[GIT PULL] Synopsis DesignWare HDMI driver development updates

[Russell King]

David,

Please incorporate the latest Synopsis DesignWare HDMI driver development
updates, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-dwhdmi-devel

with SHA1 b2779af1fd087320ebde01614f770b12e2dc3e5c.

Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver.  This series of patches are based on a couple of dependent
commits from the ALSA tree.

Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
  part of the driver.
- clean up the phy configuration: to all lookups before starting to
  program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
  the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
  code)
- remove private hsync/vsync/interlaced flags, getting them from the
  DRM mode structure instead.
- implement interface functions to support audio - setting the audio
  sample rate, and enabling the audio clocks.

These are preparitory patches for the AHB audio driver and the I2S
audio driver (from Rockchip) for this IP.

This will update the following files:

[GIT PULL] Synopsis DesignWare HDMI driver development updates

[Russell King]

David,

Please incorporate the latest Synopsis DesignWare HDMI driver development
updates, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-dwhdmi-devel

with SHA1 dfbdaf50460479446a258ef781683e7d7d6349d7.

This series:
* adds support for interlaced video modes to the ipu-v3 driver
  and dw_hdmi bridge.
* reworks the dw_hdmi connector enable/disable support, to ensure that
  when DRM disables the output, it stays disabled irrespective of the
  hotplug state.
* adds support for connector forcing, so we can force the hotplug state
  for this connector.
* adds the ALSA AHB audio driver to the bridge: Iwai has acked the
  audio driver.
* a few fixes to the ACR calculations to allow more modes to work with
  audio on iMX6.

Fabio has independently tested this series, so all patches here carry
his tested-by tag.

This will update the following files:

 drivers/gpu/drm/bridge/Kconfig             |  12 +

Oh I sent the edid fix to Linus and was waiting for to backmerge before
pulling this, I've taken it now .

I've now dropped this into linux-next so that it can get some time there,
and still be merged during the 4.3 merge window should it open this Sunday.

[GIT PULL] Synopsis DesignWare HDMI driver development updates

[Russell King]

David,

Please incorporate the latest Synopsis DesignWare HDMI driver development
updates, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-dwhdmi-devel

with SHA1 6dc2e1bf8e0025db2ff8a35ee3e0bd88203d4402.

This is a re-send of the original pull request from the 15th July plus a
few more changes.

Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver.  This series of patches are based on a couple of dependent
commits from the ALSA tree.

Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
  part of the driver.
- clean up the phy configuration: to all lookups before starting to
  program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
  the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
  code)
- remove private hsync/vsync/interlaced flags, getting them from the
  DRM mode structure instead.
- implement interface functions to support audio - setting the audio
  sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
  again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
  reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name

These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.

One other difference from the previous pull request is that I've moved
the "drm/edid: add function to help find SADs" commit to the start of
the series.  This commit should be pushed into v4.2 to fix the build
error people have been reporting with the ALSA ELD helpers.  Let me
know if you want a separate pull request for that for your drm-fixes
branch.

This will update the following files:

[GIT PULL] Synopsis DesignWare HDMI driver development updates

[Russell King]

David,

Please incorporate the latest Synopsis DesignWare HDMI driver development
updates, which can be found at:

  git://ftp.arm.linux.org.uk/~rmk/linux-arm.git drm-dwhdmi-devel

with SHA1 1dbee1a3c38a8792c235048df1d709fc5ca3a185.

Apologies for this being late... these are the patches which I queued last
week after review on the mailing list, and have been tested by myself and
agreed to be pushed for the 4.1 merge window between Yakir Yang and myself.
If you're not taking stuff anymore, that's fine, I'll queue for the 4.2
window instead.

This set of patches adjust the setup of the HDMI CTS/N values for audio
support to be compliant with the work-around given in the iMX6 errata
documentation as part of the preparation for integrating audio support
for this driver, and also update the HDMI phy configuration for Rockchip
devices to improve the HDMI eye pattern.

This will update the following files:

 drivers/gpu/drm/bridge/dw_hdmi.c            | 54 ++++++++++++++++-------------
 drivers/gpu/drm/imx/dw_hdmi-imx.c           | 24 ++++++-------
 drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 14 ++++----
 include/drm/bridge/dw_hdmi.h                |  5 +--
 4 files changed, 51 insertions(+), 46 deletions(-)

through these changes:

Russell King (3):
      drm: bridge/dw_hdmi: combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts()
      drm: bridge/dw_hdmi: protect n/cts setting with a mutex
      drm: bridge/dw_hdmi: adjust n/cts setting order

Yakir Yang (3):
      drm: bridge/dw_hdmi: fixed codec style
      drm: bridge/dw_hdmi: separate VLEVCTRL settting into platform driver
      drm: rockchip/dw_hdmi-rockchip: improve for HDMI electrical test

Many thanks.
