The first one is there to deal with analog TV properties, creating properties such as the TV mode, subconnectors, saturation, hue and so on. It's created by calling the drm_mode_create_tv_properties() function. The second one is there to deal with properties that might be useful on a TV, creating the overscan margins for example. It's created by calling the drm_mode_create_tv_margin_properties(). However, we also have a drm_atomic_helper_connector_tv_reset() function that will reset the TV margin properties to their default values, and thus is supposed to be called for the latter set. This creates an ambiguity due to the inconsistent naming. We can thus rename the drm_atomic_helper_connector_tv_reset() function to drm_atomic_helper_connector_tv_margins_reset() to remove that ambiguity and hopefully make it more obvious.

While the select subconnector property is stored in the kernel by the drm_tv_connector_state structure, the subconnector property isn't stored anywhere. Worse, the select subconnector property is stored in a field called subconnector, creating some ambiguity about which property content we're accessing.

Despite that property name being generic, its content isn't and has been driver-specific which makes it hard to build any generic behaviour on top of it, both in kernel and user-space. Let's create a new bitmask tv norm property, that can contain any of the analog TV standards currently supported by kernel drivers. Each driver can then pass in a bitmask of the modes it supports. We'll then be able to phase out the older tv mode property.

However, the command line parsing mode considers all dashes as the separator between the mode and the bpp count. Let's rework the parsing code a bit to only consider a dash as the bpp separator if it before a comma, the options separator.

The heavy lifting will then be done by the drm_mode_create_from_cmdline_mode() function. In the case of the named modes though, there's no real code to make that translation and we rely on the drivers to guess which actual display mode we meant. Let's modify drm_mode_create_from_cmdline_mode() to properly generate the drm_display_mode we mean when passing a named mode.

Never used for broadcasting, but sometimes used as a hack to play NTSC content in PAL regions (e.g. on VCRs). - PAL_N - PAL with alternative chroma subcarrier frequency, 3.58205625 MHz. Used as a broadcast standard in Argentina, Paraguay and Uruguay to fit 576i50 with colour in 6 MHz channel raster. - PAL60 - 480i60 signal with PAL-style color at normal European PAL frequency. Another non-standard, non-broadcast mode, used in similar contexts as NTSC_443. Some displays support one but not the other. - SECAM - French frequency-modulated analog color standard; also have been broadcast in Eastern Europe and various parts of Africa and Asia. Uses the same 576i50 timings as PAL. Also added some comments explaining color subcarrier frequency registers.
