below is my dts
panel {
compatible = "ti,tilcdc,panel";
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&lcd_pins_s0>;
panel-info {
ac-bias = <255>;
ac-bias-intrpt = <0>;
dma-burst-sz = <16>;
bpp = <32>;
fdd = <0x80>;
sync-edge = <0>;
sync-ctrl = <1>;
raster-order = <0>;
fifo-th = <0>;
};
display-timings {
native-mode = <&timing0>;
timing0: lcd {
clock-frequency = <70000000>;
hactive = <1920>;
vactive = <1080>;
hfront-porch = <48>;
hback-porch = <80>;
hsync-len = <32>;
vback-porch = <24>;
vfront-porch = <3>;
vsync-len = <5>;
hsync-active = <1>;
vsync-active = <0>;
de-active = <1>;
pixelclk-active = <1>;
};
};
};
above setting give us 1920x1080 with 30.3 Frame rate.
we want 1920x1080 with 60 Hz Frame rate
i understand The frame rate is derived from the pixel clock frequency, panel size, and H/V back/front porches.
can some tell what is exatct formula to calculate framerate
