Hi, sunxi musb (otg) support should land in 4.3, this has made me take a look at the Fedora ARM kernel config, esp. since the sunxi musb code only works with CONFIG_MUSB_PIO_ONLY=y
One thing stands out here, config-armv7 has: CONFIG_USB_TI_CPPI41_DMA=y Where as config-armv7-generic has: CONFIG_MUSB_PIO_ONLY=y And these 2 are mutually exclusive ... I started investigating this after seening a /boot/config-.... which had "# CONFIG_MUSB_PIO_ONLY is not set", but I cannot find the kernel with that anymore, so this may be my memory playing tricks with me. Either way I believe that it would be good to remove the CONFIG_USB_TI_CPPI41_DMA=y From config-armv7, because we do not want that. While on the subject of ARM kernel config, can we please have: CONFIG_TOUCHSCREEN_CHIPONE_ICN8318=m CONFIG_INPUT_AXP20X_PEK=m Added to one of the armv7 config files (not sure which one is appropriate), this enables support for a touchscreen found on some tablets we support, resp. for getting input events for power button presses on pretty much all Allwinner devices. And last I wonder what the policy is for having things as module vs builtin, e.g. on x86 usb controllers and the most common storage controllers are builtin to speed boot-up, sunxi certainly could benefit from building in CONFIG_MMC_SUNXI and CONFIG_MMC_BLOCK, but as said I've no idea what the policy is here.
