I applied your patch to rockchip/next on an FriendlyElec CM3588 device with arm-

Sadly I could not get it to work at all.

After connection to a HDMI source I get the following error with all devices and 
resolutions I tested
# dmesg
snps_hdmirx fdee0000.hdmi_receiver: hdmirx_controller_init wait timer base lock 
failed
snps_hdmirx fdee0000.hdmi_receiver: hdmirx_phy_register_write wait cr write done 
failed (repeating multiple times)

Sounds like interrupt may be not working for you. Interrupt won't work
using downstream version of AT-F, though I assume you're using vanilla
version of the AT-F. Could you please show output of `cat
/proc/interrupts | grep rk_hdmirx` after plugging the HDMI cable.
