Some USB controller drivers that depend on the xhci-plat driver specify this dependency using 'select' in Kconfig. This is not recommended for symbols that have other dependencies as it may lead to invalid configurations. Use 'depends on' to specify the dependency instead of 'select'. For DWC3 move the dependency from USB_DWC3 to USB_DWC3_HOST and USB_DWC3_DUAL_ROLE, to make the DWC3 core selectable for gadget-only mode when USB_XHCI_PLATFORM=n. Signed-off-by: Matthias Kaehlcke <mka@chromium.org> --- With this patch no Kconfig conflicts were observed with allmodconfig and in ~100 randconfig cycles.
