On a board design based on the LS1012A Freedom board, we added a USB 2.0 connection (in addition to the USB 3.0 included on the Freedom board).
I have run into a challenge building the Linux kernel driver to support the ULPI connection. With CONFIG_USB_EHCI_FSL defined, the code will not build because CONFIG_PM is defined and causes drivers/usb/host/ehci-fsl.c to try and pull in asm/fsl_pm.h which is not provided for qoriq (only for powerpc!). CONFIG_PM is: · not in arch/arm64/configs/defconfig (which I am pretty sure is used as the “base” for make defconfig in meta-freescale/recipes-kernel/linux/linux-qoriq_4.14.bb) · nor is it in arch/arm64/configs/lsdk.config (which I am pretty sure is the DELTA_KERNEL_DEFCONFIG used in meta-freescale/recipes-kernel/linux/linux-qoriq_4.14.bb) · nor can I find it in any Kconfig in the linux-qoriq source tree Even so, it ends up in the .config file created when I build the linux-qoriq recipe. Can anyone point out what I am missing that results in CONFIG_PM getting defined? I have put in a workaround to #undef CONFIG_PM in ehci-fsl.c and am now able to get the second USB 2.0 bus, but I would like to find the "root source" to patch if I can. Thanks! -- .Tim
