[PATCH 2/2] drm/arm/hdlcd: Allow a bit of clock tolerance

2019-05-17 Thread Robin Murphy
On the Arm Juno platform, the HDLCD pixel clock is constrained to 250KHz resolution in order to avoid the tiny System Control Processor spending aeons trying to calculate exact PLL coefficients. This means that modes like my oddball 1600x1200 with 130.89MHz clock get rejected since the rate cannot
