/usb/isp1760/isp1760-udc.h | 13 +- include/linux/usb/isp1760.h | 19 - 17 files changed, 1758 insertions(+), 710 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/nxp,isp1760.yaml delete mode 100644 include/linux/usb/isp1760.h -- 2.31.1
