Total horizontal pixels = 1024 (x-res) + 80 (margin) + 48 (hsync) = 1152 Total vertical pixels = 600 (y-res) + 80 (margin) + 3 (vsync) = 683 Target pixel clock rate for refresh rate @60 Hz = 1152 * 683 * 60 = 47208960 Hz ~ 47.5 MHz Signed-off-by: Sachin Kamat Signed-off-by: Kukjin Kim --- arch/arm/boot/dts/exynos4412-origen.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/exynos4412-origen.dts b/arch/arm/boot/dts/exynos4412-origen.dts index d65984c440f6..95201559c3ad 100644 --- a/arch/arm/boot/dts/exynos4412-origen.dts +++ b/arch/arm/boot/dts/exynos4412-origen.dts @@ -159,7 +159,7 @@ display-timings { native-mode = <&timing0>; timing0: timing { - clock-frequency = <50000>; + clock-frequency = <47500000>; hactive = <1024>; vactive = <600>; hfront-porch = <64>;
