dt-bindings: usb: snps,dwc3: Fix "snps,hsphy_interface" type

2023-05-29T14:57:22Z

The "snps,hsphy_interface" is string, not u8. Fix the type.

dt-binding: cdns,usb3: Fix cdns,on-chip-buff-size type

2023-05-16T12:43:07Z

In cdns3-gadget.c, 'cdns,on-chip-buff-size' was read using device_property_read_u16(). It resulted in 0 if a 32bit value was used in dts. This commit fixes the dt binding doc to declare it as u16.

dt-bindings: usb: snps,dwc3: Add 'snps,parkmode-disable-hs-quirk' quirk

2023-04-20T09:18:12Z

Add a new 'snps,parkmode-disable-hs-quirk' DT quirk to dwc3 core for disable the high-speed parkmode. For some USB wifi devices, if enable this feature it will reduce the performance. Therefore, add an option for disabling HS park mode by device-tree. In Synopsys's dwc3 data book: In a few high speed devices when an IN request is sent within 900ns of the ACK of the previous packet, these devices send a NAK. When connected to these devices, if required, the software can disable the park mode if you see performance drop in your system. When park mode is disabled, pipelining of multiple packet is disabled and instead one packet at a time is requested by the scheduler. This allows up to 12 NAKs in a micro-frame and improves performance of these slow devices.

dt-bindings: usb: ci-hdrc-usb2: allow multiple PHYs

2023-04-20T09:17:17Z

Qualcomm MSM8974 comes with USB HS phy in two variants, although final DTS chooses only one. Allow such combination in the ChipIdea USB2 bindings and also disallow any other properties in the ulpi node.

dt-bindings: usb: dwc2: add utmi optional clock

2023-04-20T08:17:06Z

utmi clock is typically provided by PHY output. Add this optional clock, as the core could use other clocks depending on the SoC where it's used. This is needed on stm32mp15, when using the integrated full-speed PHY.

dt-bindings: Add missing (unevaluated|additional)Properties on child node schemas

2023-04-05T20:38:38Z

Just as unevaluatedProperties or additionalProperties are required at the top level of schemas, they should (and will) also be required for child node schemas. That ensures only documented properties are present. Add unevaluatedProperties or additionalProperties as appropriate, and then add any missing properties flagged by the addition.

dt-bindings: usb: ti,keystone-dwc3: drop assigned-clocks

2023-04-05T17:17:12Z

The meta schema from DT schema already defines assigned-clocks, so there is no need for device schema to mention it at all. There are also no benefits of having it here.
