This patch series replaces patches 1-3 of:
https://www.spinics.net/lists/linux-media/msg141216.html
Patches 4 & 5 of that series remain as-is and are omap4 bug fixes.
This patch series can be applied to the media subsystem since it has no drm changes.
Changes since the previous patch series are:
- Added a new patch improving the documentation of the cec_transmit_done function to hopefully avoid the omap4 bug in the future.
- Add a new patch that fixes a bug in the Signal Free Time calculation of the CEC framework. This affects hardware that relies on the framework for this value. This bug could basically cause a 'denial of service' situation on the CEC bus. Found with the cec-compliance adapter test, which does really nasty things :-)
- Improve cec-gpio to fixup the Signal Free Time if a transmit is delayed because a new message was received first (thus requiring a lower SFT).
All patches are meant for 4.20, and patches 2-5 will get a CC to stable for 4.18 and up.
The adv patches could go back to older kernels, but it's not very important.
I'll post a pull request for this series soon.
Regards,
Hans
