2025-10-28usb: ulpi: Incorrect operator usedAndrew Goodbody
Combining two bits into a mask to be used so that the same write code can be used to set or reset bits in a register clearly needs to use the binary 'or' operator, not the binary 'and'. Fix it. This issue was found by Smatch. Signed-off-by: Andrew Goodbody <[email protected]>
2025-05-25usb: ulpi: Clean up how we enable supportTom Rini
The way we enable ULPI support today isn't something that should work. The "optional" keyword in a choice statement is not a documented feature. To make this work in a supported way, make USB_ULPI something we ask about if USB_HOST is set. Next, we move the choice of what viewer to use to be after the framework portion and to depend on that. We then borrow a few words from the top-level README to make the help text here clearer. Finally we make the Qualcomm driver select ULPI as it's required and we make the tegra driver not duplicate a check that Kconfig now handles for us. Signed-off-by: Tom Rini <[email protected]>

2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

2023-01-20global: Finish CONFIG -> CFG migrationTom Rini
At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

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 <[email protected]>
2018-02-05usb: ulpi: kconfig: Remove meaningless choice defaultUlf Magnusson
'default' on a choice refers to the symbol selected by default, not to the choice mode, so 'default n' is meaningless. No functional changes. Optional choices implicitly default to n mode (and there is no way to make them default to another mode). Discovered in Kconfiglib (https://github.com/ulfalizer/Kconfiglib), which prints the following warning: warning: the default selection n (undefined) of <choice> (defined at drivers/usb/ulpi/Kconfig:3) is not contained in the choice I've added a corresponding warning to the C tools too, which is currently in linux-next: https://patchwork.kernel.org/patch/9983667/ Signed-off-by: Ulf Magnusson <[email protected]>
2016-04-01usb: ulpi: Fix compile warning in read/write on 64-bit machines.Mateusz Kulikowski
ulpi_read and ulpi_write are used to read/write registers via ULPI bus. Code generates compilation warnings on 64-bit machines where pointer is cast to u32. This patch drops all but last 8 bits of register address. It is possible, because addresses on ULPI bus are 6- or 8-bit. It is not possible (according to ULPI 1.1 spec) to have more than 8-bit addressing. This patch should not cause regressions as all calls to ulpi_read/write use either structure pointer (@ address 0) or integer offsets cast to pointer - addresses requested are way below 8-bit range.

2013-07-02usb: omap: ulpi: fix ulpi transceiver accessMichael Trimarchi
This patch fix the omap access to the transceiver configuration registers using the ulpi bus. As reported by the documentation the bit31 is used only to check if the transaction is done or still running and the reading and writing operation have different offset and have different values. What we need to do at the end of a transaction is leave the bus in done state. Anyway an error using the ulpi omap register is not recoverable so any error give out the usage of this interface. Tested on a custom OMAP5430 board with a TUSB1210 ULPI PHY on USBB1.

2012-02-12usb: ulpi: Add omap-ulpi-view port supportGovindraj.R
Based on discussion from this thread [1]. Adding omap-view port that helps us in using the generic ulpi framework for any ulpi phy ops using the INSNREG05_ULPI viewport reg available on omap platform. Currently ehci ports are available on omap3/4 platforms so enable the same for beagle and panda, patch is tested on the same boards. Thanks to Igor Grinberg <[email protected]> for reviewing the omap-ehci patches and suggesting this approach.
