Subject: [media] coda: add support for firmware files named as distributed by NXP Author: Philipp Zabel <[email protected]> Date: Fri Feb 19 07:18:57 2016 -0200 Try loading the firmware from firmware files named vpu_fw_imx*.bin, as they are originally distributed by NXP. Fall back to v4l-coda*-imx6*.bin.
