| * usb: dwc3: support clocks and resets for DWC3 coreMasahiro Yamada2018-05-161-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Historically, the clocks and resets are handled on the glue layer side instead of the DWC3 core. For simple cases, dwc3-of-simple.c takes care of arbitrary number of clocks and resets. The DT node structure typically looks like as follows: dwc3-glue { compatible = "foo,dwc3"; clocks = ...; resets = ...; ... dwc3 { compatible = "snps,dwc3"; ... }; } By supporting the clocks and the reset in the dwc3/core.c, it will be turned into a single node: dwc3 { compatible = "foo,dwc3", "snps,dwc3"; clocks = ...; resets = ...; ... } This commit adds the binding of clocks and resets specific to this IP. The number of clocks should generally be the same across SoCs, it is just some SoCs either tie clocks together or do not provide software control of some of the clocks. I took the clock names from the Synopsys datasheet: "ref" (ref_clk), "bus_early" (bus_clk_early), and "suspend" (suspend_clk). I found only one reset line in the datasheet, hence the reset-names property is omitted. Those clocks are required for new platforms. Enforcing the new binding breaks existing platforms since they specify clocks (and resets) in their glue layer node, but nothing in the core node. I listed such exceptional cases in the DT binding. The driver code has been relaxed to accept no clock. This change is based on the discussion [1]. I inserted reset_control_deassert() and clk_bulk_enable() before the first register access, i.e. dwc3_cache_hwparams().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | On Armada 7K/8K we need to explicitly enable the register clock. This clock is optional because not all the SoCs using this IP need it but at least for Armada 7K/8K it is actually mandatory. The change was done at xhci-plat level and not at a xhci-mvebu.c because, it is expected that other SoC would have this kind of constraint. The binding documentation is updating accordingly.

The most interesting parts are listed below: Synopsys has been adding better support for USB 3.1 to dwc3. The same series also sets g_mass_storage's max speed to SSP. Roger Quadros (TI) added support for dual-role using the OTG block available in some dwc3 implementations, this makes sure that AM437x can swap roles in runtime. We have a new SoC supported in dwc3 now - Amlogic Meson GX - thanks to the work of Martin Blumenstingl. We also have a ton of changes in dwc2 (51% of all changes, in fact). The most interesting part there is the support for Hibernation (a Synopsys PM feature). Apart from these, we have our regular set of non-critical fixes all over the place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DWC_usb31 periodic transfer at 48K+ bytes per interval may need modification to the TX/RX packet threshold to achieve optimal result. Add properties to make it configurable. By default, periodic ESS TX and RX threshold are not enabled. To enable TX or RX threshold (host mode only), both packet threshold count and max burst size properties must be set to a valid non-zero value 1-16.

Other than that, we have a set of changes on Renesas UDC to make the code a little easier to read and maintain while also better supporting extcon framework. The u_serial adaptation layer learned to use kfifo instead of cooking its own FIFO implementation. DWC3 learned to decode a few more USB requests on the trace output.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms (e.g. TI's DRA7 USB2 instance) have more trouble with the metastability workaround as it supports only a High-Speed PHY and the PHY can enter into an Erratic state [1] when the controller is set in SuperSpeed mode as part of the metastability workaround. This causes upto 2 seconds delay in enumeration on DRA7's USB2 instance in gadget mode. If these platforms can be better off without the workaround, provide a device tree property to suggest that so the workaround is avoided.

This is due to the fact that the MTK controller IMOD interval is 8 times as much as defined in xHCI spec. Instead of adding more quirk bits for additional platforms, this patch introduces the ability for vendors to set the IMOD_INTERVAL as is optimal for their platform. By using device_property_read_u32() on "imod-interval-ns", the IMOD INTERVAL can be specified in nano seconds. If no interval is specified, the default of 40,000ns (IMOD=160) will be used. No bounds checking has been implemented due to the fact that a vendor may have violated the spec and would need to specify a value outside of the max 8,000 IRQs/second limit specified in the xHCI spec.

| * | dt-bindings: usb: add #phy-cells to usb-nop-xceivRob Herring2017-11-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Consumers of usb-nop-xceiv use the phy binding, but #phy-cells is missing from the binding. This is probably because this binding predates the common phy binding. So add #phy-cells as a required property. This should not break any users as missing should be treated as 0 cells.

* | usb: usb251xb: Update usb251xb bindingsSerge Semin2017-11-011-14/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since hub usb2517 is going to be supported by the usb251xb driver, the bindings need to be properly updated. Particularly: - add "microchip,usb2517" and "microchip,usb2517i" compatible strings. - add "boolean" description to all the properties, which really accept a boolean value including a new one "led-{usb,speed}-mode". - move reset-gpios property to the optional section. It isn't defined as required in the code and shouldn't be required at all, since hardware may handle reset pins by itself. - add new led-{usb,speed}-mode mode property. USB2517 device supports two LED modes: USB mode and speed (default) indication mode. The last one can be switched on by this property. - add {bp,sp}-max-{total,removable}-current-microamp property measured in microamp. It hasn't been defined as property before. Since the limitation specified by these parameters is hardware specific it needs to be defined in dts.

With only 51 non-merge commits, this was one of the smallest pull requests from the Gadget tree. Most of the changes are in the mtu3 driver which added support for 36-bit DMA, support for USB 3.1 and support for dual-role (along with some non-critical fixes). The dwc2 driver got a few improvements to how we handle gadget state tracking and also added support for STM32F7xx devices. Other than that, we just some minor non-critical fixes and improvements all over the place.
| * | usb: renesas_usbhs: Add compatible string for r8a7743/5Biju Das2017-10-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for r8a7743/5 SoCs. The Renesas RZ/G1[ME] (R8A7743/5) usbhs is identical to the R-Car Gen2 family. No driver change is needed due to the fallback compatible value "renesas,rcar-gen2-usbhs". Adding the SoC-specific compatible values here has two purposes: 1. Document which SoCs have this hardware module, 2. Allow checkpatch to validate compatible values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XHCI specification 1.1 does not require xHCI-compliant controllers to always enable hardware USB2 LPM. However, the current xHCI driver always enable it when seeing HLC=1. This patch supports an option for users to control disabling USB2 Hardware LPM via DT/ACPI attribute. This option is needed in case user would like to disable this feature. For example, their xHCI controller has its USB2 HW LPM broken.
