From f902c1e95d5dfe5102f8467d69dc51d505f832ee Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 7 Jun 2017 11:46:12 -0300 Subject: [media] cec: add CEC_CAP_NEEDS_HPD Add a new capability CEC_CAP_NEEDS_HPD. If this capability is set then the hardware can only use CEC if the HDMI Hotplug Detect pin is high. Such hardware cannot handle the corner case in the CEC specification where it is possible to transmit messages even if no hotplug signal is present (needed for some displays that turn off the HPD when in standby, but still have CEC enabled). Typically hardware that needs this capability have the HPD wired to the CEC block, often to a 'power' or 'active' pin.

The structure contains a 'time_t', which will be redefined in the future to be 64-bit wide, causing an incompatible ABI change for this ioctl. As it turns out, neither of the drivers currently sets the timestamp field, and it is presumably useless anyway because of the limited resolutions (no sub-second times). This means we can simply change the structure definition to use a 'long' instead of 'time_t' and remain compatible with all existing user space binaries when time_t gets changed. If anybody ever starts using this field, they have to make sure not to use 1970 based seconds in there, as those overflow in 2038.
