Subject: musb: sunxi: Add fifo config
X-Git-Tag: v2018.07-rc1~8^2~32
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=97202dd6ecd3465349264eba6fc124ceac22675a;p=oweals%2Fu-boot.git

musb: sunxi: Add fifo config

Unlike other Allwinner SOC's H3/H5/V3s OTG support 4 endpoints
with relevant fifo configs, rest all have 5 endpoints.
So add the fifo configs and defer them based on driver_data.
