writel(CTRL_DOTCLK_MODE, host->base + CTRL + SET)

For this we already have __mxs_setl.

NACK.

This will indeed not be caught by the compiler.

And while I like the shorter macros better as well, an MXSFB_ prefix
should be added IMO. Macros like CTRL and TIMING are not too well
protected.

+1 for a prefix, be it MXSFB_ or LCDIF_, will change this.

Otherwise can we please stop about arguing about register defines? It's
too much a matter of taste and there is no perfect way to solve this.

Guo Shawn mmc driver's patch is good example to use mx23/mx28 register macro.
