EDID is not loading from /lib/firmware
I wanted to load customized edid so I have added it's name as "drm_kms_helper.edid_firmware=edid/edid.bin" and I kept the edid under /lib/firmware/edid/.
But after booting the system, I cross checked from user space. It is not loading: cat /sys/module/drm_kms_helper/parameters/edid_firmware.
I've enabled the configurations DRM_LOAD_EDID_FIRMWARE=y.
Can anyone help me with this?

check what the kernel says at boot time with dmesg -H.
In my case with a similar config:
[ +0.000001] Kernel command line: (removed irrelevant options) drm_kms_helper.edid_firmware=edid/2560x1440.bin
[ +0.000180] [drm] drm_kms_firmware.edid_firmware is deprecated, please use drm.edid_firmware intead.
later...
[ +0.003042] [drm:drm_load_edid_firmware] *ERROR* Size of EDID firmware "edid/2560x1440.bin" is invalid (expected 0, got 127
Not sure what the cause is, but you should see some errors about your EDID file too.
