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.
Thanks & Regards,
Hans
