This happens when PPC_EP88XC is set, which selects CPM1 & CPM. When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE being set. When USB_FSL_QE is set, QE_USB deafults to y, which causes build errors when QUICC_ENGINE is not set. Making QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y. Fixes these build errors: drivers/soc/fsl/qe/usb.o: in function `qe_usb_clock_set': usb.c:(.text+0x1e): undefined reference to `qe_immr' powerpc-linux-ld: usb.c:(.text+0x2a): undefined reference to `qe_immr' powerpc-linux-ld: usb.c:(.text+0xbc): undefined reference to `qe_setbrg' powerpc-linux-ld: usb.c:(.text+0xca): undefined reference to `cmxgcr_lock' powerpc-linux-ld: usb.c:(.text+0xce): undefined reference to `cmxgcr_lock' Fixes: 5e41486c408e ("powerpc/QE: add support for QE USB clocks routing") Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Link: https://lore.kernel.org/all/202301101500.pillNv6R-lkp@xxxxxxxxx/ Suggested-by: Michael Ellerman <mpe@xxxxxxxxxxxxxx> Cc: Christophe Leroy <christophe.leroy@xxxxxxxxxx> Cc: Leo Li <leoyang.li@xxxxxxx> Cc: Masahiro Yamada <masahiroy@xxxxxxxxxx> Cc: Nicolas Schier <nicolas@xxxxxxxxx> Cc: Qiang Zhao <qiang.zhao@xxxxxxx> Cc: linuxppc-dev <linuxppc-dev@xxxxxxxxxxxxxxxx> Cc: linux-arm-kernel@xxxxxxxxxxxxxxxxxxx Cc: Kumar Gala <galak@xxxxxxxxxxxxxxxxxxx> Acked-by: Nicolas Schier <nicolas@xxxxxxxx> Signed-off-by: Li Yang <leoyang.li@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> diff --git a/drivers/soc/fsl/qe/Kconfig b/drivers/soc/fsl/qe/Kconfig index fabba17e9d65b..7ec158e2acf91 100644 --- a/drivers/soc/fsl/qe/Kconfig +++ b/drivers/soc/fsl/qe/Kconfig @@ -37,6 +37,7 @@ config QE_TDM config QE_USB bool + depends on QUICC_ENGINE default y if USB_FSL_QE help QE USB Controller support
