2019-10-10media: ti-vpe: vpe: don't rely on colorspace member for conversionBenoit Parrot
Up to now VPE was relying on the colorspace value of struct v4l2_format as an indication to perform color space conversion from YUV to RGB or not. Instead we should used the source/destination fourcc codes as a more reliable indication to perform color space conversion or not. To do so, we rework the csc module to use "struct v4l2_format *" as parameters, and reorganize the coefficients tables in a more logical way.

2019-10-07cec: add cec_adapter to cec_notifier_cec_adap_unregister()Hans Verkuil
It is possible for one HDMI connector to have multiple CEC adapters. The typical real-world scenario is that where one adapter is used when the device is in standby, and one that's better/smarter when the device is powered up. The cec-notifier changes were made with that in mind, but I missed that in order to support this you need to tell cec_notifier_cec_adap_unregister() which adapter you are unregistering from the notifier. Add this additional argument. It is currently unused, but once all drivers use this, the CEC core will be adapted for these use-cases.
