[5]? I don't think that's right. Look at the offsets.

I've been trying to get usbtty working on a DM355 (still isn't working...) and ran into a bug(?).
In drivers/usb/musb/davinci.h:
struct davinci_usb_regs { u32 version; u32 ctrlr; u32 reserved[0x20]; u32 intclrr; u32 intmskr; u32 intmsksetr; };
Shouldn't this be reserved[0x20/4] ?
Yes, this is a bug. Though the correct fix is,
- u32 reserved[0x20];
- u32 reserved[5];
Opps, there are actually 32 intermediate register each of 32 bits.
So the correct one is as Neal suggested.
- u32 reserved[0x20]; + u32 reserved[020/4];
