how to keep bootlogo from uboot to kernel for imx6solox BSP imx-yocto-L5.4.47

[dongin]

Dear everyone 

HW: imx6solox

BSP version : yocto / L5.4.47

we use LVDS panel

bootlogo appears in uboot, but screen turns off with kernel start during booting.

I already saw the patch through the link below.

Patch to support uboot logo keep from uboot to ker... - NXP Community

but, I can't find patch about L5.4.47. 

Please share patch.

Thank

We do not have that patch, and as the 6sxs is based on lcdif, not IPU， so no reference significance. During the kernel startup, keep the clock of lcdif.

Also, the setting of lcdif can be changed.

When the display driver is registered, the lcdif is not reset
