However, that property is getting deprecated, so let's rename that function to mention it's deprecated. We'll introduce a new variant of that function creating the property superseeding it in a later patch.

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 enum 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, and the property creation function will filter out the modes not supported. We'll then be able to phase out the older tv mode property.

Since those modes are fairly standard, and that we'll need to use them in more places in the future, it makes sense to move their definition into the core framework. However, analog display usually have fairly loose timings requirements, the only discrete parameters being the total number of lines and pixel clock frequency. Thus, we created a function that will create a display mode from the standard, the pixel frequency and the active area.

However, it can still be useful, for example to avoid any boot time artifact, to set that property directly from the kernel command line. Let's add some code to allow it, and some unit tests to exercise that code.

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.

That implementation will also need to set the preferred flag and order the modes based on the driver and users preferrence. This is especially important to guarantee that a userspace stack such as Xorg can start and pick up the preferred mode while maintaining a working output.

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.
