* media: s5p-cec: add NACK detection supportHans Verkuil2017-09-231-1/+2
| | | | | | | | | | | | | | | | | | | The s5p-cec driver returned CEC_TX_STATUS_ERROR for the NACK condition. Some digging into the datasheet uncovered the S5P_CEC_TX_STAT1 register where bit 0 indicates if the transmit was nacked or not. Use this to return the correct CEC_TX_STATUS_NACK status to userspace. This was the only driver that couldn't tell a NACK from another error, and that was very unusual. And a potential problem for applications as well. Tested with my Odroid-U3.

* [media] s5p-cec: add cec-notifier support, move out of stagingHans Verkuil2017-04-101-0/+208
By using the CEC notifier framework there is no longer any reason to manually set the physical address. This was the one blocking issue that prevented this driver from going out of staging, so do this move as well. Update the bindings documenting the new hdmi phandle and update exynos4.dtsi accordingly. Tested with my Odroid U3.
