Now that the musb sunxi glue driver is completely device model / device tree driven, we should use the base address from the device tree, instead of hard-coding it in the source code.
Fixes: 3a61b080acee ("musb: sunxi: switch to the device model") Signed-off-by: Chen-Yu Tsai wens@csie.org --- Changes since v1:
- Check return value dev_read_addr_ptr()
IMHO, having NULL represent an error for dev_read_addr_ptr() doesn't work so well as in the kernel, because U-boot doesn't acually map addresses. So NULL (or 0x0) is in fact a valid address. Something like ~0x0 might work better, but that's a whole other changeset.
