Hi! I am developing a system in which the video support is made through two ARM' HDLCD Controller and two TDA998x HDMI PHYs. When I try to load ARM' HDLCD driver (hdlcd), it fails when it tries to bind with the drm subsystem: root@genericarmv8:~# modprobe hdlcd [drm] found ARM HDLCD version r0p0 hdlcd 7ff50000.hdlcd: master bind failed: -517 [drm] found ARM HDLCD version r0p0 hdlcd 7ff60000.hdlcd: master bind failed: -517 The kernel has the controllers mapped in the I2C bus: root@genericarmv8:/sys/bus/i2c/drivers/tda998x# ls -l total 0 lrwxrwxrwx 1 root root 0 Nov 6 00:44 0-0070 -> ../../../../devices/platform/7ffa0000.i2c/i2c-0/0-0070 lrwxrwxrwx 1 root root 0 Nov 6 00:44 0-0071 -> ../../../../devices/platform/7ffa0000.i2c/i2c-0/0-0071 --w------- 1 root root 4096 Nov 6 00:44 bind --w------- 1 root root 4096 Nov 6 00:44 uevent --w------- 1 root root 4096 Nov 6 00:44 unbind I know that this driver is not supported in the mainline yet, but did anyone face a similar problem? Thank you very much for your time!
