Are these all aligned in the actual file?

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!

	Hans

Okay Sir, will do this.

Sir may I know how to write (2<<3) in BIT() form? Like I am still
learning and not sure how to convert this. Should it be BIT(2)? But this
is only possible for (1<<nr), PLease help me out. 

Thanks.

I think that you are correct.  BIT is not usable her.

The << notation is kept for that. So this would be kept as-is:

#define ZR36057_VFESPFR_YUV422          (0 << 3)
#define ZR36057_VFESPFR_RGB888          (1 << 3)
#define ZR36057_VFESPFR_RGB565          (2 << 3)
#define ZR36057_VFESPFR_RGB555          (3 << 3)

BIT() is only used for single bits.

Then I guess only one new patch would be needed for proper alignment, am
i right? I have to rename it as v2 or should send as a completely new
patch?
