5ca86eae55 macintosh: fix possible memory leak in macio_add_one_device()
Afer commit 1fa5ae857b ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically. It
needs to be freed when of_device_register() fails. Call put_device() to
give up the reference that's taken in device_initialize(), so that it
can be freed in kobject_cleanup() when the refcount hits 0.

macio device is freed in macio_release_dev(), so the kfree() can be
removed.

Fixes: 1fa5ae857b ("driver core: get rid of struct device's bus_id string array")

a0542d2c45 macintosh/via-pmu-backlight: Use backlight helper
backlight_properties.fb_blank is deprecated. The states it represents
are handled by other properties; but instead of accessing those
properties directly, drivers should use the helpers provided by
backlight.h.

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

This is a tentative to write above the stack. The problem is encoutered
with tests added by commit 38608ee7b6 ("bpf, tests: Add load store
test case for tail call")

This happens because tail call is done to a BPF prog with a different
stack_depth. At the time being, the stack is kept as is when the caller
tail calls its callee. But at exit, the callee restores the stack based
on its own properties. Therefore here, at each run, r1 is erroneously
increased by 32 - 16 = 16 bytes.

This was done that way in order to pass the tail call count from caller
to callee through the stack. As powerpc32 doesn't have a red zone in
the stack, it was necessary the maintain the stack as is for the tail
call. But it was not anticipated that the BPF frame size could be
different.

Let's take a new approach. Use register r4 to carry the tail call count
during the tail call, and save it into the stack at function entry if
required. This means the input parameter must be in r3, which is more
correct as it is a 32 bits parameter, then tail call better match with
normal BPF function entry, the down side being that we move that input
parameter back and forth between r3 and r4. That can be optimised later.

Doing that also has the advantage of maximising the common parts between
tail calls and a normal function exit.

With the fix, tail call tests are now successfull:

  test_bpf: #0 Tail call leaf jited:1 53 PASS
  test_bpf: #1 Tail call 2 jited:1 115 PASS
  test_bpf: #2 Tail call 3 jited:1 154 PASS
  test_bpf: #3 Tail call 4 jited:1 165 PASS
  test_bpf: #4 Tail call load/store leaf jited:1 101 PASS
  test_bpf: #5 Tail call load/store jited:1 141 PASS
  test_bpf: #6 Tail call error path, max count reached jited:1 994 PASS
  test_bpf: #7 Tail call count preserved across function calls jited:1 140975 PASS
  test_bpf: #8 Tail call error path, NULL target jited:1 110 PASS
  test_bpf: #9 Tail call error path, index out of range jited:1 69 PASS

drm/vc4: vec: Add support for more analog TV standards
Add support for the following composite output modes (all of them are
somewhat more obscure than the previously defined ones):

- NTSC_443 - NTSC-style signal with the chroma subcarrier shifted to
  4.43361875 MHz (the PAL subcarrier frequency). 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.

but it's up to each and every driver using that function to properly reset
the state of these properties leading to inconsistent behaviours.

Let's create a helper that will take care of it.

drm/probe-helper: Provide a TV get_modes helper
Most of the TV connectors will need a similar get_modes implementation
that will, depending on the drivers' capabilities, register the 480i and
576i modes.

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.

drm/client: Remove match on mode name
Commit 3aeeb13d89 ("drm/modes: Support modes names on the command
line") initially introduced the named modes support by essentially
matching the name passed on the command-line to the mode names defined
by the drivers.

This proved to be difficult to work with, since all drivers had to
provide properly named modes. This was also needed because we weren't
passing a full blown-mode to the drivers, but were only filling its
name.

Thanks to the previous patches, we now generate a proper mode, and we
thus can use the usual matching algo on timings, and can simply drop the
name match.

drm/modes: Properly generate a drm_display_mode from a named mode
The framework will get the drm_display_mode from the drm_cmdline_mode it
got by parsing the video command line argument by calling
drm_connector_pick_cmdline_mode().

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.

drm/modes: Add a function to generate analog display modes
Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and
625-lines modes in their drivers.

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.

drm/connector: Add TV standard property
The TV mode property has been around for a while now to select and get the
current TV mode output on an analog TV connector.

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.
