2024-10-15usb: dwc3: invalidate dcache on buffer used in interrupt handlingNeil Armstrong
On Qualcomm systems, the setup buffer and even buffers are in a bad state at interrupt handling, so invalidate the dcache lines for the setup_buf and event buffer to make sure we read correct data written by the hardware. This fixes the following error: dwc3-generic-peripheral usb@a600000: UNKNOWN IRQ type -1 dwc3-generic-peripheral usb@a600000: UNKNOWN IRQ type 4673109 and invalid situation in dwc3_gadget_giveback() because setup_buf content is read at 0s and leads to fatal crash fixed by [1].

2024-10-15usb: dwc3: allocate setup_buf with dma_alloc_coherent()Neil Armstrong
Since setup_buf is also consumed by hardware DMA, aligns it's allocation like other hardware buffers by introduce setup_buf_addr populated by dma_alloc_coherent(), and use it to pass the physical address of the buffer to the hardware.

2024-06-19usb: dwc3: add newlines to dev_vdbg calls in ep0Caleb Connolly
For some reason none of these debug prints have newlines, resulting in a "fun" surprise when attempting to debug this driver. The other parts of the dwc3 driver have newlines, add them here too (and fix some minor nearby indent issues to make checkpatch happy).

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-04-14usb: dwc3: ensure consistent types for dwc3_flush_cachePhilipp Tomsich
The dwc3_flush_cache() call was declared and used inconsistently: * The declaration assumed 'int' for addresses (a potential issue when running in a LP64 memory model). * The invocation cast the address to 'long'. This change ensures that both the declaration and usage of this function consistently uses 'uintptr_t' for correct behaviour even when the allocated buffers (to be flushed) reside outside of the lower 32bits of memory.
