I checked with checkpatch script to code and give a some errors.
So, the code have to "udelay(20)".
udelay(20);
I read to Documentation/timers/timers-howto.txt and
this line incorrect, usleep_range need must be add defined U_DELAY and fixed.
udelay(U_DELAY, U_DELAY + 10);
finally:
$ checkpatch.pl drivers/staging/fbtft/fb_agm1264k-fl.c | grep total
total: 0 errors
