Add missing OTGHS_SEL macro to STM32WBA clock header. This macro applies only to certain SoCs of STM32WBA6x series. Signed-off-by: Mathieu Choplain <[email protected]>
Add missing nodes for USB feature to STM32WBA6x DTSI. (Note: only WBA65 DTSI exists today, but USB is available in other SoCs of the series - this should be reworked later) Signed-off-by: Mathieu Choplain <[email protected]>
Add support for USB on STM32WBA6x series, along with a tiny rework of how the st,stm32u5-otghs-phy is handled to make the code more generic by actually consuming DT information. Signed-off-by: Mathieu Choplain <[email protected]>

There was a problem hiding this comment.
In this case, use of __HAL_RCC_SYSCFG_CLK_ENABLE() would enhance readability.

Add USB support for STM32WBA6 series:
nucleo_wba65riboardTested that
samples/subsys/usb/cdc_acmbuilds, runs and works as expected.(Also tested that it still works on
nucleo_u5a5zj_qto ensure no regression)Fixes #96705
