Hi,
We are using imx6Q custom platform for our development which is based on
sabresd platform.
We are using Linux 3.14.28_1.0.0-GA BSP for our development. But
initially we used Linux 3.10.53_1.0.0-GA BSP.
From Linux 3.10.53_1.0.0-GA BSP, we have referred the below Linux
kernel clock file.
~/linux-imx/arch/arm/mach-imx/clk-imx6q.c
We understood that the below function will set the LDB clock parent and
the default LDB clock parent is "pll2_pfd0_352m".
"init_ldb_clks"
But In Linux 3.14.28_1.0.0-GA BSP, we couldn't identify the parent clock
of LDB(LDB_DI0_SEL) clock. Please help us to understand
In our custom board, we are having LVDS0 800x480 display which is
working with Linux 3.10.53_1.0.0-GA BSP.
The issue we are facing is,
In Linux 3.14.28_1.0.0-GA BSP, we have modified the corresponding lvds0
timing parameters in device tree. Now we are not getting the LVDS0 display.
But if we keep the clock frequency as 65Mhz (as used in
~/linux-imx/arch/arm/boot/dts/imx6qdl-sabresd.dtsi) then we are able to
get the display.
Please note that, we have changed only clock frequency value and other
timing parameters are kept for 800x480 resolution.
We believe, the LDB clock's parent is the problem for our above issue.
Please help us to resolve the issue.
Thank You,
Regards,
Ansari
