LVDS pixel clock setting update for KK4.4.3

[torus1000]

Hi,

My re-built KK4.4.3 image works fine except LVDS port which replaced panel attached.

I followed described instructions and I tried to change LVDS clock from 38MHz to 30MHz but couldn't change yet.

      (1) arch/arm/mach-imx/clk-imx6q.c
           clk_set_parent(clk[ldb_di0_sel], clk[pll5_video_div]);
      (2) drivers/video/mxc/ldb.c supposed to move arch/arm/boot/dts/imx6qdl-sabresd.dtsi
           clock-frequency = <30000000>;

Can anyone help me to correct my LVDS clock setting? Which files do I need to fix?

Thanks.

I found the comment how to change the clock source in 154 line of kernel_imx/arch/arm/mach-imx/clk-imx6q.c.

I added parameter as following then it worked.

u-boot=> setenv mmcargs... ldb_di_clk_sel=pll5_video_div
u-boot=> boot
