[PATCH] CHROMIUM: drm: bridge/dw_hdmi: Eliminate unused cable_plugin

[PATCH] CHROMIUM: drm: bridge/dw_hdmi: Eliminate unused cable_plugin

[Douglas Anderson]

There's a member in 'struct dw_hdmi' called cable_plugin.  It's never
set to anything anywhere so thus is always false.  There's a bit of code
checking it, but since it's always false this must be dead code.
Eliminate it.

Note: if someone wants to figure out the intention of the original code
and implement whatever feature / fix was needed then we can drop this
patch.  The 'cable_plugin' member has been unused since the code was
first added in (9aaf880 imx-drm: Add mx6 hdmi transmitter support).

Except for the CHROMIUM: prefix this looks good to me:

Russell, do you have patches to this driver queued for v4.4 and plan to
pick this up into your tree or should I take it?

My current patch stack for imx-drm related stuff looks like this at
present:

drm: bridge/dw_hdmi: place PHY into low power mode when disabled
drm: bridge/dw_hdmi: start of support for pixel doubled modes
drm: bridge/dw_hdmi: remove CEC engine register definitions
drm: bridge/dw_hdmi-cec: add Designware HDMI CEC driver
cec: add HDMI CEC input driver
cec: add HDMI CEC core driver
drm: bridge/dw_hdmi: replace CTS calculation for the ACR
drm: bridge/dw_hdmi: remove ratio support from ACR code
drm: bridge/dw_hdmi: adjust pixel clock values in N calculation
drm: bridge/dw_hdmi: avoid being recursive in N calculation
drm: bridge/dw_hdmi-ahb-audio: allow larger buffer sizes
drm: bridge/dw_hdmi-ahb-audio: basic support for multi-channel PCM audio
drm: bridge/dw_hdmi-ahb-audio: parse ELD from HDMI driver
drm: bridge/dw_hdmi-ahb-audio: add audio driver
drm: bridge/dw_hdmi: improve HDMI enable/disable handling
drm: bridge/dw_hdmi: add connector mode forcing
drm: bridge/dw_hdmi: add support for interlaced video modes
gpu: imx: fix support for interlaced modes
gpu: imx: simplify sync polarity setting

I haven't yet decided what, if anything, from that stack I'm going to
try to get into the next merge window.  Given the lack of interest last
time I posted these patches, I'm loosing interest myself in trying to
get them merged, especially ones which are getting on for being 2 years
old.

This seems to be similar to Sascha's "drm: bridge/dw_hdmi: remove unused
code" patch, except that the hdmi_disable_overflow_interrupts function
could be removed too.

I'm still very interested to see at least the "gpu: imx: fix support for
interlaced modes" and "gpu: imx: simplify sync polarity setting" merged.
May I take them into the imx-drm tree separately?

Or, if I can influence your decision in this matter, I'd prefer if you
could once more resend last month's series with Thierry in Cc:, and he'd
either queue them with my Ack for the imx-drm patches or give his Ack
for you or me to queue them.

The "gpu: imx:" patches sound like they are standalone, so taking them
through the imx-drm tree would be the easiest.

Taking just those screws up the rest of the series, as I previously

Have you acked my patch set sent in August, after I relied saying that
the series needs to be kept together?

Philipp sent a tested-by, but that was about the only attributation
I received from posting the set, so I only sent David what I was fully
happy to send at the time.  I'm willing to send:

drm: bridge/dw_hdmi: improve HDMI enable/disable handling
drm: bridge/dw_hdmi: add connector mode forcing
drm: bridge/dw_hdmi: add support for interlaced video modes
gpu: imx: fix support for interlaced modes
gpu: imx: simplify sync polarity setting

now, which are patches 3, 4, 5, 11 and 12 from the original 12 patch
series.

The actual audio patches I think need to be held _even_ longer, because
it's unclear what's happening with ALSA in regard to HDMI audio.  There's
also the need to sort out what's going on with CEC (thanks to the late
arrival of the CEC project by Hans) which may influence how the HDMI
audio part gets to hear about the display's capabilities.  So, yet again
I can see audio missing the next merge window, which is just how it's
been for the last two years.

Actually, right now I think we ought to say: sod it, these patches have
been around for long enough that they should just be merged, and then
we'll sort out whatever changes are necessary later when the CEC and
audio situation finally gets sorted... but are you happy with having
what is essentially an ALSA driver in drivers/gpu/drm/bridge?  If not,
why haven't you responded to the many times that the patches have been
posted?

At this stage, I'm getting to be very rebelious, and it's very tempting
for me to say "sod you" or just drop the work entirely if you have any
objections.  I feel I've put fsck loads of work into this area for
very little mainline progress, and I'm just not going to continue doing
that.

If you want to see them merged, how about sending me an Acked-by for
these patches?  You were copied on them in August, and there was a
deathly silence from _everyone_ on the initial set of patches.

There's been a few changes to "gpu: imx: fix support for interlaced modes"
and "drm: bridge/dw_hdmi-ahb-audio: add audio driver" as per the (little)
review that was done in August, but other than that, the patches are
essentially the same, just rebased on top of (now) -rc4.

Maybe some people can also take a look at the CTS/N changes, and maybe
back me up against Doug Anderson, so I'm not feeling like I can't merge
those patches due to the lack of concensus.
