d4f6b987f3 dt-bindings: usb: samsung,exynos-dwc3: allow unit address in DTS 
The Samsung Exynos SoC USB 3.0 DWC3 Controller is a simple wrapper of
actual DWC3 Controller device node.  It handles necessary Samsung
Exynos-specific resources (regulators, clocks), but does not have its
own MMIO address space.

However neither simple-bus bindings nor dtc W=1 accept device nodes in
soc@ node which do not have unit address.

ff826648e1 USB: MAX3421: Handle USB NAK correctly 
A USB peripheral can respond with a NAK if it is not yet ready to
send/receive data. In this case, the transaction should be retried. The
MAX3421 driver did do this, and switched to a different type of retry
after a number of 'fast' retries. On at least some USB flash devices,
this second type of retry never succeeds. This patch changes the
behaviour so that 'fast' retries continue.

015d44c2b7 media: uvcvideo: Add GUID for BGRA/X 8:8:8:8 
The Cypress EZUSB FX3 UVC example can be configured to report pixel
format "e436eb7e-524f-11ce-9f53-0020af0ba770". This is its GUID for
BGRA/X 8:8:8:8.

The UVC 1.5 spec [1] only defines GUIDs for YUY2, NV12, M420 and I420.
This seems to be an extension documented in the Microsoft Windows Media
Format SDK[2]. This Media Format SDK defines this GUID as corresponding
to `MEDIASUBTYPE_RGB32`, which is confirmed by [4] as `MEDIASUBTYPE_ARGB32`
has different GUID.

Note that in my case, the FX3 UVC can output either channel order,
BGR or RGB or any other mix for that matter. Since Linux commit
1b8dc32286 ("[media] uvcvideo: Add GUID for BGR 8:8:8")
defined a GUID for `MEDIASUBTYPE_RGB24` channel order as BGR, keep
this change consistent and define `MEDIASUBTYPE_RGB32` as BGR as well.
Document [3] also indicates the channel order is BGR.

76ea4926dc dt-bindings: usb: Convert OMAP OHCI/EHCI bindings to schema 
The OMAP OHCI and EHCI USB host bindings follow the generic binding, so
add the compatibles and remove the old txt binding docs.

The examples in omap-usb-host.txt don't match actual users, so update
them dropping the fallback compatible.

4aa466190a dt-bindings: usb: Convert multiple "usb-ohci" bindings to DT schema 
"usb-ohci" is another "generic" OHCI controller compatible string used by
several platforms. Add it to the generic-ohci.yaml schema and remove all
the old binding docs.

Marvell pxa-usb.txt has "usb-ohci" in the example, but actual users don't,
so drop it.

5442e79120 dt-bindings: usb: rockchip,dwc3: Move RK3399 to its own schema 
The rockchip,dwc3.yaml schema defines a single DWC3 node, but the RK3399
uses the discouraged parent wrapper node and child 'generic' DWC3 node.
The intent was to modify the RK3399 DTs to use a single node, but the DT
changes were rejected for ABI reasons. However, the schema was accepted
as-is.

To fix this, we need to move the RK3399 binding to its own schema file.
The RK3328 and RK3568 bindings are correct and use a single node.

353a17ec62 dt-bindings: usb: snps,dwc3: Allow power-domains property 
The Rockchip RK3399 DWC3 node has 'power-domains' property which isn't
allowed by the schema:

usb@fe900000: Unevaluated properties are not allowed ('power-domains' was unexpected)

Allow DWC3 nodes to have a power-domains entry. We could instead move
the power-domains property to the parent wrapper node, but the could be
an ABI break (Linux shouldn't care). Also, we don't want to encourage
the pattern of wrapper nodes just to define resources such as clocks,
resets, power-domains, etc. when not necessary.

A design found in various Qualcomm-based boards is to use a USB switch,
controlled through a pair of GPIO lines to connect, disconnect and
switch the orientation of the SBU lines in USB Type-C applications.

This introduces a generic driver, which implements the typec_switch and
typec_mux interfaces to perform these operations.
