usb: common: Use helper function for_each_node_with_property()

2024-08-13T08:37:21+00:00

for_each_node_with_property() can iterate through the device_node with a given property name, and we don't need to find the device_node in the while loop. Since of_device_is_available() will return false if the "controller" is NULL and break the while loop, there is no functional change with such conversion.

usb: Explicitly include correct DT includes

2023-07-25T16:20:02+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

usb: common: move function's kerneldoc next to its definition

Following a general rule, add the kerneldoc for a function next to it's definition, but not next to its declaration in a header file.

usb: common: Parse for USB SSP genXxY

2021-02-06T13:21:21+00:00

The USB "maximum-speed" property can now take the SSP signaling rate generation and lane count with these new strings: "super-speed-plus-gen2x2" "super-speed-plus-gen2x1" "super-speed-plus-gen1x2" Introduce usb_get_maximum_ssp_rate() to parse for the corresponding usb_ssp_rate enum. The original usb_get_maximum_speed() will return USB_SPEED_SUPER_PLUS if it matches one of these new strings.

USB: move usb debugfs directory creation to the usb common core

2019-06-06T06:59:19+00:00

The USB gadget subsystem wants to use the USB debugfs root directory, so move it to the common "core" USB code so that it is properly initialized and removed as needed. In order to properly do this, we need to load the common code before the usb core code, when everything is linked into the kernel, so reorder the link order of the code. Also as the usb common code has the possibility of the led trigger logic to be merged into it, handle the build option properly by only having one module init/exit function and have the common code initialize the led trigger if needed.
