Subject: coda 2040000.vpu: firmware request failed

Hi,

I'm observing firmware request failure with i.MX6Q board, This is with
latest linux-next (4.12) with firmware from, [1] and converted
v4l-coda960-imx6q.bin using [2].

Log:
------
coda 2040000.vpu: Direct firmware load for vpu_fw_imx6q.bin failed with error -2
coda 2040000.vpu: Direct firmware load for vpu/vpu_fw_imx6q.bin failed
with error -2
coda 2040000.vpu: Direct firmware load for v4l-coda960-imx6q.bin
failed with error -2
coda 2040000.vpu: firmware request failed

I've verified md4sum and VDDPU as well, hope these look OK.

# md5sum /lib/firmware/v4l-coda960-imx6q.bin
af4971a37c7a3a50c99f7dfd36104c63  /lib/firmware/v4l-coda960-imx6q.bin
# dmesg | grep regu | grep -i vddpu
[    0.061552] vddpu: supplied by regulator-dummy

Did I missed any, request for help?
