Hi
I test this code.
error =3D clk_set_freq(clk_vid,=C2=A0222000000, CLK_SET_ROUND_DOWN);
error =3D clk_get_freq(clk_vid, &lcd_fout);
device_printf(sc->dev, "MORI MORI freq=C2=A0CLK_PLL_VIDEO0 %llu\n", lcd_fou=
t);
Result is this.
fb0: MORI MORI freq=C2=A0CLK_PLL_VIDEO0=C2=A0240000000
clkng is not work=C2=A0correctly.
