Please let me know if not. I did grep on drivers/video/ and could see lots of drivers use it (almost same definition). Ignore this comment as well, I could have recommended to move it to common file and do some cleanup, but not sure about background on this macro.

With respect to below reference from "The C Programming Language" from "Kernighan and Ritchie" I prefer to use "unsigned long", please let me know you views. " The intent is that short and long should provide different lengths of integers where practical; int will normally be the natural size for a particular machine. short is often 16 bits long, and int either 16 or 32 bits. Each compiler is free to choose appropriate sizes for its own hardware, subject only to the the restriction that shorts and ints are at least 16 bits, longs are at least 32 bits, and short is no longer than int, which is no longer than long." > >> > unsigned int palette_sz; > >> > unsigned int pxl_clk; > >> > int blank; > >> > @@ -546,6 +546,8 @@ static int lcd_cfg_frame_buffer(struct da8xx_fb_par *par, u32 width, u32 height, > >> > return 0; > >> > } > >> > > >> > + > >> > +#define CNVT_TOHW(val, width) ((((val)<<(width))+0x7FFF-(val))>>16) > >> > >> Did you run checkpatch.pl on this patch? > >> > > Prakash> Yes, checkpatch.pl did not complain anything on this line.
