Without this header, we get a compiler error in some configurations: .../dc/dcn20/dcn20_hwseq.c: In function 'dcn20_hwss_wait_for_blank_complete': .../dc/dcn20/dcn20_hwseq.c:1493:3: error: implicit declaration of function 'udelay' [-Werror=implicit-function-declaration] Note: the use of udelay itself may be problematic, as can occupy the CPU for 200ms in a busy-loop here.
