Russell's v2 cover letter:
------------------ Hi,
This series adds dw-hdmi CEC support. This is done in four stages:
1. Add cec-notifier support 2. Fix up the clkdis register support, as this register contains a clock disable bit for the CEC module. 3. Add the driver. 4. Remove definitions that are not required from dw-hdmi.h
The CEC driver has been updated to use the register accessors in the main driver - it would be nice if it was possible to use the regmap support directly, but there's some knowledge private to the main driver that's required to correctly access the registers. (I don't understand why the register stride isn't part of regmap.)

v2 - fix selection of CEC_NOTIFIER in Kconfig ------------------
Changes in this v3:
- add missing cec_notifier_put to remove() - some checkpatch unsigned -> unsigned int changes - cec_transmit_done is replaced by the newer cec_transmit_attempt_done - added missing CEC_CAP_PASSTHROUGH
Regards,
Hans
