I looked at that header and it is very messy.

Can you make two new patches? The first aligns every nicely, e.g. this:

#define ZR36057_VFEHCR          0x000   /* Video Front End, Horizontal Configuration Register */
#define ZR36057_VFEHCR_HS_POL             BIT(30)
#define ZR36057_VFEHCR_H_START           10
#define ZR36057_VFEHCR_H_END            0
#define ZR36057_VFEHCR_HMASK            0x3ff

should become:

/* Video Front End, Horizontal Configuration Register */
#define ZR36057_VFEHCR			0x000
#define ZR36057_VFEHCR_HS_POL		BIT(30)
#define ZR36057_VFEHCR_H_START		10
#define ZR36057_VFEHCR_H_END		0
#define ZR36057_VFEHCR_HMASK		0x3ff

Same for all the other register blocks. Use tabs to do the alignment
instead of spaces, as is currently the case.

The second patch can replace the (0<<3) etc. to BIT(0).

That would be a nice cleanup of this rather messy header.

Thanks!
